ABSTRACT:
A hydrofoil sailboat having a sailing frame that is secured by swivel connection to a conventional hull, the frame comprising a plurality of prestressed interconnected spars, guys and a sail, a pair of buoyant hydrofoils, one at each of the leeward extremities of the frame, and a single manually operable tiller situated at the hull for governing the direction of movement by articulating the hydrofoils in accordance with the point of sailing and the direction of the wind. The tiller is operatively associated with the hydrofoils through pairs of spreaders and multiple cables. The sail is inclined to the vertical axis, and is tightly stretched to define an air foil spaced laterally away from the hull. The crank adjusts the inclination of sail and the hydrofoils cancel out listing moments. The sail frame exerts a towing force on the hull.
