Review of J/36
Basic specs..
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.
The J/36 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.
The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.
The boat can only enter major marinas as the draft is about 2.01 - 2.11 meter (6.59 - 6.89 ft) dependent on the load. See immersion rate below.
The boat is typically equipped with an inboard Yanmar diesel engine
Sailing characteristics
This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.4 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.
The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for J/36 is about 224 kg/cm, alternatively 1256 lbs/inch. Meaning: if you load 224 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1256 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 39m 2 (419 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

A boat with a BN of 1.6 or greater is a boat that will be reefed often in offshore cruising. Derek Harvey, "Multihulls for Cruising and Racing", International Marine, Camden, Maine, 1991, states that a BN of 1 is generally accepted as the dividing line between so-called slow and fast multihulls.

The story begins in 1975. Rod, then an ad salesman for the sailing trade magazine, Soundings, and an active one-design sailor decided to build a sailboat he had been designing since completing a Westlawn School of Yacht Design correspondence course in the 60's. With $400-worth of fiberglass and wood, some rigging and hardware left over from a Soling of Bob's, he built the 24′ x 9′ wide ...

outer sunset. May 5, 2006. #9. sam_crocker said: J/36 was the predecessor of the 35. The 36 is heavier with a bigger rig. Here in the PNW the 35 rates 72, the 36 rates 79. The 36 was a tough boat to beat in Vic-Maui races, although that might have been a rating thing.
The 18hp diesel engine is located in the center of the boat, functioning as the main cabin table, too. There are quarterberths to both port and starboard. Pipe berths were offered above each of the main settee berths to accommodate crew for offshore distance races.
