Westinghouse Heavy Duty Portable Generator – Best High-Performance Generator

This generator is for the boater who is looking for the most powerful solution out there. He is looking to bring the comfort of this own home on to the boat. This can power almost everything that can be used safely on a boat. With models of this generator cranking up to 15,000 peak watts and up to 12,000 running watts, this generator is something that most people would consider “too much”. The smallest generator of this line up puts out 5,300 Running Watts and 6,600 Peak Watts, which is still plenty if you ask me, but everyone has different needs.

You can fire this machine with ease, considering the fact that it comes with a button that you just push. The gas tank is also huge, with a 6.6-gallon limit. Also, there is a fuel gauge in the tank, enabling you to check the fuel level easily.

The huge gas tank is also a big advantage as it means that the generator can operate for more than ten hours at 50% load. Also, it is highly fuel-efficient and is capable of starting up even when exposed to low temperatures. In addition, the unit automatically shuts off when it detects the oil level is too low or the oil overheats. This prevents damage to the engine.

Goal Zero Yeti 1400 With Solar Kit – Best No-Noice, Eco-Friendly, Solar-Powered Boat Generator

The last, but certainly not the lest, generator I would recommend is the Goal Zero Yeti 1400 Lithium Portable Power Station. Obviously, this product is not for everyone, much like an all-electric car. 

The Goal Zero Yeti 1400 is a battery and sun-powered generator. It is a great alternative for the boater that hates noise, is eco-friendly, and doesn’t care about its price tag. This piece of advanced technology is a clean alternative to a 2,000-watt gas-powered inverter generator. It can produce a continuous 1,500-watt output and a surge capability of 3,000 watts. 

If you go for this product, make sure to opt for the solar kit. This will be the solar panel that generates the power to fill up the unit’s battery. For a full charge, it takes about 25 hours from a house outlet or 4.5 hours with the Boulder 100 Briefcase solar panel; with optimum solar conditions.

It might look expensive at first glance, but considering that it can be charged efficiently with the solar panel and you will not have to pay for gas, oil changes, and maintenance costs of a conventional generator, it starts to look more appealing. 

• Eco-Friendly
• Can be used indoors
• Relatively Heavy (72 Pounds)
• Can be charged with the sun
• Lack of mechanical parts means fewer problems and repairs
• Battery degrades over time

What Size Generator Do You Need For Your Boat?

When looking for a boat power generator, it’s essential to think about the size and power of the unit in question.

For boaters who only need to use a few small appliances and don’t have air conditioning on their boat, a small boat generator is just what they need. Smaller, portable generators are a great option for those who are short on space and need to keep their weight low. That said, they cannot power much.

Those with 30-amp electrical systems and average power needs, a 2,000-watt boat generator should be enough. This will start and run some small air conditioning units, and will easily power any other appliance you may want to use. That includes a microwave, which is an electricity pig, and uses a massive 1,000 watts.

Larger boats with bigger electrical systems can also run on a 2,000-watt generator. That said, those with bigger boats should keep in mind that only one air-conditioning unit can run on 2,000 watts at best. A larger, more powerful generator may be needed to fill their needs.

In the end, what capacity generator you decide for your boat is up to you. As long as you consider power output, storage space, and the weight you’ll need, you should be able to choose the best boat generator for the job.

5 Best Wind Generators For Sailboats (2024)

Wind generators, also known as micro turbines, have come a long way since their first appearance on the cruising scene back in the 1970's. Loud, relatively low output and large bladed, these forerunners of the modern day wind generators were both a mechanical marvel and a source of constant consternation. They were basically a small automotive alternator encased in an aluminum housing, with little thought into aesthetics or longevity. Cruisers equipped with an old Windbugger or K.I.S.S. wind generators come to mind as the loud boats in the anchorage no one wanted to be around.

As we all know, there are very few, if any, automotive products that last very long in a marine environment. A large stock of spare parts had to be stored in case of breakage, and daily maintenance consisted of checking the bearings, monitoring the voltage vs. wind speed for signs of decreased output, and rotating the blades into the wind when the boat position changed.

Today's best wind generators boast such features as CAD designed, self-feathering composite blades that are whisper quiet, brushless magnetic alternators, automatic braking and over-charge protection. Boxy aluminum housings have been replaced with sleek, carbon fiber and fiberglass nacelles.

While you may spend a small fortune on a wind generator that has all of these features and more, you can also opt for more budget friendly models, readily available from Amazon, Home Depot and other on-line retailers. The best wind generators are usually the most expensive, but when you are looking at the lower cost models, remember to add in the cost of wiring, mounting hardware, remote monitoring stations and installation, should you choose not to do the work yourself. Not all wind generators are purpose-built for the marine environment. Buyer beware: a turbine designed for the hobbyist on land will not stand up to the rigors of an offshore passage.

Table of contents

As with any mechanical device you are researching, it is a good idea to learn some of the terminology associated with the product. Not all of us know the meaning of 'swept area', 'power capture' or 'yaw error'. Likewise with the electrical side of the wind generator. Learning about output wattage, amps, and microprocessors can seem like a daunting task, but it is necessary to know these terms before you shell out hard earned cash for a quality wind generator.

Some features of wind generators, such as weather-proof coatings and low-noise operation, are common to all makes and models. The use of rare earth elements like Neodymium, (Nd2FE14B, used in magnetic rotors), can add hundreds of dollars to the price of some of these wind generators, but defiantly do add to the overall dependability of the unit.

Some of the more desirable things to look for in a wind generator are:

• Ease of Operation

Also known as plug-n-play, the simpler the set-up, the better. Choose a model that has built-in controllers, that ???makes for less complicated wiring runs. A remote monitor is handy to check on the status of the charging system without crawling into the battery room, or looking up to see if the blades are still turning. If you are ordering your generator and having it shipped, ask your salesman to be sure it has detailed assembly instructions and perhaps an owner's manual in either DVD or booklet form.

• Low Cut-In Speed 

Wind generators work best when the blades are humming along in 20 knots of wind, but that's not always the case. Low cut-in speed means your batteries are getting a charge in the lightest of airs, if only a trickle charge.

If you happen to be ashore when the wind kicks up, you don't want your turbine to spin wildly out of control. Some generators feature a type of automatic speed governor that slows the blades down before they self destruct. Back in the day, you had to pull down on a cord to apply the brakes, then climb up the mast or mounting pole and manually tie off the blades.

• Over-Charge Protection

A 'brake' also kicks in when the batteries are nearing or at full capacity, to prevent overcharging. Some controllers slow the rotation of the blades, others 'dump' the excess power generated through a resistor and heat sink. Wiring an in line reset-able fuse can prevent damage to your batteries should a malfunction occur within the charging system.

• Portability

If you are one of those part-time sailors who cruises for a few months, then dry-docks your vessel for the off-season, choose a light-weight portable wind generator you can set up at home to off-set your electric bill. In case of a hurricane or other emergency when there is no power for days at a time, your wind generator can power cell phone chargers, laptops and rechargeable battery stations. Removing your wind generator and locking it away in the cabin also deters thieves. Portable wind generators that are light can be mounted on higher surfaces without worrying about upsetting the balance of your boat. The heavier the generator, the lower it should be mounted, allowing for safe passage under and around those spinning blades, of course!

It is also a good idea to know your boat's needs and desires before settling for a low cost, low output wind generator. Everything that runs off a battery, including the DC to AC inverter, should be listed, along with their amp/hour draw, to determine how much power you will need to generate. Compare your toys with your reserve amps of your house battery bank. Do you just have a few LED bulbs and a masthead light to run at anchor? Then you can get by with a low output generator. Are you keeping a keg cooler, stereo, disco ball and Netflix going all night? When underway, are you powering SSB, weatherfax, VHF and radar? Then you need a rack full of batteries, and a wind generator with the capacity to keep them topped off.

Speaking of batteries, make sure the wind generator you purchase can charge all the different batteries available. Even if you only have wet-cell lead/acid marine batteries now, you may upgrade to AGM, Gel or even LiFeMgPO4 (Lithium Iron Magnesium Phosphate) batteries in the future. Some wind generators and their controllers are not advanced enough to charge these newer power sources.

Unless you are well versed in the application of electrical theory and DC current, you probably don't know much about wire size and current loss. Even the best wind generator will not function as advertised if the power can not get from the blades to the battery. If you have a long run from your generator to the battery bank you intend to charge, make sure your wires are correctly sized to prevent line loss from resistance and over heating. Most installation manuals will have a wire chart included for DIY installations, and there is always a help line to the manufacturer.

Here are four out of the dozens of wind generators out there that have positive reviews and some of the most desirable features.

1.) Superwind 350, 353

This German manufactured turbine features their patented Auto-Feathering Overspeed-Avoidance System. This is basically the same method a helicopter uses to gain lift, and settle back down. As the wind speed reaches 25 knots, the blades 'feather', or dump air, making them less efficient, and slowing their speed. As the wind lessens, the blades re-pitch, becoming more efficient. This action delivers a steady flow of charging current to the batteries, without going into a shut-down mode to prevent overcharging, as some models do. The Superwind generators also can be combined with solar panels and conventional diesel generators. The Superwind generator family also uses a brushless A/C stator for maximum control of noise and radio interference while the unit is producing power. Two sets of bearings in the 350 make for smoother operation and overall longer bearing life. Available in 12v, 24v, or 48v outputs. At close to 30 lbs, these units are well built and dependable. With a price tag right around $2,700 for the Superwind 350 kit, you can expect German Engineering at it's finest.  https://www.superwind.com/superwind-350-353/

2.) Automaxx

The Automaxx line of wind generators comes in 12v, 24v 48v models, in outputs from 400w up to 1500w. Survival wind speeds are listed at 110mph, but we hope you would never have to put that spec to the test. With very low cut-in speeds of less than 6mph, you will get charging amps on the slightest breeze. All their models come with auto-braking and manual braking system protection, over charge and over-speed protection. The 3600 rotation of the power head keeps the unit into the wind, even when you are docked or med-moored. Simple plug and play setup with an internal MPPT (Maximum Power Point Tracking) charge controller makes the DB400 an easy to install unit, while their other models feature a remote charge controller. Works well when combined with solar chargers. At 16.75 lbs., it is lighter in weight than the Superwind, and it's seven times less expensive at around $400.00 for the DB400.

3.) MarineKinetix MK4

One look at this brand's marketing home page is like an advanced course in wind generator physics. The list of specs for it's models is truly impressive. Not only do they boast all the latest technologies featured in their product, they explain all the scientific jargon they use in terms us simple sailors can understand. They have been providing wind generators to the sailing community for 8 years now, and have a devoted following.

If you need to know the difference between $400.00 wind generators and $1,800 units, check out the product overview section of their website.

The MarineKinetix brand has the the industries best 3 year limited warranty, so they must be pretty sure about their product.

The 12v models of this brand are currently out of stock, due to parts supplier back-orders, but if you are in the market, there are plenty of 24v and 48v units in stock.  https://store.marinebeam.com/marinekinetix-mk4-marine-wind-generator/

4.) Rutland 1200

One of the quieter wind generators out there, the U.K. made Rutland has a long track record of dependability and customer satisfaction. A manual switch is used to stop the blades when high wind is expected, there is no auto-brake. The Rutland can be combined with solar panels up to 20A, and can be also be used with deep cycle gel or AGM batteries, and there is a remote digital display available. One of the Rutland's best features is it's Tri-namic Blade profile design, which achieves low start-up speeds, silent operation in any wind, and maximum power transfer from wind to rotor. Overall good performance and features for the $1,600.00 price tag. https://www.emarineinc.com/Rutland-1200-Wind-Turbine

5.) DuoGen-3

Wind generators are a fairly common sight in most anchorages, and towable generating devices have been around for some time. The DuoGen-3 combines the two into one multi-use charging system. Underway, the high strength carbon fiber mast is lowered down to submerge the blades. At anchor, the unit functions like a typical wind generator. The results are impressive. In the water mode, the DuoGen-3 generates 200 Watts @ 16 amps cruising at 8 knots. Wind generators do not do well sailing downwind, so this may just be the answer. Available in 12v and 24v versions. Charging regulators are not included, so monitors and controllers have to be matched to the unit and sourced locally. https://eclectic-energy.co.uk/

Choosing the right wind generator for your vessel should be a pretty straightforward process, once you have an idea of your needs, the area you will be cruising in, and how long you expect to be 'off the grid'. If one generator is simply not enough because of the size of your battery banks and the load you put on them, you may need to purchase a pair of turbines. Customer support and availability of parts may be the determining factor in your purchase. Talk to other wind generator owners, and get a feel for what they have experienced with their current of former wind generators.

Choosing a Generator for Your Sailboat

• By Ed Sherman
• Updated: November 14, 2018

You can’t take it anymore: Your 1990s vintage cruising sailboat didn’t come equipped with a factory-­installed air-conditioning system or an alternating-current generator to power it and the other AC appliances you’ve brought aboard. Since you’ve owned the boat, though, you’ve turned into a real believer in global warming as you try to sleep through sweaty nights on board, and finally you’re ready to pull out your wallet and do something about it.

So, where do you begin? The first step is to analyze how much electrical power you are going to need. Since your boat had a basic shore-power system when you bought it, you already have some idea of your small-appliance usage, things such as hair dryers, the coffee maker and maybe even a small TV. But now you need to think in terms of running this same gear while at anchor. Additionally, if the standard-equipment shore-power option for your boat at the time of purchase was a 30-amp service, as is most often the case here in the United States, you might discover that it’s inadequate to run that new reverse-cycle air-conditioning system you’re dreaming about.

This is an area where, in my experience, a lot of boat owners go into denial as they discover that more power consumption adds considerable cost. Everything you’ve read about marine electrical systems so far tells you that air conditioning and refrigeration use a lot of power. But how much? The good news here is that these units have become more efficient in recent years and the power needs are not as great as they were when your boat was new. As an example, a modern 18,000 Btu reverse-cycle system from Dometic Corp. will need about 15 amps of AC power to get the job done. A 10,000 Btu unit is going to draw around 8 to 10 amps, depending on your location and whether you are heating or cooling.

Analyze Your Needs

The first step is to do an honest load analysis to see how much electrical power you will need. This is typically measured in thousands of watts, or kilowatts. The operative phrase here is: Don’t cheat. If you want to luxuriate in air-conditioned comfort 24-7 while cruising, it’ll cost you. Unlike powerboats, most cruising sailboats come equipped with liquefied petroleum gas stoves and ovens, so one of the major power consumers (an electric galley) is not a concern here.

All said, you are probably going to be looking at generators in the 4 to 12 kW size range. The typical owner of a 40-something-foot sailboat who wants to power up a reverse-cycle air-conditioning system, small galley appliances, a refrigeration system using either AC or DC power, a water heater and a battery charger is going to want an 8 kW generator. Larger boats that might end up having a clothes washer and dryer, larger reverse-cycle heating and cooling unit and water heater can easily end up in that 12 kW output range. The American Boat and Yacht Council offers a free trial membership with access to the relevant electrical power ­standard (E-11), including a complete load analysis worksheet for those who are so inclined and want a detailed account of their electrical needs. Simply go to abycinc.org to gain access via the consumer section of the site.

A quick way to determine your AC power needs is to look for the mandated label on each appliance. It is required to tell you either the operating voltage and amperage draw or the operating voltage and wattage.

Either way, a simple equation can be applied to get the info you need: Volts multiplied by amps equals watts; or watts divided by volts gives you an amperage value. Add the number of watts each device requires and you will get an idea of what size generator you’ll need. Remember that it takes 1,000 watts to make 1 kilowatt. Understand that this method will actually give you a result that does not take into account the fact that you might not be running all of your appliances simultaneously. The ABYC load analysis method found in the ABYC E-11 standard offers some diversity adjustments that are more conservative and reflective of the real world.

Although modern ­generators are not as sensitive to running with a light electrical load, most installers will tell you that running them at 70 to 80 percent of their maximum capacity is better for the engine. The risk here is carbon buildup in the engine’s combustion chambers if run with a light load for extended periods. So, this is a case where significant overkill is not such a good thing.

Practical Concerns

In addition to the electrical load you need to meet with your new generator, you should also be considering its weight and physical dimensions. Will the generator fit into the space you have available? The units I compared (see “Generators by the Numbers,” page 82) ranged in weight from a low of about 270 pounds for the 5 kW Fischer Panda to a high of just under 700 pounds for an 11.5 kW Kohler. This amount of weight dictates that when installing a generator on a monohull, you’re going to want to keep it on the centerline of the boat. Typically, this works out well because most sailboats built from the early ’90s on will have adequate space aft of the propulsion engine to fit in new generator. Multihulls offer more options on that front.

What might be a concern with the monohull is service access, not only for the generator itself, but for things like the propeller shaft stuffing box and shaft coupling. I’ve inspected many boats where the only way to access a leaking shaft seal was to lift the generator out of the way!

Wherever you end up installing your new generator, you need to be able to gain access to all the service points on the unit.

The physical dimensions of the generator could end up being a game changer too, so you’ll need to measure your boat’s available space carefully and compare that to the specifications for the units you are considering. You will also need to determine whether the unit will fit with a sound shield installed or not. Understand that some of the generators offer a sound shield as an option only. The presence of a sound shield, or your ability to insulate the space where you are going to have this generator mounted, could make a difference not only in size requirements but also noise issues while running.

As an example, comparing a Fischer Panda unit that comes with a standard sound shield, we get dimensions of 23 inches by 17 inches by 22 inches. A similarly rated Cummins Onan unit, which also comes with a standard sound shield, is 26 inches by 23 inches by 21 inches. A Westerbeke with a similar rating but with optional sound shield measures 36 inches by 23 inches by 25 inches. That 13-inch spread in length between the Fischer Panda and the Westerbeke could mean the difference between a doable install in the space available on your boat or not.

Finally, wherever you end up installing your new generator, you need to be able to gain access to all the service points on the unit. Can you get that oil filter off as installed? Can you access and change the water-pump impeller without needing an emergency ­chiropractic visit? These are questions that will need answers.

Power Perks

Several features related to newer generators are worth considering. One is whether the unit is equipped with digital controls that may also allow for self-diagnostics and integration to onboard networking that you or a former owner may have installed on the boat.

From a maintenance standpoint, you’ll also want to know whether the water-cooling system for the engine driving your generator is raw- or freshwater cooled. Raw water might save money initially, but will cost in the long run.

Buyers Beware

I can’t emphasize this enough: This sort of upgrade does not qualify as a do-it-yourself project unless you have ­considerable mechanical skills and experience, and labor will be a major addition to the overall cost of the installation.

Also, when you compare different units, study the supplied components carefully. Does the unit come with a remote display and control panel? What additional parts will you need? These will likely include an exhaust system, starter battery and cables, and raw-water supply hoses and a seacock. And don’t forget about wiring the generator ­into your existing, or possibly a replacement, AC ­distribution panel board. These items can add considerable cost above and beyond the generator prices shown in “Generators by the Numbers.”

If you are planning on cruising far afield with your new generator, you should also think about parts and service availability, not to mention its warranty.

Lastly, if you are planning on cruising far afield with your new generator, you should also think about parts and service availability, not to mention its warranty. As part of my ­research for this article, I looked at units from Cummins/Onan, Fischer Panda, Kohler, Northern Lights and Westerbeke. All five brands have extensive global dealer networks, so ­locating a service center that can help is just an internet search away. As for warranties, I’ve noted them in the “Generators by the Numbers” table. Keep in mind when reviewing this ­information that it is based on likely choices from the ­individual company’s offerings for a boat in the 35- to 45-foot size range. Also understand that the prices quoted are list price. Several of the dealers I spoke with suggested that discounts of $1,500 to $2,000 are quite common. That said, if you spot something you think is a deal, be certain of what you are actually getting, ­especially if it’s at a ­remarkably ­discounted price.

A green alternative

Considering the cost of installing a generator — estimated at $15,000 to $20,000, or possibly more depending on your boat and the power output selected — you might consider some alternatives.

How about essentially silent AC power via a direct-­current-to-alternating-current inverter and adequate storage capacity that relies on the latest high-capacity battery technology?

Marine electrical systems have evolved considerably over the past decade or so, and I’m at the point now where I question the need for an onboard AC generator for most cruisers, though some might still benefit from installing a DC generator to supplement solar-, wind- or water-driven charging solutions.

The current density of high-end absorbed glass mat and lithium-ion batteries has improved by 20 to 30 percent due to their inherent capacity compared to older flooded-cell batteries. They can also be discharged to deeper levels without damage and recharged much more quickly due to high absorption rates. I’m of the opinion that it might be time to look at alternative power if you are willing to spend the kind of money we are talking about with an AC generator upgrade for an older boat.

As quiet as they might claim to be, that incessant drone of an AC diesel generator, not to mention the however faint odor of diesel exhaust fumes, is going to be a reality. It’ll have to run all night if you want that AC keeping you cool.

Instead, you could run the DC generator in the morning to replenish your batteries from an overnight discharge. Or, let your solar panels and wind generator do the job. I like the concept of not having to run an engine continuously to get my AC power.

Buyer’s Guide

Power Output

The first thing you need to do is find out what you are going to power on your boat trips? If you will power sensitive electronics and other small devices, then a small size generator with 1600 to 1800 rated power output is enough. But to power large appliances, you will need at least 2200 rated watts.

Moreover, if you are going to power both small and big items simultaneously, then make a list of all those things and write their watts to calculate the total required power. In this way, you will find a perfect unit for your boat.

To make this clear and understandable for you, we have given an example below.

For the above setup, 5300 watts are needed to start all the appliances together, and 3600 watts are needed to run all the appliances at one time. If you know how to do load management, you can run all these appliances on a 3600 watts generator. The trick here is to add load one by one to your generator. Once they release the extra wattage needed to start the appliances, you can add more load. Smaller generators are cheap to buy and easier to maintain. They also have a low running cost.

Type of Fuel

It is recommended not to use propane on a boat because liquid gas can be hazardous. But nothing is stopping you from buying a dual fuel generator for other uses. You can buy a dual fuel generator for your boat and use only gasoline while you are out in the water. Gas is a safer option for boats. Overall, a dual fuel generator gives you versatility when it comes to the fuel type. When you are using the same generator at home, office, or RV, you can use propane without any issues. Propane is cheaper than gas, burns cleaner, and gives a better runtime in smaller generators. Gas availability is also jeopardized during natural disasters and infrastructural problems.

Control Panel

You must look for a generator that offers maximum options on the control panel. When you are out on the boat, you want things simple and under control. A fully advanced model will have an odometer, meter readings, on/off buttons, a choke, and power outlets on the control panel.

Power Outlets 

The next thing to look at is power outlets. Make sure the generator you are selecting has your desired power outlets. There must be two 120V AC outlets and a DC outlet along with a USB port. Also, try to get a generator with GFCI-protected power outlets.

Tank Capacity and Runtime

As you are buying a portable generator for a boat, tank capacity and runtime are vital to consider. It would help if you went for long boat trips for units with big fuel tanks; otherwise, a 1-gallon tank is enough to go for a 6 to 7-hour trip.

But a big fuel tank like 2 gallons or more is not enough if your generator is not fuel-efficient. Make sure your unit has an eco-mode. However, runtime also depends on the load applied.

Noise Level

It is always recommended to go for portable inverter generators to use on a boat to produce less operational sound. Less than 65 dB (A) operational noise is quite bearable.

Parallel Capability

For boat trips, a parallel capable generator is a must so that you can generate more power when needed. Paralleling also allows you to run more appliances as you get twice the number of power outlets. Having two small generators is always an edge because they can be used for two different purposes or at different places.

Throttle Control

One of the biggest benefits of buying an inverter generator is that it comes with a throttle control system. Throttle control or eco mode is a feature that helps in adjusting the engine output according to the load applied to it. If your generator has less load on it, it will reduce the output and increase it when the load is high. Such features help increase fuel efficiency and reduce operational costs.

Portability

You will have to carry your generator to your boat every time you set sail. Hence, look for a generator that comes with high-quality wheels, an ergonomic carry handle, and push/pull bars. You will be using this generator for your home or other purposes when you are not on your boat. So, you must never ignore the portability features in your generator.

Safety Features

Low-oil alert with shutdown feature and overload protection are the two safety features that must be part of your generator. Other than these, if there is an emergency stop button, then it will be a plus.

Weight and Warranty

Make sure your portable generator is light in weight. Also, it must have an excellent gripping handle to carry it quickly to the boat. Other than weight, the warranty period also needs to be considered. At least your generator has a 2-year warranty period.

Environmental Conservation

When you are on a boat, don’t ignore the environment. Buying a generator without EPA and CARB (for California residents) isn’t legally and ethically right. Uncertified generators hurt the environment by producing toxic and harmful chemicals. Hence, you must look after such things as well.

The last thing to consider is price. When you look for advanced generators with all the latest features, you will have to pay more. Such generators are user-friendly and easier to maintain. On the contrary, basic models are cheaper but often have a higher operating cost.

How to prepare a portable generator for a boat?

Before you can use a portable generator for a boat, you need to make sure that it is fit for the boat. All the electrical connections, spark plugs, screws, and other hardware will need to be covered with water-resistant materials. You will need to hire a professional to prepare the generator for the boat. Don’t worry. It can be reversed, and you can use your generator for non-boat purposes. However, it is better to keep a separate generator for your boat. You can use waterproof spray or cowling to protect your generator. For more detail, please check out the video here .

What’s the best place to install the generator on a boat?

First of all, it is not a good idea to install the generator permanently on a boat. You must keep it in a dry locker when it is not in use. The aft deck is the most appropriate place to keep a generator when it is running. A swim platform is also a good place for running the generator. To keep your generator secure, use metal brackets and pads. Pads help in reducing the vibration and running sound. Avoid placing a running generator near the cabin, windows, and doors of the boat. The cabin can fill up with smoke pretty soon, and it can become a health hazard.

How to can I connect my generator to the boat?

Some boats come generator ready. Other needs to be wired to make them generator ready. If your boat is not generator ready, you must hire a professional electrician to this task for you.

Is it safe to use a dual fuel generator or run a propane generator while on a boat?

It is safe to buy or use a dual fuel generator on a boat, but it is not safe to run it on propane. In case of leakage, the liquid propane will fill up the bilge, and any spark may have devastating effects on your life.

Do I need to ground a generator to use on a boat?

No, there is no need to  ground your generator  to use it on a boat. Grounding is necessary when your generator is hooked up to the building wiring.

Suppose the appliances and electronics are plugged in through electrical outlets, and the generator’s metal parts are linked to the frame of the generator. In that case, you won’t need to ground your generator.

What safety measures should I take while using a boat generator?

• Never refuel your generator while you are on a boat.
• Avoid running your generator near doors and windows to prevent your cabin from filling up with carbon monoxide.
• Avoid starting your generator near the damp patches.
• Make sure there is no fuel leakage.
• Keep your generator high enough on the boat to protect it from waves.

What are the maintenance needs of a portable boat generator?

When you are running your portable generator on a boat, you need to be more careful and vigilant about its maintenance. Inspect your generator after every tour and ensure that its components are free from water. Make sure that waterproofing is all okay. Besides post-tour inspection, you must also do periodic maintenance for your generator like spark plug inspection, checking engine oil and oil/air filter, and battery recharging.

A boat trip with a generator on board is always a pleasant experience. When you have ample power for all your appliances, you enjoy your time out in the sea with your family and loved ones to the maximum. You can cook better, sleep better and enjoy more. All the generators reviewed above are of high-quality and will go a long way with you.

Blowin’ in the Wind: The Best Marine Wind Generators

Whether you're walking down a road, climbing a mountain or sailing on the sea (with a white dove, maybe), there's one constant: Wind. 

Bob Dylan may have had all sorts of other ideas in mind when he wrote "Blowin' in the Wind," but the idea stands. When the wind blows, power is supplied. The times, they are a-changin', and we boaters need power out on the water for motor batteries , stereos, marine electronics, lights, bilge pumping and what have you.

Sure, when you're in your marina slip, you can just hook up to power. But when you're out on the water, that's not exactly feasible. Plus, it's always good to do everything we can to save the environment, reduce our carbon footprint and what-not.

Today, we're going to discuss the best marine wind generators and turbines for boats to answer your power problems whether you're a leisure powerboater, a liveaboard sailor  or own the wooden schooner Water Pearl (that would be Bob's, of course). More Dylan references may or may not ensue.

What Is a Marine Wind Generator?

You know those wind turbines you see standing tall on land? Well, a marine wind generator is essentially the same thing. It's just smaller and attached to a boat (or a magic swirlin' ship).

Swirlin' ships aside, marine wind generators work by harnessing the kinetic energy of air, or to be exact, the wind. Once caught, the wind is converted to a rotational motion that turns an alternator, which then produces electrical energy. This energy can be used immediately or stored in batteries (12V or 24V) for later use. Voila, it really is magic!

Parts of a Marine Wind Generator

• Blades are those things on the end that turn (similar to the blades on a ceiling fan). They're connected to a shaft that turns with the blades.
• A tower or mast , usually about 9' tall, is the pole that attaches to the boat (like a sailboat mast) and holds the blades up in the air.
• Stay poles , usually two 8' poles, are used to hold up the mast. They're attached at an angle to keep the mast in place.
• Clamps, crimp rings and TY wraps are used to keep it all together.
• Control panels and electronics let you make sure everything is operating as it should.

Benefits of a Marine Wind Generator

• Economical (free energy!)  - This is probably the biggest reason to consider a marine wind generator. Once you've made the initial purchase cost, you've got all that free energy coming in. We boaters need all the free we can get.
• Relatively low maintenance  - Marine wind generators are pretty much an install it and forget it kind of thing. Like the song, it's just there blowin' in the wind.
• Environmentally friendly  - We all want to conserve energy, go green and save the environment (or we should if we really love the boating lifestyle like we say we do). Marine wind generators don't add to air or water pollution, and they don't emit greenhouse gases.

Disadvantages of a Marine Wind Generator

• Noise and vibration:  They can be quite noisy (especially when the wind is really kicking it up). You'll be on a rockin' boat whether you want to or not.
• No wind, no power:  This one is self-explanatory.
• Very high winds:  On the flip-side, marine wind generators can be damaged in very high winds. There are, of course, ways to avoid this problem. You can use a regulator or charge controller that senses the battery voltage and reacts in the appropriate manner. Some wind generators can change the pitch of each blade in response to the wind. Others have flexible blades that bend easier in the wind (this method, however, can cause even more noise).

Featured Boat Care Product

Check Price on Amazon - Better Boat's Boat Soap is 100% biodegradable and safe to use in marine environments. It rinses clean and doesn't leave a slippery residue. Simply spray with a hose and nozzle.  Use a microfiber cloth if you need a bit more scrubbing power.

What to Consider When Choosing a Marine Wind Generator

• Decide how much power you'll need for things like the stereo, navigational electronics, refrigerator, lights, laptops and other devices.
• Where do you spend most of your time on your boat? Ocean or inland? You'll want to gauge the amount of wind generally found in that area.
• What are your normal cruising speeds? Obviously, any wind is good, but most marine wind generators don't provide much power below eight knots.
• What are the water and weather conditions in your normal navigational routes? You'll want to align your choice of wind generator with how rough or calm the water is, as well as the types of weather typically found. As an example, with higher wind speeds, you'll want a bigger blade sweep to get even more energy.
• Where do you want to put it on the boat? I've seen marine wind generators attached to the back of a sailboat, on a hardtop and at the very front of the boat. Take into consideration where it will be out of the way as far as foot traffic on the deck.
• Are there any noise restrictions? Remember when I said marine wind generators can be noisy? I wasn't kidding. Noise restrictions are a real concern in certain places: narrow inland waterways, residential communities and businesses.

Different Types of Marine Generators and Their Applications

Marine generators come in various types, primarily distinguished by their fuel source. 

Common types include diesel generators, propane generators, and gas generators to power your boat. Your choice among these will depend on factors such as your boat’s design, the availability of fuel, and your power requirements. 

Diesel generators, like the Cummins Onan Marine QD 3200, are known for their efficiency and longevity, making them an excellent choice for long trips. Gasoline generators, such as the Honda EU2200i, are typically more compact, suitable for smaller boats with limited space. 

Propane generators are a cleaner alternative, emitting fewer greenhouse gasses than their counterparts, but they require proper storage and handling for safety. 

Key Factors to Consider When Choosing a Marine Generator for Your Small Boat

Choosing the best marine generator requires understanding your boat’s needs and the generator’s specifications. Let’s explore the key factors to consider to ensure you choose a generator that will reliably meet your needs on the water.

Assessing Your Power Needs

The first step in selecting a marine generator is understanding your power needs. This involves listing all the devices and systems on your boat that require electrical power, from navigation systems and radios to kitchen appliances and lighting. 

After making the list, calculate the total power requirements. This information is typically found on the device’s label or in its user manual. 

Knowing your total power needs will guide you in selecting a marine generator that can meet these demands without straining its capacity.

Space Considerations on Your Boat

One unique aspect of choosing a marine generator for a small boat is the space limitation. It’s crucial to consider not just the generator’s size but also the space required for proper ventilation and access for maintenance. 

When selecting a generator, consider where it will be installed and whether there’s sufficient room for it. Compact and portable generators for boats like the West Marine Portable Generator or the Yamaha EF2000iSv2 Generator can be more suitable for smaller ones. 

Fuel Type and Availability

The type of fuel your generator uses is another crucial consideration. Different fuel types have varying availability, cost, storage requirements, and environmental impact. 

Diesel generators are typically more efficient and longer-lasting, but diesel fuel can be more challenging to store. Gasoline generators are more compact and have readily available fuel, but they tend to be less efficient. Propane is a cleaner fuel alternative, but it requires proper storage to ensure safety. 

Noise Levels and Comfort

Noise level is often overlooked when choosing a generator, but it can significantly impact your comfort on the boat. A noisy generator can disrupt your peaceful time on the water, making your journey less enjoyable.

When considering generators, look at their noise level ratings. Generators like the Honda EU2200i and the Cummins Onan Marine QD 3200 feature quiet operation, ensuring that your sea voyage remains a peaceful retreat.

Safety and Maintenance Tips for Your Marine Generator

Just like any other mechanical device, marine generators require regular maintenance to ensure their longevity and safety. Understanding the basic maintenance practices and safety measures can help you get the most out of your generator.

Regular Maintenance

Regular maintenance of your marine generator can prevent unexpected breakdowns and prolong its life. Maintenance tasks include regular oil changes, replacing air filters, checking the cooling system, and inspecting the generator for any signs of wear and tear.

Routine maintenance is also an opportunity to identify potential issues before they become major problems. It ensures your generator is in optimal condition to reliably power your boat, giving you peace of mind on your sea voyages. 

Proper Installation and Handling

Using a generator on a boat requires a keen awareness of safety considerations. Marine generators should always be installed in well-ventilated areas to prevent carbon monoxide build-up. 

Also, ensure that the generator’s exhaust system is appropriately installed and regularly inspected to avoid any leaks. Moreover, always handle fuel with care, and make sure you have appropriate fire extinguishing equipment onboard. 

Safety should be your top priority, ensuring your boating experience remains enjoyable and worry-free.

6 Best Generators to Take on a Boat – Your Easy Access to Power

When you’re out in the water, it doesn’t mean that you have to sacrifice having easy access to electrical power. Generators have come a long way in the last several years, allowing you to have all kinds of options. But depending on your boat, there are many things you need to take into consideration. Smaller boats probably won’t be able to handle a permanently installed generator. Which is why there are all kinds of smaller, more portable options out there. Noise is also a big consideration when you’re on a boat and have limited space. Inverter generators are quieter and more fuel-efficient, making them the unit of choice for use on a boat.

To find the best generator for a boat out there, we rated the top generator models by engine power, rated/maximum output, fuel tank capacity, noise level, weight, and portability. We also noted whether the generator had issues with the pull-starter, carb clearance for storage and oil fill. Engine power is an important consideration because you need to know that the generator you choose can keep up with the demands of whatever job you need it to do. With marine generators, it is especially important to note fuel tank capacity, because you don’t want to run out of fuel in the middle of nowhere. Since space is at a premium on boats, you will want to make sure the generator’s noise level stays at a comfortable purr, so it won’t interfere with any of your activities. Weight and portability to carry the generator to and from your vessel have also been considered. Each extra pound aboard a vessel will affect its speed and buoyancy, so it’s important to know your vessel’s capacity and consider the weight of the generator.

We searched out customer and expert reviews and product specs for each of the top generator brands and have listed our findings in the table below. The generators have been listed according to our ranking. Included also is a detailed review of each product , and a buying guide that we hope will clear up the most important things you need to know before taking a generator aboard.

Top 6 Generators for Boat Review 2024

Briggs & Stratton P2200

• Peak/rated watts: 2,200/1,700
• Engine: 110cc Briggs & Stratton OHV
• Fuel tank: 1 gal.
• Runtime: 8 hrs. (25% load)
• Outlets: (2) 120V Household, (1) 12V-5A, DC Outlet with USB Adapter
• Start type: recoil
• Noise level: 59 dB(A)
• Warranty: 2-year limited

The Briggs & Stratton P2200 functions as well as an ordinary generator that keeps up with the wattages coming in at 2,200 starting and 1,700 running watts. It does weigh in at the heaviest of all of them, 55 pounds, which is a good 11 pounds heavier than the Yamaha. This would make a significant difference to practical portability for people with back problems or tendonitis.

Some people say they liked the handle, others said the reviews of the 3,000 were mixed in with the 2,200, which confusingly stated that it contained a suitcase-style handle and wheels for east of portability. There were also complaints that the noise level it claims is not what they measured. Many users stated it is louder than the other varieties of generator, for example, the Honda. This would be especially problematic on a boat as sound is multiplied and carried easily over water.

Despite this, there is a switch for turning on “Quiet Power Technology,” which is extremely effective at limiting noise, but it cannot be used at capacity in this mode, although it does save on fuel by reducing RPMs. The PowerSmart mode adjusts the engine speed based on the electrical load.

Some people had difficulties with starting the Briggs-Stratton generator unless it was used quite regularly. Even then, its start is not easy – taking four pulls, a departure from the rest of the pack that start easily with one.

There is a handy LED light system to alert you of output, low-oil and/or impending overload. Also, it does have parallel capability to hook up and combine the power of two units together if you need more power.

• Fuel efficient
• Parallel outlet
• Two-person handle
• Flexible outlets
• Not shipped to California
• Lacks gas gauge and fuel shut-off valve
• Louder than claims
• Heaviest of all
• Our 9 pick for the: best 2000 watt generator
• Our 3 pick for the: best briggs and stratton generator
• Our 8 pick for the: best quiet generator
• Our 1 pick for the: best generator for tailgating

Honda EU2200iTAG 2200-Watt 120-Volt Super Quiet Portable Inverter Generator with CO-Minder

• Peak/rated watts: 2,200/1,800
• Engine: 121cc Honda GXR120
• Fuel tank: 0.95 gal.
• Runtime: up to 8.1 hrs. (25% load)
• Outlets: (1) 20A 125V Duplex, (1) 12V 100W (8.3A) DC
• Noise level: 48 to 57 dB(A)
• Warranty: 3-year residential and commercial

While both are quiet generators , it is quite possible the Honda EU2200i is quieter than the Yamaha. The EU2200i operates at 48 to 57 dBA, which is less noise than a conversation in held in “inside voices.” If you are on a boat, it will be even quieter on Eco-Mode, and should not disturb anyone in nearby. The Honda can go from 4.0 to 9.6 hours on one tank of gas, depending on the percentage of load that it is required to power at any given time. This model is an upgrade from its predecessor, which went from 1,600 running and 2,000 surge watts to 1,800 running and 2,200 surge watts in the new model.

It also has a new feature: the fuel shut-off switch, which, as previously stated, allows the carb to run dry so that no buildup occurs to interfere with the ignition in the future. Another update is the oil drain, which now has been fixed so that it no longer spills, but instead runs into the drain pan where it is supposed to go. There is also increased ventilation to avoid overheating the front panel.

The Honda EU2200i weighs 45 pounds without fuel, still light enough to carry easily thanks to the contoured handle. The plastic covering eases the movement of the machine alongside your body as you walk. One last thought: Honda has excellent customer service, readily available parts and many locations throughout the U.S.

• Extremely quiet
• Reliable technology
• Fuel shutoff allows carb to run dry
• Good warranty and customer service
• One-pull start
• No fuel gauge
• Less runtime than the competition
• Our 5 pick for the: best 2000 watt generator
• Our 3 pick for the: best honda generator
• Our 2 pick for the: best quiet generator
• Our 5 pick for the: best generator for tailgating
• Our 2 pick for the: best inverter generator

Champion Power Equipment 200961

• Peak/rated watts: 2,500/1,850 – gasoline, 2,500/1,665 – propane
• Engine: 79cc, 4-stroke, variable speed
• Fuel tank: 1.1 gals.
• Run time: 11.5 h – gasoline, 34 h – propane (25% load)
• Outlets: 120V 20A Duplex (5-20R), 12V DC Automotive, Parallel
• Noise level: 53 dB (A)
• Warranty: 3-year limited

The Champion 3400 Watt Portable Inverter Generator is the ideal combination of flexibility and convenience. This contemporary dual fuel generator can run on gasoline or gas. Fuels can be easily changed by quickly turning the gas selector knob. Once the system uses gas, its 79cc motor generates 1,850 running watts and 2,500 watts initially. Using gasoline, the generator can run for 11.5 hours out of a full tank at 25% load capacity.

On the other hand, the motor of the engine provides 1665 running watts and 2,500 starting watts if you use it with propane. The Champions Inverter technology has an advanced economy mode. This can decrease the electric load. At the same time, it allows for quieter operation, offers reduced gas costs and extended engine life. This small RV generator is also equipped with cold start technology, which ensures immediate starting once the weather is cold.

This is just one of the best portable dual gas generators running at 53 dBA. So it doesn’t emit a lot of sounds. In addition, it includes a propane hose using a fixed regulator. The Champion generator comes with a 3-year limited warranty. Plus, it includes FREE lifetime technical support.

• Runs on gas and propane
• Portable design, easy to keep and use
• Ultralight construction
• Ultra-quiet operation
• The fuel tank is small

• Peak/rated watts: 2,000/1,600
• Engine:  79.7cc 4-stroke OHV
• Runtime: 6 hrs. (50% load)
• Outlets: (2) three-prong 120V, (1) 12V DC, (1) 5V USB port
• Noise level: 50 to 55 dB(A)

The Wen 56200i is a good balance between power and price. It is lightweight enough for ease of portability, quiet enough to avoid disturbing your neighbors while camping, and offers clean power for delicate electronics.

However, it is important to know your wattage and power demands for this one, because it would have trouble exceeding its described wattage and surge start-up wattage. But if you don’t have a lot of demands for this basic generator, it is a lot lower in price for many of the same features as the higher-priced competitors. It may not last as long as, say, the Honda, but it can keep up with your day-to-day needs, as long as they are not too strenuous.

Users have tested it on campgrounds, construction sites, during power outages and tailgates. Switching to the Eco-Mode may be necessary for it to power small appliances one at a time, such as microwaves or coffee makers.

The Wen may be very similar inside to the Yamaha, but it is missing a small door, which makes an oil change a bit more difficult: you have to remove the side of the generator. Having to oil it every 24 hours might be a bit of a pain, given this little flaw. The price tends to fluctuate throughout the course of the year, so make sure you get it when it’s cheapest, around $410.00.

Pulsar G2319N

• Peak/rated watts: 2,300/1,800
• Engine: 80cc single cylinder 4-stroke OHV
• Fuel tank: 1.18 gal.
• Outlets: (2) AC 120V 13A, (1) 12V DC 8A, (1) 5V DC USB
• Noise level: 59 dB(A)
• Warranty: 1-year limited

The Pulsar G2319N offers a power output of 1,800 running and 2,300 starting watts, and 6 hours of operation at half load on 1.18 gallons of gas, which is significantly higher than some (when measured) at only 25% load. At 47 pounds, it is lighter than all but the top two, Yamaha and Honda.

At 59 dB, it is reviewed as being quiet from at least 10 feet away, so it would follow that closer up, it is not quite as quiet, similar to the Briggs-Stratton (you need to be 7 feet away). Sine wave technology allows it to be safe for charging delicate electronic devices.

It has parallel capability, so it can be used alongside another one for more power. There is a 5-volt USB outlet and cigarette lighter – this works really well with the cable included when it is used to charge batteries. There were a few issues with the pull starter – they seem to be a bit fragile and are easy to snap.

But overall this device offers a great capability at a good price. A note of caution: the manual directions could be more clear. The battery switch must always be on before you try to pull-start or the auto-choke will flood the engine. Also, in order to manually shut down the generator, you must use the auto start/stop button.

• Louder than more expensive models
• Our 7 pick for the: best 2000 watt generator
• Our 10 pick for the: best quiet generator
• Our 8 pick for the: best inverter generator
• Things to Consider

In this buying guide we have answered some common questions which can lead you through the ins and outs, frequently-asked-questions and common misconceptions which will affect your considerations when purchasing a generator.

Taking your generator to a boat: What should you consider in the first place?

A generator must be lightweight and portable enough so you can easily take it to/from your boat. You should prepare your generator for a boat. You need to make sure that there are no exposed metal or metal parts inside the generator that might rust when exposed to humid conditions or salt spray.

It is fairly easy to take the screws out and remove the plastic outer cover of the generator in order to cover the screws and hardware in rust-preventing spray paint. Use something like Bowsheild T-9 to cover the electrical parts of the generator, and high heat paint for muffler if you are concerned about moderate heat build-up in tighter spaces on the boat.

• Do you need to ground a generator on a boat? Are there generators that don’t need to be grounded?

According to the National Electrical Code 250.34 Generators-Portable. “The frame of portable generator is not required to be grounded to the earth if the generator only supplies equipment or cord-and-plug-connected equipment through receptacles mounted on the generator, or both, and [the] metal parts of the generator and the grounding terminals of the receptacles are bonded to the generator frame.”

Under conditions that are the same as the NEC, OSHA directs (29 CFR 1926.404(f)(3)(i)) that “the frame of a portable generator need not be grounded (connected to earth) and that the frame may serve as the ground (in place of the earth).”

• What will you power on a boat?

If you want to power some simple things like hair dryer, electronics, and small devices like a coffee maker or microwave, or even a dishwasher on your boat, then a small portable inverter generator should be more than enough to meet your power needs, like for a example Wen model, which is also considered to be one of the best Wen generators .

However, if you must have air conditioning or appliances that suck up a lot of power in a short time, like a fridge/freezer, then you might as well consider going with a traditional, more permanent marine generator.

The generator you choose must have enough power capacity and the correct outlets for the specific devices you have, and the combined wattage to power them, concurrently if necessary. Many inverter generators have more than one mode, so they can be used to power a greater or lesser load at different times, without compromising the integrity of the output. Most also have eco-modes to reduce the RPMs to save gas while powering smaller loads.

• Conventional vs. Inverter Generator

An inverter, on the other hand, draws power from a fixed DC source (i.e.: battery) and inverts the power into usable (most likely 120V) AC current.

Inverter generators combine the best of both worlds through the use of advanced electronics. They combine the technologies of both traditional generators and traditional inverters to first generate AC current, which is converted to DC, then inverted back to AC power in a pure sine wave that will not fluctuate and cause problems for its users.

And please don’t forget the option of the portable power station , which will be also suitable and less noisy, especially for shorter trips.

• How long do you need a generator to operate?

You must calculate the amount of time which you need the generator to run and then compare this with the generators which are listed here. They have different runtimes and fuel capacities. In addition, certain fuels have better economy than others.

Propane powered generators don’t get as far on the same amount of fuel because unfortunately, propane has less potential energy in its raw form than either gasoline or diesel.

From Wikipedia, “propane is capable of producing 84,300 BTU’s per gallon, gasoline is capable of producing 114,000 BTU’s per gallon, and diesel is capable of producing 129,500 BTU’s per gallon. In layman’s terms, 26% more propane is needed to produce the same amount of energy as 1 gallon of gasoline.”

Accordingly, 35% more propane is needed to produce the same amount of energy as 1 gallon of diesel, as it is in case of the best diesel generator . A converted Honda EU2000i generator could use a 20–30-pound propane tank.

The generator specs given in this article can be used to determine average times that the given generators will run on a partial load. It follows that if the load is increased, the runtime will decrease accordingly.

If you need to run a lot of appliances on your generator for a longer time, it may be worth it to invest in one of the more expensive, longer-lasting generators such as the Honda or Yamaha . Or you could try the Champion , which is more budget-friendly.

• How noisy is a generator?

The design of a generator has more to do with noise level than the fuel used to power it. It is helpful to check the noise rating (and the fine print included there) to determine just how noisy or quiet a generator will be.

Some generators will be noisier because their rating was determined from 7 to 10 feet away, whereas the noise level of others was tested whilst standing right next to it. Most of the inverter generators that we have reviewed here were created to be less noisy (or around the same) as a normal conversation or the quiet hum of a coffee shop.

Check how far away from the generator it was tested to determine how close you can be to enjoy this lower noise level.

Keep in mind that small, portable inverter generators that are reviewed here are specifically designed to be quieter than the larger, traditional varieties. This can be a good thing if you are going to be in closer proximity with other people, or of higher levels of noise will bother you.

Safety considerations

Safety is important, especially when you’re on board. Let’s have a look at the safety features that are essential in a marine generator and a couple of things that can add to your protection while using a generator.

• Low oil shutoff

Look for a generator with this feature that will shut itself down in the event of a possible overheating situation that could wreck it.

• Emergency stop button

Some generators have this feature included already; with others, you may need to buy an emergency stop button kit and install it yourself.

A delicate sensor is placed on the outgoing power source which monitors the amount of power leaving it. If the power surges for any reason, the power source cuts itself off, possibly saving your life, or the life of someone you love.

• Fire extinguisher

It is common sense to have a fire extinguisher on your boat, but doubly so if you have a portable generator with an independent motor creating heat and exhaust. There is a lot of energy and electricity being contained within a small area, and sometimes the unexpected can happen.

• Carbon monoxide detectors

Make sure you have at least one, probably even two carbon monoxide detectors located in the cabin of your boat in case the generator’s fumes incidentally end up in your living space. Follow the manufacturer instructions, talk to friends and experts, and read the following guidelines on safely placing and installing a portable inverter generator on your marine vessel.

• Tips and tricks

Installation

• always follow the manufacturer’s instructions
• place the generator on a flat surface that is free of debris, non-combustible and non-conducting
• Ensure adequate ventilation around the generator
• Direct emissions away from inhabited areas

Maintenance

• Turn off unit before dismantling or servicing
• Cover and insulate electrical surfaces
• Drain all carb before storage
• Don’t smoke near the generator
• Inspect all parts regularly: on a quarterly, six-month and yearly schedule
• Use your generator on a regular basis
• Don’t allow unused fuel to sit inside the generator
• Keep a fire extinguisher nearby

• Do I need to ground a generator on a boat?

Grounding rules state that you do not have to ground your generator if it only powers things that are plugged in through “electrical receptacles,” and the metal parts of the generator are connected to the generator’s frame, which serves as a “ground,” in place of the earth.

• Where do I better place a portable generator on my boat?

More than one is better, in case one fails. Ventilation is a serious issue on boats, since wind can blow even well-vented, properly directed fumes back over the boat or into the windows. You could also put it on the bow pulpit, but you must make sure the hatches are closed in this case.

• Do I need to protect a generator from water when using on a boat?

You should also cover the electrical parts with some type of protective covering and never take the cover off or service it while it is either turned on, in contact with water or connected to a source of power. These are reasonable precautions to take if you wish to avoid getting an electric shock. In addition, you should protect the metal parts with rust-protective coating.

Always follow all the instructions on the manufacturer’s manual.

• Our verdict

Out of all the generators we reviewed, the first, second and thirds spots went to the Briggs & Stratton P2200, the Honda EU2200i and the Westinghouse iGen2500, respectively.

The Briggs & Stratton P2200 was the all-round winner, since it it is an affordable model and scored so high in the most categories, including: one of the longest running, ease of start, PowerSmart mode, dual capability, noise level and good warranty length.

The Honda EU2200i came in second place, having almost identical performance and features. The second placing was mostly because of a slightly smaller fuel tank capacity.

Third place was awarded to the Champion Power Equipment 200961 . This model seems to give a lot for a little, having the highest surge watt rating of all the of the competitors. It also has up to 10 hours of continuous runtime on one gallon of fuel.

• Do not let the generator get wet
• Do not use the generator whilst the boat is in motion

What is the difference between a marine generator and a generator?

The main difference between a marine generator and an ordinary residential or industrial generator is that the former is designed to withstand moisture and corrosion. 

Along with that, marine generators typically do not need a self-contained cooling system as they are cooled by hydraulic pumps. As such, they are significantly smaller than a typical generator.

What size generator do I need to run AC on a boat?

As a general rule of thumb, you should find the necessary “starting” wattage needed to operate the AC unit. Following that, you should divide it by 12 volts to get amps. From there, you will need to search for a generator that meets this requirement.  

What is the smallest marine generator?

The smallest marine generator in this list is the Jackery Portable Power Station Explorer 240. In terms of size, its dimensions are 9.05 x 5.24 x 7.87in, and it only weighs 3 kg. This makes it one of the best options for lightweight, portable marine generators on the market.

When looking for the best generator for a boat, there are many good options to choose from. However, at the end of the day, it depends solely on what you are looking for.

Are you looking for something big and powerful, or something smaller which would be easier to transport?

The most important thing when looking for a generator is making sure that it fits all of your individual requirements. Past that, the world is your oyster!

Wind generators – buyers’ guide

After a flurry of recent technological developments, Duncan Kent compares the latest high-output wind turbines

Three-bladed rotors have become increasingly popular. Although early models were quite noisy, smart CAD-designed blades have considerably reduced the thrumming and whistling sounds by removing the turbulence around the blade tips. Furthermore, the use of more efficient, low-cogging (less initial friction) permanent-magnet alternators has also allowed blade speeds to be reduced, further limiting ambient noise levels.

AIRBREEZE £1,169.50

The Airbreeze is easy to assemble as everything is contained within the casing, requiring only a quick blade assembly before being ready to mount. It’s not the most powerful and can be a little noisy in high winds, but it’s very good value as you don’t need to spend money and time installing an external charge controller.

Verdict: Easy to assemble, mount and operate, but noisier and less powerful than some

ecopowershop.com

ECLECTIC ENERGY D400 £1,350

Although it’s fairly straightforward to assemble, it’s not made any easier by the sheer weight of the generator.

During previous trials it proved to be one of the quietest on test, started quickly and outputting an increasingly progressive rate of charge. It is also less prone to yaw from side to side than some, keeping head into wind to ensure a more stable output.

Provided its mounting can handle the loads, its sturdy build allows it to continue operating in very high winds, producing a staggering 50A+.

Verdict: Solidly engineered, very powerful and quiet. The flip side is it’s heavy and needs dump resistors

eclectic-energy.co.uk

LEADING EDGE LE-300 £649.95

The device is easy to assemble and light enough to carry in one hand. An integral rectifier produces a two-wire DC output and its efficiency has recently been improved with the fitting of stainless steel counterweights to offset the effects of pitching and yawing common on a yacht.

A run/stop switch is supplied that brakes the turbine by shorting its output. It can also be supplied with a dump load style regulator to prevent overcharging (£189.95).

The LE-300 is probably the quietest of all the three-blade models available, but it’s also one of the least powerful.

Verdict: Light and great value, but with a lower output than many of the others

leturbines.com

LEADING EDGE LE-450 £899.95

The alternator uses rare earth fixed magnets and has zero ‘cogging’, allowing the turbine to start quickly and to spin in the lightest of breezes. Furthermore, having five blades of advanced design allows the swing radius to be kept to a minimum and reduces wind noise noticeably, while its light weight allows it to be safely mounted on a mizzen mast or possibly even a stout spreader.

Verdict: Well designed, lightweight and good value, but needs manual tethering in over 35kt of wind

RUTLAND 914i £649.96

An optional multi-stage charge regulator is available, which has an on/off switch and LED charge status indictors. It can also accept and integrate solar panels up to 160W.

The surprisingly cheap HRSi regulator (£78.50) works electronically to gradually slow the turbine in high winds or near full charge situations, rather than using resistive dump loads.

The 914 is quiet in operation and quick to start generating in light winds. Well made, its heavy metal hub acts as a flywheel, giving it enough momentum to smooth out the pauses during brief lulls in the wind.

Verdict: Quiet and inexpensive, with a smart controller. Relatively low output

marlec.co.uk

RUTLAND 1200 £1,195.00

High rotation speeds and efficient alternator design results in plenty of raw power. Marlec’s latest smart HRDi charge controller (£155.95) continuously alters the rotation speed of the generator, slowing it down as the batteries become more charged. It also incorporates the latest Maximum Power Point Tracking (MPPT) technology to optimise all the available energy produced and Pulse Width Modulation (PWM), which enables multi-stage charging to keep the batteries topped up. Other features include dual-battery bank control, an input for up to 250W of solar panels and an optional remote digital display.

Verdict: Powerful, well-made and with smart regulation. Has a wide rotation diameter

SILENTWIND 400 £1,291.33

The Silentwind is heavier than it first looks, mainly due to its high output, permanent magnet 420W alternator. Recent (2016) upgrades include a boost feature in the generator and a lower start speed thanks to its ‘low cogging’ design.

Available in 12V, 24V and 48V versions, its three-wire AC output connects directly to a recently upgraded smart charge controller with solar inputs, an LCD display, integral brake switch and Bluetooth connectivity so the user can monitor their battery status and charge from a mobile device or laptop. Furthermore, the new controller (£410.42) now consumes only 20mA itself, rather than the 100mA of the old model.

Verdict:   High power output and a nifty Bluetooth smart controller, but all at a price

technicalmarinesupplies.co.uk

SUPERWIND 350 £1,528.75

The SCR Marine charge controller option (£384) has two independent outputs, for start and service banks, although it does rely on the rather crude method of dumping any excess loads to two large resistors, which can get very hot if the device is left running in a gale.

Despite having a slightly lower output alternator than some, in field tests this device gave a very respectable performance in wind up to 15 knots, and provided serious amps in higher winds up to 28 knots.

Verdict: Light, well made, quiet and powerful, but expensive and reliant on dump load regulation

The 4 Best Small Boat Generators To Empower Your Sailing

Like any other equipment, boating enthusiasts need a reliable small generator to keep their gear charged. The right size and type of small boat generator  will depend on the appliances you plan to use and for how long. For example, any small portable generator would work great to charge a sound system or a mini cooler.

Jackery is one of the leading solar product manufacturers that has been in the portable generator business for 11 years since 2012. Many small Jackery Solar Generators available in the market are great choices for boat owners. The most compact Jackery Solar Generator 300 Plus has a battery capacity of 288Wh that can charge most small appliances on the boat.

Can A Small Generator Power Your Boat?

Yes, a small generator for boats  is an excellent choice for powering a wide range of appliances on a boat. These electric devices can include anything from GPS mapping systems to mini coolers and even smartphones.

A small boat generator  is usually powered by gasoline or diesel to produce energy, which is then converted to electrical energy to charge appliances. Over the last few years, solar generators have been another popular charging solution for boat appliances.

Boat or marine generators  are important for boats as they provide steady electricity to charge audio systems, lights, refrigerators, and more. Only a small boat generator can make the difference between being lost in the sea and making it safe like home.

What Are The Types of Small Generators for Boats?

When choosing the best small generators for boats, you'll need to understand the different fuel types — gasoline, diesel, and solar. Each fuel type has its advantages, but you'll see a few disadvantages that can ultimately affect the purchase of a generator.

Among all the fuel types available out there, solar generators are relatively more popular. They are portable, quiet, and easy-to-use charging solutions when you're out in the water. Jackery Solar Generators  are compact in size and can charge most boat appliances throughout your sailing journey.

How Does A Small Boat Generator Work?

The working of a small boat generator  will depend on the fuel type — gasoline, diesel, or solar. For example, gasoline or diesel generators convert fuel energy into electricity. On the other hand, solar generators combine a battery backup and solar panels.

The Jackery SolarSaga Solar Panels  consist of highly efficient monocrystalline silicon cells that collect maximum sun rays that fall on them. The DC electricity generated is converted to usable AC electricity with the help of a pure sine wave inverter.

All the generated AC electricity is stored in the Jackery Explorer Portable Power Stations , which can then be supplied to the electrical appliances.

What Size of Small Boat Generator Do You Need?

In the daily navigation on a boat, there's no means to charge the appliances — and that's where the need for a small boat generator  arises. The exact size of the solar generator  will depend on the number of appliances you plan to use and their running hours. In the navigation mode, the average electrical consumption is around 92 Ah and 1110 Wh.

Source: The energetic balance and the electric needs of sailboat  

Let's take the example of Jackery Solar Generators to understand better.

Suppose you are charging a few lights (50W), a fridge (42W), a sounder (12W), and a TV (48W) using Jackery Solar Generator 700 Plus.

The working time will be as follows:

Working Time = Capacity in Wh × 0.85 / Operating wattage of the appliances

Working Time = 680Wh × 0.85 / 152W = 3.8H.

Adding a Generator to a Boat

• By Lenny Rudow
• November 14, 2023

Boating in homelike comfort for more than a few hours at a time takes more electricity than most battery systems can provide, but adding a generator to the mix gives boaters a constant feed of power. A generator is a rather involved upgrade, but it can be boiled down to a few basic steps.

Determine Your Vessel’s Power Needs

There’s a big difference between the power requirements of a 40-foot cruiser and a 30-footer. Take air conditioning, for example. Both boats may have it, but one might need a 20,000-Btu system to chill down the salon while the other can get by with 5,000 Btus. So, the bigger boat will not only have more systems to feed, but each one is larger in scale. That means step one is simply figuring out how much power is enough. And remember that bigger isn’t always better. Generators are designed to run under load, and if you regularly run one at less than 25 percent of its output and don’t typically run at closer to 50 to 70 percent of load, it will often lead to soot formation, poor piston-ring seals and clogged injector tips.

What if you need only minimal juice? In that case, could carrying a portable generator aboard make sense? Maybe so, but these usually hold enough fuel to run for just eight or nine hours. If you want electricity for longer than that, you’ll have to carry a gas can and plan to refuel from the deck of a pitching, rolling boat. Obviously, that raises safety concerns. Plus, these generators generally aren’t marinized for use in the saltwater environment. As a general rule of thumb, carry-on generators have limited applications on boats.

Determine Your Boat’s Available Real Estate

The biggest limiting factor in how much power you can bring aboard will be engine-room space. Generators are often shoe-horned in, which makes for tough maintenance, but even tougher installation. You need a solid, level mounting surface, as well as room for cables and hoses. Also consider access to the area, because it won’t do you much good to buy a generator only to discover it doesn’t fit through the hatch.

Mounting a Boat Generator

Generators are weighty, and they require secure mounting. Screws or lag bolts aren’t sufficient—you need stout through-bolts or hefty brackets. Think of it like mounting an engine in a boat, because, well, they are engines. True, the generator won’t be bearing any thrust, but all that weight creates an awful lot of leverage when the boat rocks and rolls. If you’re adding a generator to a boat that originally offered one as optional equipment, check with the manufacturer to see if pre-tapped mounting plates were laminated into the stringers. You may have an ideal mounting point ready and waiting for you.

Plumbing a Boat Generator

Ready to start running hoses? You’ll need a cooling water feed via a through-hull with a seacock, and an exhaust run. Intake lines need to have a sea strainer between the seacock and the generator, and should not depend on a scoop-style through-hull, which can force water into the generator when it’s not in operation. Exhaust lines need an anti-siphon loop installed at the manufacturer’s recommended minimum height above the waterline.

Obviously, you’ll also need to get fuel to the generator. In the interest of minimizing the hazard of mixing up fuels and increasing the workload, most boaters want to choose a generator that burns the same fuel as their vessel’s powerplants and tap into the existing supply. Otherwise, installing a fill and vent lines will be necessary in addition to installing the tank itself. You’ll also need to plumb in a fuel filter between the tank and the generator.

Wiring a Boat Generator

Wiring is a stage that can get quite tricky, and the bottom line is that you must follow the manufacturer’s specifications for both the boat and the generator. That said, there will usually be cables for an externally mounted battery for starting the generator, the AC output, and you may wire in a remote-control panel above decks, as well. Care must be taken to make sure that all wiring is up to manufacturer and ABYC specs, and that it’s supported and protected from stress and chaffing. AC wiring must be done as per the manufacturer’s recommendations. Note that generators must also be grounded and bonded in accordance with USCG regulations.

Insulating a Boat Generator

Generators can be notoriously loud. If your boat’s engine room isn’t thoroughly insulated, choosing a generator contained in an insulated soundshield is a smart move. Adding acoustic insulation to an engine room after the fact is rarely as effective. Air intakes, exhaust type and mounting will also have an impact on the noise and vibration levels.

So, is adding a generator to a boat really all that involved? You bet it is, which is why few DIY boaters ever even consider giving it a shot. It’s also risky to try installing one yourself from both a safety and a reliability/longevity standpoint. So, 99 times out of 100 this is a job best left to the professionals.

Shore Power vs. Generator Power: Which Is Best?

When it comes to powering your boat, there are two main viable options: shore power, or an onboard generator. While both offer unique benefits it is the superior choice for most boaters. Having a dependable, cost-effective, and eco-friendly power source is essential. That’s why we recommend shore power through our high-quality power pedestals. Let’s explore why shore power is the better option.

What Is Shore Power?

Shore power connects your boat to a marina’s electrical system through a power pedestal . By plugging into the marina’s grid, you can run your boat’s electrical systems without the need for onboard generators or batteries.

Why Power Pedestals Are the Better Solution

Our power pedestals are designed to provide seamless shore power connections. This ensures that your boat is powered efficiently and safely. With their durable design and customizable options, our power pedestals allow you to enjoy all the benefits of shore power without the hassle of managing generators or fuel. They also come equipped with additional features like water hookups and lighting to enhance your marina experience.

What Is Generator Power?

Generator power involves using an onboard or portable generator to produce electricity independently of shore facilities. While generators offer flexibility, they come with significant drawbacks. This is especially true when compared to shore power.

Advantages of Generator Power:

• Flexibility : Generators can be used in remote locations where shore power isn’t available.
• High Power Output : Generators can meet high energy demands, making them useful for large vessels or extensive electrical needs.

Why Shore Power Outshines Generator Power

If generators are more powerful and more flexible, why choose power pedestals over them? There are three main reasons why shore power is the clear choice for most boaters. Their cost efficiency, reliability, and environmental friendliness let them stand apart from their competition. Let’s talk more about these attributes.

• Cost Efficiency:

Shore power is far more economical in the long run. You eliminate fuel costs, maintenance fees, and the need for constant repairs that come with generator use. Power pedestals offer a straightforward, affordable connection to the marina’s power grid. All you need to do is pay a small fee to have access to the equipment. All of the maintenance is their responsibility.

• Convenience and Reliability:

Power pedestals provide a steady, reliable source of power. Unlike generators, which can run out of fuel or break down, shore power through power pedestals ensures that your boat is always powered without extra effort. Like gas stations, all you need to do when your power is running low is find a place to charge up. Most marinas across the country have the hookups you need, so it’s a dependable way to have power.

• Environmental Responsibility:

Shore power produces fewer emissions than generators, making it the greener choice. By plugging into marina power pedestals, you reduce both air pollution and noise.

There is one thing to consider: shore power is only available at marinas equipped with electrical hookups. If you venture into remote areas, it may not be accessible. But for the average boater, this shouldn’t be an issue.

Why Choose Dock Boxes Power Pedestals?

Our power pedestals are durable, reliable, and easy to use. Whether you’re outfitting a small dock or a large marina, our power pedestals offer the perfect shore power solution. With customizable options, you can ensure that your setup meets your specific needs. Our pedestals provide safe and secure connections to the marina’s electrical grid. That way, you and your guests have peace of mind as you enjoy your time on the water.

Shore Power Is the Clear Winner

When comparing shore power and generator power, the advantages of shore power are undeniable. From cost savings to environmental benefits, shore power with our power pedestals offers boaters a more reliable, eco-friendly, and convenient solution.

This helps to keep your various electronic devices charged, which can boost your safety and your quality of life on the open water.

However, finding a good generator is often easier said than done. If you’re not careful, you might end up with a low-quality generator that can’t keep up with your different devices. And what’s the point of a portable generator if you can’t trust its power and performance?

To help you find the best generator, we’ve put together reviews of some of the best generators on the market. Between our reviews and our buyer’s guide, finding the best generator will be easier than ever!

A Quick Comparison of Our Favorites

The 10 Best Portable Generators for Boat Use – Reviews 2024

1. wen 56200i portable inverter generator – best overall.

Chances are that you want to get back on the boat as quickly as possible. In that case, let’s cut to the chase: if you’re looking for the best overall portable generator , the WEN 56200i Portable Inverter Generator is our top choice.

We love the versatility of this generator. With the 5V USB port, 12V DC receptacle, and two 3-prong 120V receptacles, you can power just about anything. Speaking of power, you get a lot with the 79.7 cc four-stroke engine than can provide up to 2,000 surge watts and up to 1,600 rated watts, all while keeping you compliant with EPA III and CARB regulations.

Honestly, the only real issue with this generator is the height. At 18 inches, this may be a bit too tall for certain boats but it is still the best portable battery generator for boats we have reviewed this year.

• Versatile receptacles and ports
• Powerful engine
• EPA III and CARB compliant
• A bit too tall

2. Rockpals WCE001 Portable Generator – Best Value

It’s an open secret that boating is a very expensive hobby. It’s good to save money whenever and wherever you can. And if you’re looking for the best portable generators for boat use for the money, then you can’t go wrong with the Rockpals WCE001 Portable Generator .

At only 5.5 pounds, this item puts the “portable” back in “portable generator.” And you can charge plenty of items thanks to four DC 12-volt ports, two AC outputs, and two 5-volt USB ports. Your gear will be especially safe thanks to the short-circuit and overcharged protection on top of the built-in temperature control.

So, what keeps this from being our “best overall” choice? This generator sometimes has trouble charging Apple products. And you can’t always run items while you charge them, which is bad if you were hoping to use your smartphone while it charged. Despite this we think its the best value boat generator on the market.

• Lightweight
• Short-circuit and overcharge protection
• Temperature control
• May not charge Apple products
• You may not be able to charge and use items at the same time

3. Honda EU2200i Portable Inverter Generator – Premium Choice

Sometimes, you want the best brand names that money can buy. Are you on the lookout for a truly premium brand of portable generator? In that case, we recommend the Honda EU2200i Portable Inverter Generator .

This is a surprisingly quiet generator, typically running between 48 to 57 dBA, although some users dispute this (see more below). And you get plenty of power thanks to 2,200 watts. If you need more power, you can actually use a special cable to attach two of these generators. Finally, we loved the fuel efficiency: a single gas of tank can get you 4.0 to 9.6 hours of use depending on the power load involved.

However, this premium choice isn’t perfect. In this case, several users reported that it is louder than advertised. And you may need to buy a separate funnel to pour engine oil without making a mess.

• Quiet design
• Can double power with a second generator
• Fuel-efficient
• Too noisy for some users
• Separate funnel may be required

4. Durostar DS4000S Portable Generator

The Durostar DS4000S Portable Generator did not manage to crack our “top three” for portable generators. Nonetheless, this a solid model that is suitable for many of your boating needs.

With its 4,000 peak watts and 3,300 running watts, you get a lot of power from the 208cc OHV engine. You get several outlets here, including two 120V household outlets and a single 20V 30A twist lock outlet. The fuel capacity (3.96 gallons) is pretty solid and the entire thing is EPA and CARB compliant.

What’s the catch? Some users report that the fuel gauge isn’t very accurate. And others report that the pull-start mechanism can be difficult to get started.

• Strong power
• Versatile outlets
• Good fuel capacity
• Compliant design
• Inaccurate fuel gauge
• Difficult pull-start mechanism

5. A-iPower SUA2000iV Portable Inverter Generator

The A-iPower SUA2000iV Portable Inverter Generator was very nearly our choice for best premium portable generator. And depending on your needs, this particular generator may be a perfect pick for your next boating adventure.

The generator puts out 2,000 peak watts and 1,600 running watts which is good (though not great). You have plenty of power options thanks to the two 120-volt outlets as well as the 12-volt multi-function port. At 50% load, you can look forward to 9 hours of runtime, all while enjoying features such as built-in fuel gauge, indicator lights, and overload alarm.

As usual, there are a few downsides you should be aware of. As with most gas-powered generators, this is going to require more maintenance than a fully electrical model. And at 50 pounds, this might be a tad too heavy for service as a portable generator (though we liked the handles).

• Good power output
• Multiple outlets and port
• Good runtime
• Extra features like fuel gauge and indicator lights
• Extra maintenance required

6. Flashfish Portable Power Station

Still on the lookout for a good budget portable power generator? In that case, the Flashfish Portable Power Station may be worth a closer look.

On top of its solid price, this generator provides a reliable 150 watts of sine wave output. And at only 4.5 pounds, this portable generator is truly compact. And there are many power output options, including two 12-volt DC ports, two 110-volt AC outlets, and three USB ports (including two designed for double-speed quick charging). Finally, the LED screen is a perfect way to keep an eye on your generator’s power and the power of your attached devices.

What’s not to love? According to some users, it is difficult to return this product if it should malfunction. And some of the cooler accessories (like a solar panel to help recharge the generator) are sold separately.

• Sine wave output
• Lightweight and compact
• Multiple power output options
• Convenient LED screen
• Difficult to return
• Better accessories are sold separately

7. Yamaha EF2000iSv2 Portable Generator

The Yamaha EF2000iSv2 Portable Generator is not as good as many of the models we tried. But it’s not nearly the worst. Ultimately, this portable generator is strictly “middle of the road” in terms of quality and features.

There were some things we liked, including the 2,000-watt AC output and the quiet muffler that brings the noise down as low as 51.5 dBA when you’re operating at 25% load. It’s also CARB compliant, but there are a few things you need to watch out for.

Specifically, the oil spout is very difficult to access. This alone makes the oil very difficult to fill. And the generator must ideally be level during use–not a great option when you’re out on the water!

• Decent power
• Quiet operation
• CARB compliant
• Oil spout difficult to reach
• Must be level for optimal use
• Difficult to fill the oil

8. Rainier R2200i Portable Inverter Generator

When it comes to our review roundup, there are always winners and losers. Unfortunately, the Rainier R2200i Portable Inverter Generator falls firmly in the “loser” category.

There are some things to like, including the 2,200 peak watts. You can get up to 13 hours of runtime from the 1.3-gallon fuel tank, and it’s pretty quiet (as low as 52dBA). But there are quite a few issues to contend with.

The instruction manual is confusing and sometimes references other generators that don’t exist. Additionally, it comes with nothing to help you check the oil levels or keep track of service intervals. Finally, some users report the manufacturer is slow to respond to customer concerns.

• Bad instructions
• No way to check oil out of the box
• No way to track service intervals
• Bad customer service

9. Generac 6866 iQ2000 Inverter Generator

The Generac 6866 iQ2000 Inverter Generator is one of the most expensive generators on our list. You might expect solid performance and features for this price. Unfortunately, you may end up very disappointed!

The max AC output of 2,000 watts is good, if not great. And we liked the intuitive features such as the PowerBar and PowerDial. But many other features disappoint, especially at this price point.

Some users received generators that were broken or otherwise missing parts. The engine tends to sputter, and you can really smell the exhaust. Finally, it tends to stall out during use, especially prolonged use.

• Convenient PowerVar and PowerDial
• May arrive damaged or broken
• Engine sputters
• Prone to stalling out

10. AIPER Portable Power Station

The AIPER Portable Power Station sits at the bottom of our list. Unfortunately, that’s not a coincidence: this is one of the worst portable generators for boating.

As usual, there were a few things we liked. That includes the lightweight (3.86 pounds) design and the 12-month “worry-free” warranty. But much of what is good about this generator is outweighed by its negative qualities.

The charge rate from the lithium-ion battery is fairly slow. And it shuts off after about 15 seconds of inactivity, which can be fairly annoying depending on the situation. On top of that, the LCD screen is quite fragile and the company offers poor customer service.

• Good warranty
• Slow charge rate
• Shuts off too quickly
• Fragile LCD screen

Buyer’s Guide – Choosing the Best Portable Generators for Boat Use

Thanks to our reviews, you might already be ready to snag the portable generator of your dreams. However, you may still have a few burning questions. And we’re here to answer those questions as part of our in-depth buyer’s guide.

Whether this is your first generator or you are a generator veteran, this buyer’s guide will help answer your biggest questions. And once you’ve completed this guide, all that is left to do is hit that “order” button and wait for your new portable generator to arrive!

Preparing Your Generator

You might have used a portable generator for other hobbies such as camping. If that’s the case, you might imagine that a portable generator for your boat is a real “plug and play” affair. In reality, there are a number of factors you need to consider when preparing your generator.

The biggest step is “marinizing” the generator. Don’t worry: that’s just a fancy word for making sure your generator is more suited for use on the water. For example, if you’ll be operating in cold conditions, you may want to put lanocote or Tefgel on your fastener threads to keep them from freezing over.

Additionally, you may want to cover the generator exhaust area in rust-resistant, high-heat paint. This ensures that it will still look good after a few years of use.

The final step to marinizing your generator is putting some kind of soft seal on everything except the muffler. This helps to provide an additional layer of protection (quite literally) on the generator so that it can withstand almost any conditions.

Mounting the Generator

Shakespeare’s Hamlet famously asked himself, “to be or not to be?” But before you go boating, you need to ask yourself a bigger question: to mount or not to mount?

On paper, the whole purpose of a “portable” generator is that it’s…well…portable. Nonetheless, you might have an easier time accessing and using this generator if it is mounted in some way.

Generally speaking, we don’t recommend permanently mounting the generator. Instead, you can non-permanently mount it to the deck for ease of access. Ideally, you should mount it in such a way that you minimize your exposure to any unwanted exhaust.

When you’re done with the boating excursion, simply put the generator into storage. For more tips on how to do this, check out our storage recommendations below.

Grounding Your Generator

Some generators are designed to be grounded to the earth before you use them. You might think there is no way to use such a generator on a boat. But with a little ingenuity, you can make it happen!

If your boat needs this kind of grounding, you can simply plug it into a shore power connection on the boat. Before doing so, though, you need to make sure that both the generator and the boat in question support this feature.

For maximum ease of use, you can simply snag a generator that doesn’t require grounding. And that’s a good example of a feature that may well be worth paying a few extra bucks for!

Fuel Considerations

Some portable generators run off of fuel. While this is a great way to provide additional power to the generator, it does bring a few major safety concerns for you to consider.

• Never refuel your generator on the boat . In the event of an accident, you could cause serious damage to your boat, your body, or both. To minimize the chances of unwanted ignition, you can simply refuel the generator outside of your boat. This is easy enough considering that these things are portable!
• Avoid using the generator in an enclosed space . When the generator is fueled up, you can technically run it anywhere on the boat. But some areas are more dangerous than others. If you use the generator near doors, hatches, windows, or vents, you might accidentally fill the cabin with carbon monoxide. And while a good carbon monoxide detector can mitigate this risk, it’s good to play things safe from the beginning.
• For added safety, be sure to inspect your generator for leaks before taking it out on the water . And make sure that you and all of your passengers understand the symptoms of carbon monoxide poisoning in the event that your detectors are faulty.

Safe Storage

A portable generator is great for a day or night out on the boat, but the generator was never designed to stay on the boat. When you’re not using it, you must keep the generator in storage. And there are a few safety tips you need to follow when doing so.

Place the generator in a locker, and make sure the locker has been drained beforehand. Additionally, the locker should be free of any other anchors, tools, mooring pins, and especially fuel. If you put the generator in a locker crowded with these items, then all it takes is a single spark to start a catastrophic fire.

One of the goals of this storage method is to protect your generator from moisture when it’s not in use. But you can take a few easy steps to protect the generator during use as well. This includes building cowling to protect the generator from the water and using rubber mounts for additional protection.

Getting Enough Power

One topic that our reviews frequently touched on was the power output of the different generators. But do you know why this output is so important and how to identify the amount of power that you really need?

It all comes down, of course, to what you are trying to power. If you mostly want to charge phones, tablets, and computers, then a generator with an output of anywhere between 1,600 and 1,800 watts should do the trick. But if you’re hoping to power something larger (like major appliances), you may want a generator with an output of at least 2,200 watts.

While we’re at it, don’t forget a simple rule: all of those little devices add up. While a single phone or laptop doesn’t require much juice, attaching several items to your generator all at once will create a larger drain on your power. If you expect to plug in many different items all at once, it’s safest to go with something that has enough power.

Better to have too much power and not need it than to need extra power and not have it!

Ready to buy your next portable generator for boat use? We hope that our reviews and our buyer’s guide has made your decision easier. If you’re still on the fence, though, we may be able to help you out by answering a final question: which were the generators that we liked the best?

When it comes to the best overall choice, we went with the WEN 56200i Portable Inverter Generator . It’s perfect for your next boat outing, and is also a real game-changer when it comes to camping.

Are you boating on a budget? The Rockpals WCE001 Portable Generator is a great choice for any budget, and it performs as well as many more expensive options.

But just as different boats call out to different handymen, different generators may be more suitable to your needs. Only you can decide which generator will help power your next outing. But between our reviews and our buyer’s guide, you can rest assured that you’ll ultimately make the right choice!
