F-36 at Porto Santo Island, North Atlantic

The F-36 is a large, ocean going, cruising multihull, with the capability of being demounted (not folding) for occasional trailering at 10′ (3.05m) wide. This gives tremendous versatility for an ocean capable boat.

The trimaran’s superior handling and performance makes it the knowledgeable sailor’s cruiser of choice. Other advantages include a drier ride, with no immersed windward bow to throw back spray, no problems with wingdeck pounding, nor is a high windage boxy cabin required for standing headroom.

The fractional rig is efficient and easy to handle in all conditions, and the boat can be sailed to its full potential with a minimum of sails. A self-tacking jib is optional with the centerboard version and boom can be roller furling. A wire luff genoa (Screacher) set from the bow pole, eliminates the traditional genoa and multiple sail changes, making sail handling a breeze. It’s even more ideal for cruising. Rig size is conservative and this coupled with the F-36’s enormous 108,000 foot-lbs righting moment, gives a very safe cruiser.

Daggerboard or centerboard are optional, while a kick-up spade rudder is housed in its own retractable rudder box in the transom. Wheel steering is standard, but a tiller is optional with the aft cockpit version. The self-draining center cockpit can seat six adults, aft cockpit eight to ten.

An inboard of 20 to 30HP is recommended, located in a roomy and accessible area under the cockpit. Maneuverability is excellent under power, due to the trimaran’s superior turning ability, its center hull and daggerboard being natural pivots.

The beams are demountable, to give an occasional trailering capability at 10′ (3m) wide. The strut reinforced beams eliminate the need for full width beams, increasing interior room. The beams are smaller, lighter, easier to demount, and allow standing headroom between the forward beams.

Interior can accommodate six to eight, with standing headroom throughout. Galley is to port, and a chart table is on the starboard side, along with a wet locker. Dinette will seat five, and can be converted into a large double bunk. Starboard settee is wide and comfortable, and can be converted into top and bottom bunks.

Forward, there is a private bathroom with head, washbasin, and a separate shower. Forward cabin has a double berth, with seating room aft, and large storage areas underneath. The aft cabin has a double or two single berths with full sitting headroom. Access is through a hatch in the aft cabin front, or through under the cockpit.

An optional pilothouse can shelter the cockpit, giving standing headroom to the forward end of the aft cabin, and an all weather passage to the main cabin through the cockpit. The optional aft cockpit version gives even more main cabin space, while the cockpit size is considerably increased, with easier access over the stern.

Material or building options include both vertical stripped foam and strip planked Cedar or Durakore®. As with all Farrier designs, a monocoque structural system is used, with interior panels being designed to absorb and distribute structural loads making the hull a very efficient, strong, and light unitary structure. The connecting beams are made from either fiberglass or carbon fiber with foam core.

F-36 plans are being regularly updated, and many new features that are have been incorporated in the F-39 are available on request to keep the F-36 a ‘state of the art’ design. These include the F-39 carbon fiber chainplates, rotating mast, and daggerboard rudder option.

Assembled – it took two people 6 to 8 hours to put this F-36 together, with the help of a fork lift (works better than a crane). Demountables will always take considerably more time compared to a built in folding system and are not intended for frequent trailering. Practice will improve assembly to around 3 to 4 hours. However, be wary of any claims that it just takes a couple of hours to put a boat of this size together. A crane or fork lift is not necessary but will be of help.
