The view forward on an F-27 - plenty of deck room

Totally Unsinkable - due to materials used - hulls are all foam or wood, and there's NO LEAD.
Puncture all three hulls and your Farrier design will still float!

Stability - unmatched by any other type of craft.

Level Sailing - the low heel angles set new standards of comfort for family sailing.

Deck Space - a paradise when combined with level sailing, and easy motion. You can actually take a stroll around the decks.

Handling - the light finger tip controlled helm, the dinghy-like tacking of trimarans, coupled with high stability, and lack of vices like uncontrollable broaches make the multihull always a pleasure to sail.

Shallow draft - opens up many previously out of reach cruising grounds, while any beach is easily accessible.

HULL LINES: The hull underwater sections begin with a very fine entry, flowing back to a U-type midsection, followed by a broad flat run aft. Rocker is kept to an absolute minimum for less drag and to encourage early planing. This unique feature was pioneered by the F-27 trimaran and is now standard with all F-Series® trimarans, and similar lines are now being used with catamarans.

The planing ability of the low rocker trimaran center hull also allows a wider hull section to be used, for more room inside, while still retaining excellent performance.

Farrier trimarans have always used a roomier wider center hull since it was discovered with the original Trailertri 18 that a narrow hull was not necessary for high speed sailing. This is made possible by the center hull lifting as the boat heels, rapidly reducing hull width, until the hull is planing on the flat lower sections, avoiding any restricting hull speed. In fact the wider planing hull seems more efficient at higher speeds, while also providing a considerably higher load carrying capacity, and less wetted surface for superior light wind performance.

When going to windward, the sharp hollow entry cuts through waves effortlessly, while the bottom area just aft of the forefoot is kept relatively narrow to minimize pounding to weather.

The flat transom prevents stern burying, to quickly damp out pitching. The proven ability to handle short steep chop without hobby horsing is a well proven characteristic of all Farrier multihulls.

At high speed, the trimaran main hull planes early due to the low rocker, while the swept up aft section generates negative lift, which can actually lift the bow well out of the water. As a result, Farrier multihulls are very resistant to bow burying.

Another advantage of the long lean low rocker hull is the straight tracking for easy control at high speeds. A hull with too much rocker can resemble a bowl, which does not have good directional characteristics.

TRIMARAN FLOATS: The high buoyancy floats provide incredible stability, minimizing heel, and making heavy lead ballast unnecessary. They are designed with buoyancy initially located aft, to counter the tendency of the main hull bow to lift, but then the buoyancy moves rapidly forward as wind pressure increases, to counter the forward pressure of the sails, helping the main hull bow to stay high. For safety, float decks are well rounded to quickly shed any water, and for low drag. An essential feature for all modern trimarans. Sterns are also kept fine so they can sink into large waves coming from astern on the quarter. This helps eliminate any downward force that can be transferred to the float bow by wide float sterns in this situation.

TRIMARAN BEAMS: are set high for excellent wave clearance, while overall beam is not excessive. This avoids the additional windage and weight from longer beams, that will then need to be stronger and heavier.

There is a point where wide beam will only slow the boat down, while fore and aft stability becomes proportionally less, creating fore and aft stability problems. Correct overall beam will give a 'balanced', easy to control design, with no handling or other vices.

RIG: Efficient and balanced design, means there is no need for an oversize rig, with more added windage and weight, and all Farrier multihulls make great cruisers, while still being fast enough to even surprise the extreme racers.

Mast is now rotating as standard in all designs, and this combined with a square top fully battened main and blade jib form a very efficient combination.

SPINNAKER: Asymmetric spinnakers are now also used on all designs, for their ease of use and greater efficiency.

SCREACHER: an upwind and downwind sail, with a wire or torque line luff, set inside the spinnaker to the bow pole and roller furled. An efficient and exciting sail that can make both spinnaker and genoa unnecessary.

KEEL: High aspect daggerboards or centerboards are used to efficiently prevent leeway.

RUDDER: Either transom hung or underslung rudders are used, and each can kick-back if running aground. Foil section is designed to provide high lift for a quick response, while discouraging ventilation at very high speeds
