Looking for Bluewater Trimaran plans 40-50 feet

Discussion in ' Boat Design ' started by Schoolbus , Feb 17, 2019 .

Schoolbus Junior Member

There seems to be a real gap of trimaran plans out there in the 40- 50 foot range- I am only finding trailerable tris, or very old Piver type designs, or the 54 foot Chris White Hammerhead..... Anyone out there know of any bluewater 40-50 foot Trimaran plans? (Neel 45 is one of the few production ones, and it is more of a catamaran style.......) Sincerely, Schoolbus

In WoodenBoat Magazine #265 * ( Nov . /Dec . 2018 ) was a design concept for a LOA 39' 4" ( 12 m ) wind - solar - electric trimaran motorsailer by Laurie McGowan . * Table of Contents PDF ​ ​ ( the flickering in the above animation, below the bottom in center view, is the lines of the bow centerboard and the mid centerboard and the rudder interfering with each other while being raised and lowered ) — two Elco EP-14s electric motors, one up and one down in this aft view — ​  

F-39 Farrier is close but a bit short and the retractable amas put it into the trailerable slot, I am really looking for a dedicated bluewater cruiser tri....... Something about the WoodenBoat's tri seems a bit off.....cant put my finger on it- a bit like a Popular Mechanic quality of execution..... Schoolbus

There are Grainger Tri's - about four models TR52 Performance Trimaran https://www.graingerdesigns.net/trimaran-designs/tr52-trimaran/  

Philippe Briand has designed the Exception 52 Tri, several were built by Techni Yachts Pinta in the 1980's , here's one for sale , don't know if Philippe sells plans for it though, but if meant for single handed self build then such projects are gonna be to big I think.

here is a good one.  

At 60' she's out of range, she's an tarted up for hollywood older version of an ORMA 60 ... Same type , the old ORMA 60 Brossard , she was wrecked in 2009 in Oman , and has been there like pictured for quite a number of years .  

I always thought that the big harpoon in the front would have been super useful. Would have added a lot to the marina charges though.

Creative Boats for Home Builders

Category archives: plywood trimarans, back bay sit on top kayak, a modular system approach to sot kayak sailing, paddling  and mirage drive propulsion.

Sit-On-Top (SOT) kayaks are easy boats on which to learn to paddle. They have none of the “get in the coffin and you are about to drown” psychological identity that one finds in the Sit-Inside boats and they’re amazingly adaptable to a wide range of paddling activities. It also doesn’t hurt that they are pretty straightforward boats to rotomold, which makes them very cheap to produce in large numbers.

I didn’t envision just one boat for this niche in the home-built kayak market. Instead, it came to me that there would need to be at least three models that could address the wide-ranging styles of boating interests in this area of the kayak world. The result was a couple of very clean, SOT models at 14’ and 16’ called the Corona and the Back Bay, respectively. The third model was going to be called the Wahoo, as it was specifically designed for the folks who spend a lot of time fishing with their SOT’s. I’ll get to the Wahoo in the next article.

As a canoe and kayak sailor and a guy who had just been out for a test drive on the Hobie Adventure Island, which is based on their 16’ SOT Adventure model, I wanted to offer my own take on what makes for a truly fun and stylish, sailing SOT kayak. The result was that a fully integrated system of component parts was designed for the basic Back Bay. This modular approach allows the Back Bay to go sailing by simply adding a system of light-weight, easily built elements that quickly convert the SOT to a single aka sailing boat called the Scorpion, OR, to a double aka sailing boat with slightly larger ama volume, called the Doubloon. Of the two configurations, the Doubloon is most like the well-known and highly respected, Hobie Adventure Island.

The Corona and the Back Bay are virtually identical models, save for their respective lengths. For the purposes of this article, I’ll focus on the Back Bay version and all the potential add-on systems I’ve incorporated in the design.

THE BACK BAY SOT KAYAK

Specifications: Length overall – 16′ Beam overall main hull – 28″ Depth of hull max – 12” Weight – 48 lbs. or less Displacement – 335 lbs.

This boat is built in the S&G style of construction in 4mm marine ply with 6 oz. plain weave fiberglass set in epoxy on the inside and outside of the hull for full laminate sandwich strength. The build process uses external cradles as building supports, ensuring that the hull goes together with minimum hassle when handling the rather slender and longish hull panels. The boat is bulkheaded internally at three key points. These bulkheads create not only integrated strength in the design, but they also cleanly separate the hull cavity into four unique volumes for gear storage and watertight flotation.

The Back Bay can be configured with a large, open tankwell set aft of the cockpit, or built with a watertight, aft hatch cover for internal storage in a conventional kayak style.

Specifications: Beam overall – 10′ Weight (est.) – 90 lbs. Sail Area – 56 sq. ft. Displacement – 350 lbs. Draft (board down) – 28″

The Scorpion variant is a Sit-On-Top design for fun sailing, paddling, or Mirage peddling… or all three, as the builder desires. There will be a design for a leeboard mount included in the plans for those who are going to build the boat for sailing. Having the aka gull wing form set well forward permits a full paddle swing arc.  The aka beam connectives to the amas is split into a pair of mounting elements. I did this to make for a stronger, single beam mounting struture. With a single beam design, there is a tendency for the am to want to rotate around the beam, making for a very stressed component that could lead to early failure. By splitting the beam and spreading the mounting points, I have given the structure more resistance to this rotational force, making for a more rigid boat in use. This setup will allow the owner to power sail in light air with both the paddle and the sail providing thrust. With the leeboard swung down for sailing, the owner can do some “power sailing” and utilize the Mirage drive, as well as the sail, in light conditions. The Mirage is capable of boosting boat speed enough that it creates apparent wind over the sail, adding power where there really isn’t enough for sailing alone.

The amas are positioned to optimize capsize resistance when sailing off the wind. The amas do not touch the surface of the water at rest in stable trim and provide only minimal wetted surface drag when underway by paddle or peddle. As soon as the sail is loaded by the breeze, though, the ama on the lee side begins to immerse, firming-up the boat and resisting the heeling moments being generated.

The aft deck can be configured as a watertight hatch with full access to the aft sections of the hull, OR a large, diving tank well with self-draining ports. The cockpit is fitted with self-drain ports under the seat as well as forward, in addition to the daggerboard slot. There is a watertight deck plate just forward of the seat, between the knees of the sailor/paddler to provide secure storage for critical items that may be needed on a routine basis. The foredeck has a watertight hatch cover for bow storage needs.

The rig is a fully battened Dacron sail with two reef points and a multi-section, self-supporting mast which steps into a sealed mast socket in the hull. The mast and boom sections can be aluminum or carbon, as budget permits. The sail choice is open for the customer as long as it can be balanced with the fixed positions for the mast and dagger board. The Cunningham is run to the deck of the gull wing aka to keep the rig on the boat in the event of a capsize.

With 56-sq. ft. of sail on a 90-pound boat, this will be a decently speedy boat without being in over its head all the time in a stiff breeze. I suggest two reef points in the sail to allow for sailing in a wide variety of conditions.

This will be a wet boat at speed, yet there are no worries at all for flooding and sinking, save for a truly nasty trip over a reef that shreds the entire underside of the craft. The bow, cockpit and aft hull volumes are all independent, sealed compartments, as are the ama volumes.

Reentry from a swimming session will be easy with a simple, sling, or rope ladder much like those used by rock climbers, called etriers.

The boat is constructed in a multichine, marine plywood style with epoxy glass laminates inside and out in a stitch and glue style. Stainless T-Nuts are embedded in the hull deck surface from below to provide a secure set of mounting points for the aka wing. The amas are held in place on the aka tips by large bungees and a notched lock system. This system provides for quick setups on the beach.

You just fit the aka to the foredeck, insert four, 1/4″ threaded stainless screws with comfortable, knobbed grips and screw down the aka wing. The amas slip onto the ends of the aka and you lift the pair of 3/8″ bungees up and over two raised hooks on the aka ends to secure the ama in place. Simple, easily maintained and near foolproof in operation.

DOUBLOON SAILING SOT

The Doubloon is the second variation on the central SOT theme of this group of boats. In this design, I am looking to provide a more expansive utility application for the base, Back Bay SOT version. The Doubloon is essentially a solo craft and it carries the same, 56 sq. ft. sail, but the overall potential of the boat is expanded through the use of dual akas and full trampolines on both sides of the Back Bay hull. The rendering of the Doubloon shows a daggerboard inserted down through the Mirage Drive trunk, but in use, I would prefer to have the board mounted outside the Back Bay hull as a leeboard. Plans will be supplied with the leeboard solution.

The akas on the Doubloon are spaced to allow for a full paddle stroke with the boat setup as a trimaran. There are two sections of tubing that span the opening fore and aft between the akas from which the tramp is mounted. The trampolines are designed to roll-up on the outer tube section, much like a window shade and they are deployed by an endless loop of light halyard line. With the tramps fully deployed, the inner tube section lifts up and over a holding pin in the aka and the sailor applies as much tension to the tramp as he feels he needs by hauling-in the endless loop line and cleating it off. If a paddling session is desired, he simply pops the jam cleat and pulls the line to roll-up the tramp on the outer tube section. This procedure applies for both port and starboard tramps.

Like the Scorpion, the Doubloon can be built to utilize a Mirage drive in the center well and the need to roll-up the tramps for paddling is essentially negated, (though it is nice to have the option once in awhile as Mirage drives can be difficult to maneuver in tight places)

The aka beams are held to the deck of the Back Bay hull with the same, threaded knob strategy for quick setup and takedown times. Similarly, the amas are held to the aka ends with hefty bungee cords for the simplicity of use. There’s another, rather invisible, benefit to using the bungee cords for ama mounting. Because they are being held in place through a fairly dynamic hold-down system, the amas can move about, ever so slightly, while underway. This allows the amas to have some structural “give” and the result is that the banging and thrashing that is typically experienced by the ama, is somewhat dissipated through the flex of the joining system.

All in all, I think the Back Bay SOT should be a really fun boat to own for warm water/warm weather boating adventures. It has the capacity to carry enough gear for several days out on the water. When rigged with a sailing system of your choice, it can also cover some pretty good distances if the winds are favorable. Plans for this boat and all its variations will be available from this site and Duckworks Magazine.

Solo 12 and 14.

CORSICA 15R

Sports car performance on the water.

Over the past couple of years, I have taken a break from my boat design work. During that time, I’ve been able to reassess my connection to the craft. The last boat I designed was the Europa 20, which is a trimaran meant for vertical strip foam construction with sandwich style, infused epoxy/glass laminates inside and out. The Europa is a boat for very fast day sailing with a very light hull and a very big rig. A boat that is not for everyone, to be sure, as it requires a level of skill that the average guy does not typically cultivate in the course of experiencing their recreational boating interests.

In stepping away from the larger, more powerful beach type multihulls, I came around to the desire to produce a smaller, very quick and sensitive boat that would appeal to recreational sailors and not just those guys who want to blast around with their hair on fire (though I do suspect that in the right hands, this boat will do just that). The new design had to be easy to build with standard, marine plywood/epoxy/glass techniques that did not rely on exotic layups with spendy carbon cloth. (Well, maybe the carbon will sneak in there a bit on the beams for the guys who want to play with a bigger rig)

Looking long and hard at the smaller skiff-like hull designs I had done before, such as the Montage, I decided to draw the new boat in that same general size, but with a very different approach when it comes to how the boat achieves its performance potential. Where the Montage has a relatively spacious cockpit capable of taking on a couple of adults, (or a parent and a couple of smaller kids) the new, Corsica 15R trimaran would be for one adult (or accomplished kid) designed solely for a unique, one-up sailing experience within the small beach multihull genre.

As a result, the boat has minimized clutter when it comes to excessive high-tech trickery. With that approach, the Corsica 15R is also going to be a boat that has much lower maintenance requirements in order to keep it in top sailing condition, as well as a much lower realized cost to get it on the water and ready to sail.

If you are into cars, as I am, then think in terms of a nicely pumped, Mazda Miata, type of boat that would be a cool, weekend canyon racer for one person. A boat that could blast around the local waters in a good breeze and give chase to other small, fast, multihulls being sailed by crews of two.

The result of this conceptualizing process is the Corsica 15R. The C15R is a boat of modest, marine plywood build techniques and is very light weight for its generous sail area. With this boat, the normal sailing position would be the skipper, semi-reclined within the main hull, driving his machine like an F1 Grand Prix car. In this configuration, the boat is designed to utilize foot pedals for steering, leaving the hands free to work the sheets. But, that’s not the only way to sail this boat. Owners who wish to sail in a more conventional multihull style, can sit-up out of the cockpit and onto the main hull cockpit gunnel, or even the trampoline surfaces all the way out to the ama, where they will steer with a tiller extension.

A construction style in multichine, 4 mm marine plywood, allows the boat to be assembled in a well-understood fashion that will go together quickly. With a subtle placement of minimal stringers and sufficient bulkheads, the C15R becomes a strong main hull shell that can absorb the loads from its sizeable rig, turning the power of the sails into forward thrust in the water.

There is no fully enclosed transom on the vaka hull. The cockpit deck is slanted gently down and aft for automatic self-draining, such as is seen in sport dinghies and larger race boats. A collection of bulkheads under the cockpit deck provide structural support and watertight compartments ensuring that the boat will not likely sink even if large sections of the bottom are torn out from an underwater hazard while smoking along in a gin clear lagoon.

The demounted boat can be assembled easily by one person. The gently gull-winged akas are built with a glassed box beam core.  The inboard ends of the akas slide into tapered sockets in the main hull and are levered in place with stainless waterstays to make ready for sailing. This, tapered socket technique prevents binding while assembling the boat, while providing a solid, hassle-free and weight minimized demounting system. The leading edges of the akas are smoothly shaped foam blocks that are glassed onto the box beam to provide an aero component, as well as creating reduced drag from waves and spray. The akas are hard fastened to the amas as a complete assembly that is easily removable from the vaka hull. The trampolines stay mounted to the akas and amas for transport and only have to be hooked and tensioned to the main hull during assembly.

The mast is a stick from a Hobie 16. I specify the addition of a set of spreaders from the Hobie 18 mast to stiffen up the H16 mast to handle the additional righting moment generated by the Corsica design. Naturally, I’d prefer to see fresh sails in something like fully battened, Pentex laminate, but builders on a tight budget could also work with a loft service to tweak a reasonably fresh Hobie 16 main and jib and do just fine. The addition of reefing points on the main are strongly suggested, as well as the use of furlers for the jib and spinnaker/screacher. For those who desire fresh sails for this boat, I would recommend the folks at Whirlwind sails in San Diego, California. http://www.whirlwindsails.com/

A removable carbon prodder sets the tone at the front end of the boat. The stick originates as a carbon windsurf mast, so it is easily found on the used market and equally replaceable, should it get poked into an unyielding environment. For trailering, the sprit unpins, slides out of its socket and is stowed in the cockpit for transport and storage.

Corsica 15R Specifcations

LOA                                         14’ 11”  (4.54 m)

BOA                                         13’  (3.96 m)

Displacement                         650 lbs.  (294.8 kg.)

Sail Area (upwind)                 218 sq. ft.  (16.17 sq. m)

Spin                                       142 sq. ft.  (13.19 sq. m)

Mast Length                           26’  (7.62 m)

Draft (board up)                     1’  (.3 m)

Draft (board down)                42” (1.07 m)

The mast is raised by the traditional beach cat method of physically lifting the mast with the base pinned to the mast step, or by utilizing the long daggerboard in its trunk as a form of a gin pole. A forward hoisting line is led over a pair of sheaves at the top of the daggerboard and down to the hand cranked winch on the trailer. Mechanical leverage quickly raises the mast so that the forestay can be fastened to the bow, stepping the mast securely. You can see a few photos of the process at Brent’s L7 trimaran site:

http://home.comcast.net/~ritakend/site/?/page/Mast_Raising/&PHPSESSID=864f3404e3f46ed29dd99b863018fc1d   This is a very simple way to raise a mast should you need to avoid the trad lifting exercise for one reason or another.

I chose to not go with tricked-out, curved lifting foils in the amas due to construction complexity and added cost for the builder. Foils of this type are hard to build correctly by hand, as are the needed curved trunks in which they slide. Instead, the boat is equipped with a daggerboard that is inserted through the deck of the main hull in front of the mast which angles aft to exit the hull below the waterline. A daggerboard and trunk of this type are much simpler forms to build and orient in the hull. It is also just one main foil, where lifting foils need to be made in pairs, one for each ama. Lifting foils also need complex control mechanisms to retract and deploy the foils and they have to work from the cockpit remotely with the foils mounted way out in the amas. The needed controls are an interesting problem when the boat is 13’ in width and the driver is semi-reclined in the main hull.

Note: I’m not against an owner who might want to experiment with foiling for this boat, even if it is just foil assist and not full flying. It would require a lifting t-foil style rudder and twin Bruce style foils in the amas, or, if a person is really accomplished as a composites builder, they could make a pair of matching c-foils for the ama. The owner just needs to know what level of additional work is involved and at what skill level they need to perform in order to get the desired result.

If you are on a budget, the rudder and headstock from a Hobie 16 will work just fine for the Corsica with some mods to the tiller. The more deluxe, Rudder 25 system from Dotan will also work well, should you have the coin.  http://www.dotan.com/  If you plan on pushing the boat hard, then a longer blade will be required, or you can get yourself invested in the process of putting a rudder on each ama and have stunning control at your finger tips. On the down side, that change will cost you a bit out of your pocket and at the launch ramp in setup time… though I can see a nifty rig with light alu tubing and the use of snap buttons as a cool solution.

The Corsica 15R will be a light boat built from familiar materials. It should be a fairly simple building experience for the owner and will fit comfortably into any typical garage space, making it easy to find a building location. It will quickly assemble for sailing and be hassle free with minimal maintenance required to keep it in top form. It can be towed behind any compact car on a typical beach cat trailer and when demounted for travel, is road legal anywhere in the world. On the water, this boat should be quite quick and behave with predictable, pin-point sailing manners. With the skipper slung comfortably in his reclined cockpit seat, he will be decently protected from the effects of the weather and sea state while tearing around his local waters.

NAGARE 21′ AND 17′ MIRAGE DRIVE SPEEDSTERS

Making use of mirage drive propulsion with more efficient hulls designs.

Nagare  (nah-ga-ray) is a Japanese word meaning Flow.

Both of them are configured as trimarans with fairly small and unobtrusive amas designed to give the boats remarkable stability in a wide range of conditions while allowing the vaka, (main) hull to be decidely slender for more effective drive through the water.

The Nagare sisters also have incredibly narrow waterline beam numbers that, when coupled with their fairly long hulls provide for very easily driven hull forms for high efficiency per unit of energy applied.

I expect both boats to operate at the very high end of commercially available paddled boats of the same length, beam and weight. So, yes, they can go pretty quickly, but that’s not the real purpose.

The real benefit of the design genre is through the ease with which they are propelled at any given speed, compared to other boats of their size. This efficiency translates directly to those using the boats as less tiring for miles covered, or greater speed with the same effort as other, wider designs.

Because the propulsion is derived from the largest muscles in your body, the leg muscles, rather than the arms and shoulders, there will be less fatigue for each mile traveled. Because leg muscles are so much bigger than arms, they will be able to do more work in a given period of time, making for longer possible trips, as well as the mentioned lower fatigue issue. With a less fatiguing effort, more people will be able to enjoy the experience of being out on the water for daylong adventures.

NAGARE 21 DOUBLE SPEED AND STABILITY FOR DOUBLE RECREATIONAL BOATERS

The Nagare 21 uses a set of amas, mounted on a pair of simple, anodized aluminum tubes with quick release snap buttons holding the sections together for easy disassembly for car-topping. If a trailer is used to transport the boat, the beam of the Nagare 21 falls well below trailer maximums, so nothing special needs to be done to take the boat to and from the water. Two Nagare 21’s can be trailered, or car-topped, by removing one of the amas and placing the main hulls close to one another on the racks, or trailer. The removed amas easily fit inside the hulls and they are ready to go. The whole affair on the rooftop is very much like a pair of sea kayak doubles. Because of the length, I would not mount a boat this big on any compact cars. You would be very likely to rip the rack right off the roof in strong side winds.

Steering is by means of a simple, flip-up style kayak rudder with control lines run through the hull to a convenient steering lever in the cockpit. I suggest the SeaLine SmartTrak rudder system (do a search for supplier), the P-41 Multi-purpose rudder from Onno Paddles http://www.onnopaddles.com/onnocomponents.html and the Feathercraft rudder system for hardshell boats. http://www.feathercraft.com/accessories/rudders-hardshell.php   These are really great rudder units and will give excellent steering control with minimum drag.

NAGARE 21 SOT OPTION

This boat can be built with a full cockpit tub so that it functions as a Sit-On-Top kayak with full drainage through the Mirage drive openings. Auxiliary drain ports are located in the tub for rapid removal of any water that comes in over the side of the hull. I suggest the SOT option for warm water users, with the more traditional kayak style, Sit-Inside hull form for those who will be using the boat in colder water, or more frequent inclement weather.

The SOT version has internal bulkheads for support of the SOT tub, along with the capability of adding a small circular deck plate for an additional watertight compartment in the cockpit that is perfect for small items, such as cameras, wallets, car keys, etc.

The SOT variation is an optional element to the base plans. If you wish to built it as an SOT, drop me an email at my regular email address and I’ll get back to you.

ROUGH WATER USE

This is not really a boat that is meant to go out in rougher conditions, such as those where a full-blown sea kayak might be right at home. It’s meant for quieter waters, such as lakes, bays, harbors and bigger rivers. It can take a session in 1 or 2 foot breaking surf, but I would not expose the boat to bigger waves, especially in a shore break scenario. You may find yourself out from the shore a bit when the wind comes up, producing steep, choppy waves. The basic Nagare 21 will handle this easily because only the cockpit will be exposed to swamping. The amas will keep the boat stable while you pedal to shore, or a quieter place on the water, where you can bail-out the boat and continue.

It is a perfect boat for sightseeing, bird watching, fishing, photography, and just simple, energy efficient cruising with near bomb-proof stability (you can stand up in the boat while out on the water without your partner coming completely unglued, for instance).

The Nagare 21 is a fast, comfortable and unique boat for a couple who like to get out on the water, but do not want to hassle with the business of capsize that is present in other types of boats, such as kayaks and even canoes.

NAGARE 17 SINGLE A NEW STYLE OF SOLO BOAT FOR TROLLING FISHERMEN

The solo version of the Nagare series has some very different twists, compared to its bigger sister. It has the same, highly efficient and easily driven, slender hull technology, the same set of trimaran style amas well aft for big time stability, the same generous cockpit opening and the same convenient utility for car-topping or lightweight trailering.

The design elements that set this particular boat apart from its sister craft is that the Nagare 17 has a very special capability when it comes to fishing.

AFT FACING TROLLING

Anybody who builds the Nagare 17 and intends to use it for fishing will probably be knocked-out by the potential for facing aft while trolling. Imagine using your legs to quietly drive the boat forward while you casually set trolling rigs, eat a sandwich and keep an eye on the fish finder… all while keeping an eye on the rigs you have set, with them easily at hand?

This is the signature utility development with the Nagare 17, designed specifically, for fishermen. It works like this…

The fisherman loads his boat, drops into the forward facing seat, hits the iPod for his favorite tunes and jams out across the lake at a remarkable speed for a human powered boat. He zips across the lake in virtual silence because he’s driving a very skinny and efficient hull with no engine sounds. Once he arrives, he’s going to make a few sneaky trolling passes with his Mirage drive pushing him along over that monster crew of Pike that are hanging around on their favorite piece of structure. Wham! Fish On! and the day starts with smile on his face.

If you’ve ever fished from a typical Sit-On-Top, you know that you have to face forward while trying to look over your shoulder while trolling. Hook-up and then you have to swivel around, grab the rod and go after the fish. All the time you are doing this, you have to balance the boat carefully, because the whole tamale could go over and end your day right then and there.

Well, that’s how you used to do it, anyway.

With the Nagare 17, you can take it to a whole new level of fishing pleasure. The Nagare 17 is equipped with twin Mirage drive trunks. When driving the boat forward and facing forward, the Mirage drive is dropped into the forward trunk and a tractor-style seat is dropped into the aft trunk with the seat bottom resting on the top of the trunk.

To convert the boat to aft facing trolling and fishing, you simply stand up in the boat and swap the Mirage drive for the aft mounted seat plug and the seat then goes to the front trunk… facing aft. With the Mirage drive still set to drive the boat forward, you simply sit down and start pedaling, slowly, up to your desired trolling speed.

Now, you can watch your fish finder, GPS and your trolling rigs while you continue to tool along at your favorite speed for nabbing the fish. Get one on and simply work that rod while continuing to face aft. No twisting around in your seat, no ”just about dumped it” scenarios, just simple, fun fishing in a very stable boat. What could be cooler than that?

With the fore/aft balance point of the boat set right between the two drive trunks, there is but a very minimal change to boat pitch when you change the direction you face.

The Nagare 17 is further designed to accept an insulated and watertight tank between the two aka tubes where they run through the aft deck. You can use this for all kinds of stuff like: your catch, fresh bait storage, cold beverages if you catch and release… whatever suits your needs. There is plenty of room between the two drive trunks for a pretty good sized tackle box and lots of room up forward of the trunks for any of that “other stuff” that fishermen seem to sneak aboard their boats.

A moveable electronics unit can be fastened at the forward end of the cockpit, or unhooked and moved around aft if you’d rather have it facing that way.

Maybe you want to cast lures or flies instead of troll. The boat is so stable with the two, wide set amas, that you can stand up and cast all day without ever feeling like you are getting the least bit tippy. All in all, the Nagare 17 is quite a boat for fishing, as well as just plain fun, recreational pursuits.

The Nagare sisters represent a unique design family for human powered vessels. They are quick, stable and with their unique styling, represent a distinct departure from the looks of traditional boats one typically sees on any given shore or launch ramp. Both boats are designed to be built in marine ply Stitch and Glue methods for the hull sections, with cedar stripped decks to take advantage of the really beautiful, smooth curves capable from that style of building. You can paint the lower sections of the hull and leave the cedar decks natural with a deep varnished finshed, for a real knock-out boat that will really gather a crowd.If you really want to have a plywood deck build instead of the cedar strip build, write and twist my arm gently. I can design that change for those who really like to build that way

Plans are not yet complete, so if you would like to build one of these two boats, please send me an email and I’ll put your name on the mailing list for information, or watch the plans section of Duckworks for the notice.

Another Trimaran/Skiff … Bigger, With More Power

Well, you had to know this would happen…

When the Montage Skiff/Trimaran was introduced, the Lunada Design website was absolutely flooded with an ocean of page hits every day right after the article was posted. I received several dozen personal query letters regarding the boat and sizeable slice of them were directed at the potential of a bigger version of the Montage.

The concept of being able to build your own boat and rig it with a used mast and possibly even used sails, (if they are in good enough condition) had struck a chord with the homebuilding community. The creation of a larger version of the Montage would take the specified rig choices up into the much more commonly found beach cat rig sizes and make the business of finding a used rig in great shape, a whole lot easier. After pencilling a collection of thoughts and running some rough numbers on the potential, the idea came into focus as the 18′ Collage.

The ama shapes, especially on the smooth hulled variation, borrow other design cues from the modern performance dedicated French designs of VPLP, as well as the very cool work of Nigel Irens. The transoms are nudged in the direction of a triangular shape, while retaining some of the typical beach cat, flat-topped U-form feeling. The volume concentration is well-forward, with the foredecks being much more rounded to provide rapid shedding of water. These shapes will help to reduce the tendency of multihulls to pitchpole when sailed hard.

Breaking away to some degree, from the single, build style of the Montage offering, the Collage is presented as a fully strip built, smooth hulled version, as well as a multichine plywood version. These choices will give builders the ability to work with the material choices and aesthetics they prefer. I am also looking at the potential for a foam cored sandwich laminate boat using the vertical strip technique, though that iteration will probably come around a little later in the process.

Collage Specs

LOA 18′  ( 5.48 m ) BOA 14′  ( 4.26 m ) BOA main hull 41″ ( 1.04 m )

Sail Area Main 163 sq. ft. (15.14 sq, m.) Jib 55 sq. ft. ( 5.12 sq. m. ) Spinnaker 161.5 sq. ft. ( 15 sq. m. )

Displacement 1000 lbs. ( 454.5 kg. ) Weight 380 lbs. ( 172.7 kg. )

The Collage meets all the same design criteria as does the Montage, except it’s longer and wider, has more sail area, carries more crew weight and yes, it’s going to be faster in the right hands. Faster… sometimes this term can be kinda self-defeating when speed claims are made compared to another boat. When it comes to recreational boats, I’m of the opinion that speed is a relative thing based on the overall design brief of the boat in question. In the case of the Montage and Collage designs, speed is one of the attractive elements as long as it is kept in perspective with  just what the use application will be from day to day. From where I sit, this will be primarily recreational purposes.

The Sail Area to Displacement ratio ( SA/D ) for each of the boats is as follows: The Montage is 31.56 and the Collage is 34.88 With both of these boats being sailed at near max displacement, I give the nod to the Collage, based on waterline length, as well as the ability to punch through wave conditions that will toss the Montage around to some degree.

I would like to see this pair of boats ( Montage and Collage ) blasting around in the hands of skilled sailors. There’s nothing quite like the feel of a performance boat and the way it can deliver the exhilaration of a spirited ride. But… I’d also like to see this boat out on the water being used by families while they have a really fun day on the water with, maybe, a somewhat toned-down speed blast tossed into the mix every now and then to get the kids chirping.

I’m looking at the potential for the Collage to create a new beach and/or lake sailing culture in which energetic hot shoe dudes, as well as young sporting families, can all mingle on the beach, out on the water and share a communal BBQ after the day of sailing. I grew to maturity on the beaches of SoCal watching the brand new Hobie Fleets do this very thing and it was a lifestyle that perfectly fit my beach kid way of thinking. It would be great to see that happen once again. Could this take place in 2009? Hey, I don’t know the answer to that one, but it is fun to think of the boat and its owners in those terms.

There’s a lot going for the Montage/Collage design approach to support such a social event concept. Both boats are affordable to build, they are easily trailered by even sub-compact cars, they make use of “experienced” parts that can be had on the open market for pennies on the dollar when compared to new parts and they are boats that are easily sailed on the first day. This last part is important, as the boat will attract more enthusiasts when they see that they can be sailed with what pretty much passes for beginner’s skills. Just because it can go fast, does not mean it has to be sailed that way. As the owner’s skills grow, the boat’s potential will be there waiting for him.

As a way of introducing the Montage and the Collage designs to the homebuilder market, I’d like to offer free plans to one person. This builder should be able to show me that they have a very strong interest in either design and are willing to build the boat as I supply the plans in accordance with their progress from the previous plan set delivery.

If interested in this offer, you can write me at: Chris@Wedgesail.com or at lunadadesign@gmail.com and make your pitch. The one chosen to receive the free plans will be willing to provide construction photos of their progress and a brief written description as to how things are going. The personal accounts will be published on this website, Lunadadesign.net so that the readers of the site can follow the projects.

Chris Ostlind Lunada Design

This boat created immediate appeal to beginning and intermediate sailors. It offers much of the speed experience of a high performance skiff in a stable and predictable platform that is really tough to capsize. The Weta is one of the first boats to encourage family participation and reintroduces the waterborne fun of the beach sailing culture, established way back in the late 60’s with the intro of the Hobie catamaran.

A brand new, factory built Weta goes out the door for USD $11K. Realistically speaking, this isn’t an in surmountable amount of money for a factory produced, brand new carbon trimaran. It is, however, quite a lot of money for most casual recreational enthusiasts and the folks who like to build their own boats… especially when you consider the rugged economic conditions we all face these days.

The estimated $5600 figure represents a boat with a whole host of brand new parts. For the clever builders out there, the Montage could be even less expensive if they can find a used 470 rig, perhaps a used small craft, or beach cat trailer that could be modified to fit the hull design and even a collection of hardware in good condition. The Montage is a very light boat at right around 235 lbs., so you do not need to buy a heavy duty trailer.

I went back to the drawing table and reconfigured everything so that the longest hull panel was going to just fit on a couple of sheets of marine ply laid end to end. The main hull also got just a bit wider in the process of lengthening the boat. Where the factory boat uses carbon fiber on foam cores for its structure, the Montage will be a 4mm marine plywood design with full fiberglass/epoxy sandwich laminates inside and out. The foredeck and the cockpit seating transitions are strip-built in Red Cedar to give the overall appearance of the boat a smoother, more organic feel than straight plywood panels.

The amas for Montage came from a 16′ trimaran design that I had already done and required minimal re-design to work with this boat. The amas are also designed as multichine ply forms with pretty high volume shapes well forward and a water shedding deck form that will helps to keep them riding high even when driven hard. Ama displacement is 100% of the all-up boat weight when sailing.

Montage Specifications

LOA                                   15′ 6″ BOA                                   12′ BOA main hull                  41″

Main                               110 sq. ft. Jib                                      38 sq. ft. Screacher                      102 sq. ft.

Displacement                 650 lbs. Weight                             235 lbs.

The aka beams are anodized aluminum instead of carbon tubing. The inboard ends fit into fairly burly sockets in the hull and are held in place with quick release pins. Flat deck flanges on the ama ends are welded in place and bolted to the amas. The amas are removable from the aka tubes for repair or maintenance, but otherwise stay mounted, along with the trampolines, as complete units.

The mast is also anodized aluminum. The boat uses the same mast section as the 470 dinghy, which is a Proctor Cumulus section. This mast is available on the used market with a little bit of hunting around. If you want it all and have the money, then there’s a very cool, filament wound Forte carbon spar available with very close specs to the Proctor that will rock your world. http://fortecarbon.com/

Making these two changes from the benchmark, all-carbon Weta to an aluminum spar and tubing keep the costs down, with but a slight weight penalty over all-carbon parts. If you find a used mast, the savings will be even more substantial.

I have found that the more expensive sailcloth laminates are capable of driving the boat just a bit faster, but for the average recreational sailor, they will hardly ever make a difference compared to more forgiving sails in Dacron. Dacron is much easier to maintain, lasts longer, is a lot more tolerant of UV exposure and can be repaired by any sail loft wherever you go. If the builder of the Montage really wanted to, they could buy a set of sails in something like Pentex laminate instead and they’d have that hot, performance boat look that some desire along with just a bit more zip under sail.

The aluminum aka tubes will be sold pre-bent and ready to install on the amas. If the builder has access to a good mandrel bending facility that can handle the OD/ID specifications of the tubing, they can fabricate their own tubes to supplied specs.

The Montage is designed to be a really fun day sailing machine that can generate near performance skiff sailing speeds while offering a hugely stable platform for recreational sailing. Construction of the boat is very straightforward in marine plywood with glass/epoxy laminates and can be easily built by any sailing enthusiast who has household handyman skills with tools. The Montage has been created to offer homebuilders an opportunity to enjoy this style of family sport boat at a completed cost that is far less expensive than the manufactured version.

Fresh take on the solo16 s, a safe, speedy solo cruising craft for adventurous souls.

After a lot of input from readers of this site, I have completed the modifications to the Solo16 S design that reflect many of their expressed interests.

The Solo16 S now has a bit more displacement as a direct response to suggestions for the use of a small 2 hp outboard and some spare fuel. At the same time, the vaka hull was given additional beam above the waterline and the shear was raised some to allow for mods to the amas.

The amas, themselves, were made slimmer and taller, while retaining the same volume. They now have a slight vee section which gives the boat a progressive resistance increase as the amas are pressed heavily in a gust.

To complete the changes, a sporty all-weather soft cabin has been designed to allow the owner a chance to sail in a wide spectrum of conditions. The new cabin is modular in its approach with the ability to address a multitude of sailing situations.

All panels except the Bimini have generous window areas which are backed by micro mesh screen that is small enough to keep out the No-See-Ums. The PVC windows are zip-out removable and the screens can be rolled-up for maximum airflow through the cockpit. The complete enclosure system allows the owner to mix and match the panels as needed for the best protection from the elements.

When setting up the boat for sailing while on the trailer, the owner simply lifts the ama assembly, rotates and places the ends of the aka tubes into the matching vaka openings and slides the ama into place. The akas are fully seated when their internal, spring loaded snap-buttons click into place. The entire ama assembly is easily handled by one adult with modest physical strength.

In the trailering mode, the complete boat does not exceed 68″ (1.7 m) in width, falling well under every trailer width limit in the world.

16 Best Trimarans For Sailing Around The World (And a Few For Daysailing)

As an Amazon Associate, we earn from qualifying purchases. We may also earn commissions if you purchase products from other retailers after clicking on a link from our site.

Trimarans are growing in popularity worldwide, due to their light construction and high stability these multihulls are even faster than catamarans. Trimarans are still one of the lesser-known boat types so in this article ill be checking out some of the most popular models.

The best trimarans include: 

• The Neel 43 
• The Neel 47 
• Dragonfly 28 
• The Pulse 600 
• Corsair 37 

These tris are built with your safety in mind while also packing powerful speed and a wide array of comfort features to optimize your sailing experience , some are even foldable making them possible to load on a trailer and transport to the sailing destination of your choosing.

In this article, I have created a list of the 16 best trimarans in the market and their unique features. You’ll also learn the best options for different purposes such as circumnavigation, weekend sailing, racing, and more. 

Table of Contents

What Is a Trimaran?

A trimaran is a multi hulled sailboat with three individual hulls; the main hull ( vaka ) and a pair of outrigger hulls ( amas ). These smaller outrigger hulls are attached to the main hull using beams. 

While trimarans have a rich history dating back nearly four millennia, these types of sailboats have only gained popularity in the late 1900s and early 2000s. 

Trimarans are primarily used as personal boats for sailing enthusiasts or racing. These sailboats draw their versatility from their lightweight design, making them faster and easier to handle at sea when compared to single-hulled boats (monohulls). Additionally, the three hulls also contribute to better stability, making it very hard to capsize (although more likely than a cat according to this study)

Trimarans come in various sizes, and some can be as small as 19 feet (5.8 meters) in length, while others go up to 60 feet (18meters). They’re also used for different purposes. Most trimarans are used for racing and recreational purposes, although some units are still used as ferries.

As with all things, to find out which is the best we need to understand what it will be used for. There is a big difference in requirements between a boat used for day sailing compared to offshore around the world sailing.

The list below highlights the best trimarans for different purposes.

Best Trimarans For Cruising, Liveaboard and Sailing Around The World

The Neel 43 is a French trimaran best suited for cruising. Its key features include: 

• Easy maneuverability on the open sea by only a small number of crew members 

This unit is also built for comfort, ideal for more extended travels. This 43-feet (13-meter) trimaran is also made with recyclable and bio-sourced materials, highlighting the manufacturer’s commitment to environmental consciousness. 

This trimaran has a base price of  €329,000 excluding VAT. This translates to approximately $370,138. 

2.Neel 47 Possibly The Best

Named the best full-size multihull for 2020, the Neel 47 is a strong contender for one of the best trimarans in the market. This 47-foot (14.3-meter) long trimaran features optimized exterior and interior ergonomics for a unique design and look. 

Still on design, the Neel 47 is ideal for couples looking to take a weekend off or spend some time as liveaboard. It has a spacious owner’s cabin and two bedrooms. It also features a spacious living room and kitchen and is optimized to ensure comfort for a couple. 

The Neel 47 also has two basic guest cabins so your friends or children can tag along on your sailing adventure. Accordingly, this unit is ideal for those looking to explore the sea for the sheer joy of sailing. 

The Neel 47 comes at a 571,139 euro ( $643,600 ) price tag, excluding VAT. 

3. Rapido 60 The Fast and Comfortable Circumnavigator

The Rapido 60 offers a blend of performance, safety, and luxury, making it one of the best options for bluewater sailing. Measuring 59.3 feet (18 meters) in length, the Rapido 60 is an imposing unit. It’s made from lightweight sandwiches and carbon materials that provide speed and strength, allowing it to stand up to strong ocean currents. 

The Rapido 60 also has spacious living spaces and is built for comfort at all points of the sail. Its design also optimizes safety. While it’s an ideal option for circumnavigating, it’s also an excellent choice for racing due to its speed. 

This is also the same boat that The Youtube channel La Vagabond just purchased.

The Rapido 60 retails at $1,400,000 . 

4. Rapido 40

The Rapido 40 measures 39.4 feet (12 meters) in length and is ideal for cruising around the world. The Rapido 40 features twin “C” foils, which provide added lift, enhancing its speed and performance whether you are sailing downwind or upwind. 

Because it has C foils, this trimaran doesn’t have a central daggerboard, increasing interior space. Accordingly, it’s an excellent option for couples looking to cruise and enjoy great performances .

The Rapido 40 is made from high-tech all-carbon materials for a lightweight yet sturdy design. This material is also used for the countertops and furniture, and the cork flooring adds a touch of style.

This trimaran retails for $595,000 , making it a cheaper option than the Rapido 60. 

5. Dragonfly 40

The Dragonfly 40 measures 40 feet (12 meters) in length. It features high-comfort standards, making it one of the best trimarans in the market for taking your family for a cruise. Because of its larger size, it has a better capacity, being capable of accommodating six to eight people, so you can bring your family and friends along. 

It’s easy to navigate and extremely safe. With a maximum speed of 24 knots (44.5 km/h), this trimaran also provides fast speeds to make your cruise even more exhilarating. 

The Dragonfly 40 retails from €509,000 exclusive of VAT, which rounds up to $572,000 . 

6. Dragonfly 32

The Dragonfly 32 is a high-performance cruiser. Like the Dragonfly 28, this unit features a contemporary design for racing. This trimaran can accommodate five to seven crew members. 

Although slightly longer than the Dragonfly 28 with its 32-foot (9.8-meter) length, the Dragonfly 32 has a max speed of 23+ knots (42.6+ km/h), making it one of the fastest trimarans for racing. This unit also has comfortable accommodation, which makes it an ideal option for a weekend cruise with family and friends. 

The Dragonfly 32 has a base price of $350,000 . 

7. Corsair 37

Thanks to a variable draft with a retractable rudder, the Corsair 37 is an ideal choice for shallow water exploration. This 37-foot (11.3-meter) long trimaran features advanced foam-cored construction designed for safety, making it virtually unsinkable. 

The carbon hulls minimize weight, this makes for a lightweight ocean exploration sailboat with blistering speeds. One of its selling points is that this trimaran has previously been used for Arctic expeditions, possibly marking it as one of the better options for circumnavigation and offshore sailing in the northern waters. 

This trimaran has a base price of $189,000 but can go up to $204,125 .

Best Trimarans For Day/Weekend Sailing

8. dragonfly 28.

The Dragonfly 28 is a 28-feet (8.75-meter) long sailboat that can accommodate up to five people. It comes in two versions: 

• Touring version: This version is ideal for families.  
• Performance version: This is built to provide optimal performance for the sports enthusiast within you. 

It clocks a maximum speed of 22+ knots (22+ km/h) and is beam-folded. It’s an excellent option if you want a high-performance, comfortable yet smaller unit for your day or weekend cruise. 

The Dragonfly 28 starts at  €188,280 inclusive of VAT, which comes to around $211,600. 

9. Dragonfly 25

Like other trimarans under the Dragonfly brand, this 25-foot (7.62-meter) trimaran is great for both racing and short term cruising. However, this high-performance boat delivers easy handling, making it perfect for couples looking to take a ride out over the weekend and seasoned sailors looking for an exhilarating racing adventure. 

The Touring version features a lightweight build and offers comfort and accommodation to keep you, and the few guests you can fit, comfortable during the ride. This trimaran also has a Sport version, which is optimized for racing. 

The Dragonfly 25 retails from EUR 86,800 . 

10. Pulse 600

The Pulse 600 trimaran is a compact sailboat. It’s made from lightweight, carbon-reinforced construction and vacuum-formed materials for optimal speed. This trimaran is an ideal option if you are looking for speed. 

It also features ample deck space, greater stability, and volume than most trimarans of similar size and build. 

This trimaran measures 19.8 feet (6 meters) in length and can be sailed single-handedly by one person with minimal effort. The Pulse 600 has a base price of $38,800 , which places it in the lower price range. 

The F-22 is one of the smaller trimarans in the market. Developed in New Zealand, the F-22 is a folding trimaran built for speed. The hulls are made from narrow fiberglass tied together using fiberglass beams and aluminum, minimizing bulk while optimizing speed. 

The F-22 is roomy and is not as pricey as other models in the market. This trimaran has two main versions: 

12. 2019 Weta Trimaran

The 2019 Weta trimaran is a 14.5-foot (4.4-meter) trimaran featuring a carbon frame, centerboard, rudder foil, and rudder shock. The hull is made from fiberglass and foam. The Weta is built for strength and speed based on these lightweight materials. 

The 2019 Weta trimaran is easy to sail and is worth considering whether you want to take a quiet sail, race with your friends, or take kids to a sailing lesson. It has a simple design and is easy to set up independently. Thanks to its collapsible design, this trimaran is easily stored away with minimal space demands. 

13. WindRider 17

The 17.4-foot (5.3-meter) WindRider 17 is one of the more versatile trimarans in the market. It packs high performance for a low cost. This trimaran has a light rotating mast to boost performance, and a full-battened mainsail optimizes visibility. 

This sailboat is made from rotomolded polyethylene, which is more durable than fiberglass and demands less maintenance.

The WindRider 17 has a comfortable interior and can fit six adults. This is an ideal choice for social sailing for a couple or a family and friends. It’s easy to ride, and a shallow draft allows easy maneuverability. 

14. Astus 22.5

If you’re looking for something small but still comfortable, this 22.5-foot trimaran is for you. Built for speed and maneuverability, the Astus 22.5 has optional foils to optimize speed. The modern design, coupled with the spacious interior, can fit up to four beds. Accordingly, this trimaran is suited for family outings. 

This trimaran also has a foldable design, collapsing to only 16 feet (4.9 meters) for easy storage. 

15. Multi 23 Trimaran 

The Multi 23 trimaran has a contemporary design, featuring a vinyl ester and PVC foam core construction. The section below the waterline is made of solid glass for a sturdy base.

The beams are made of lightweight carbon, and the trimaran features a 33-foot (10-meter) aluminum rotating wing mast for optimal harnessing of the wind. While ideal for weekend excursions with family, once rigged with the asymmetrical spinnaker will get your heart pumping.

This trimaran packs high performance at a lower cost than most other options in the market. It’s a good choice if you are looking for a high-performing unit without spending an arm and a leg. 

16. Challenger Class Trimaran

The Challenger Trimaran 15 is the best choice for persons with disabilities. It’s designed to provide disabled sailors an opportunity to explore their passion for sailing without worrying about aspects like safety or operation. 

A man named Geoff Hold circumnavigated the British Isles in 2007, becoming the first disabled person to achieve this feat. He had quadriplegia. 

Living up to its name, the Challenger can withstand harsh weather conditions while blending performance with speed. 

Final Thoughts 

Admittedly, no trimaran is best for everyone. But whether you are looking to race with your friends, take your loved ones or friends for a cruise over the weekend, or circumnavigate the ocean, you can rest assured that these lightweight trimarans will deliver speed, safety, and comfort to make it worth your while. 

These brands are innovatively designed and feature intricate safety mechanisms that make them virtually unsinkable. Give them a shot and begin your ocean adventure.

There have been so many requests for a 2-seater version of the Slingshot 16 Trimaran that I decided to build one for myself and take really good notes. The (very satisfying) result is the "Tandem" version of the Slingshot 16.

The Tandem Slingshot 16 looks and sails a lot like the single-seater version, but shares not a single panel. It has a much longer cockpit (7-1/2 feet) and a bit more beam and rocker, so it accommodates up to 400 lbs of passengers and still is quick and nimble.

And as a special and unique feature of the Slingshot 16 Tandem tri, you also get full constriction plans and photos for my new tilt-up mast step. Now you can just stand in front of the boat, insert the mast into the step at a convenient 45-degree aggle, stant ip up vertical, and lock it in place. Much easier on the back!

So if you're looking for a quick little 2-seater boat that's comfortable, nimble, ultra-stable, super-fast to rig, gets you sailing in just 10 minutes, and will run circles around most other sailboats - you have just found it! The "Slingshot 16" trimaran will hit 14 mph, points higher than 45 degrees, and turns on a dime - all while you (and one companion, if you wish) sit comfortably in your seat, facing forward, with both hands free thanks to foot-pedal steering. She can be launched in 5" of water and sailed away - upwind - in just 7".

Thanks to a special moveable main seat, you can sit in the middle of the cockpit to balance the boat when sailing solo. Or, you can move your seat to the forward position and have lots of room for someone else to sit very comfortably behind you.

Many of the Slingshot 16's benefits over "simpler" hull designs are the result of its hydrodynamically superior 5-panel hull with a flat-bottom center panel, which planes much more easily than ordinary 3- or 4-panel hulls.

And if you'd like to see just how nimble and quick this little trimaran really is, here's a short video of the Slingshot 16 going 10-13 mph, and another short video demonstrating the joys of hands-free tacking - changing direction a full 180 degrees without touching anything but the steering foot pedals.

NOTE: The videos show the single-seater version, but the Slingshot 16 Tandem sails virtually identically.

Although I have 4 trimarans ready to sail (two 16-footers, a 19-footer, and a 24-footer), it's the Slingshot 16 that I always seem to grab when the urge to sail hits me. Although all these little tris are quick, nimble, dry, stable, and a blast to sail, Slingshot 16 just seems to put it all together in the most irresistible way.

Plywood List:

NOTE : My Slingshot 16 is built from 3mm lauan "doorskin" ply costing about $12 a sheet, and from 6mm ply costing about $22 a sheet. Or, you can spend the extra $ for okoume or some other pricey species of plywood. As long as the glue is waterproof , you can use any ply you wish.

Main Hull 2 sheets of 3mm ply, one sheet of 6mm ply (decks).

Amas (outriggers): 2 sheets of 3mm ply, one sheet of 6mm ply (tops).

Plans Include:

• An extremely detailed construction manual including more than 280 photos detailing the complete building process, with over 70,000 words of explanatory text by Frank Smoot.
• A separate drawings manual with dozens of superbly detailed, multicolor CAD drawings by Jerome Delaunay showing every construction detail with crystal clarity.
