F101 Foiling Trimaran

F101 takes you through your foiling journey, providing a progression pathway from the beginner foiler to the Olympian. F101 sets new challenges and goals at whatever level you come in; from expert to beginner.

The F101 is an all new foiling trimaran, aimed specifically at those sailors that, for whatever reason, thought foiling was too difficult for them. The concept originates from the experience of teaching many people to foil in the international Moth class, and addressing the main barriers they faced. So we set about creating a new boat without the design restrictions of a box rule – in this way foiling has been made easier.

Why three hulls?

Many Moths use buoyancy in the wings to help sailors get to grips with the boat, but this buoyancy is limited to helping the helm recover the boat from a capsize and does little to prevent the capsize in the first place. The F101 Tri-configuration allows for a slender hull with enough length to prevent pitch poling, while at the same time creating a stable platform to allow novices to get out on the water with no previous foiling experience.

The super slender wave-piercing outer hulls are set at an optimum angle to initiate foiling – simply sit on the windward hull, which will cant the boat to windward, then sheet in and take off! If the F101 does pitch forward, the main hull is designed to recover straight back onto the foils; the hull’s additional length keeps the angle of incidence shallow. Its rocker is matched to the angle of incidence – and the additional buoyancy forwards help lift the bow. The benefit applies to the outer hulls too – if the F101 falls in to windward, the windward hull lifts the boat back out. If the boat falls in to leeward there is enough buoyancy to prevent a capsize and the boat is quickly back on the foils.

Design Features

  • All carbon construction: main hull, foils, floats, beams, 2 piece mast.
  • Very simple, well thought out control systems.
  • While being designed to be a single handed boat, you are able to take a friend out for a fun sail, hence the 1+1.
  • The boat is stable in non-foiling mode so that if the wind drops it is easy to sail home.
  • Long, central hull places the rudder and main foil further apart, removing some of the limitations and bad habits that other foiling boats suffer from.  The hull is long enough to prevent nose diving.
  • The foils retract so that the boat can be launched from a launching dolly in shallow water.
  • The mainsail can be hoisted by halyard and, crucially, the sail easily drops when coming on to a lee shore.
  • While being designed to be a single handed boat, you are able to take a friend out for a fun sail, hence the 1+1.
  • The boat is stable in non-foiling mode so that if the wind drops it is easy to sail home.
  • Option of a furling downwind sail, to give extra power and an added excitement if needed in lighter airs.
  • Learning to foil in most monohulls can be very tiring, due to repeated capsizes. The F101 design is very hard to capsize!
