Wind driven hydrofoil watercraft

Claim 1

A wind driven watercraft comprising a buoyant hull having a fuselage frame and capable of floating on water when the craft is stationary, a singlebladed side-hydrofoil depending radially outwardly from each side of the hull in a continuously diverging direction relative to each other and at an angle below the horizontal when the craft is stationary whereby said side-hydrofoils form an inverted V-shaped configuration, said side-hydrofoils being positioned forwardly of the center of gravity of the watercraft, a single blade front hydrofoil mounted centrally between said side-hydrofoils and depending vertically downwardly from said hull, said side-hydrofoils being pivotally mounted with respect to the frame on pivotal mountings to enable the ends of said hydrofoils to be movable towards the hull about the pivotal mountings and to enable said side-hydrofoils to be pivoted independently of each other about their longitudinal axes during wind driven operation of the watercraft, a rear hydrofoil depending downwardly from the hull, said rear hydrofoil being pivotally mounted with respect to the frame and capable of moving in a clockwise and anti-clockwise direction about its longitudinal axis to steer the craft, means for enabling wind to drive the hull forward, a cockpit towards an upper part of the hull and control means in the cockpit and linked to the side and rear hydrofoils for enabling the position of the side and rear hydrofoils about their pivotal mountings to be altered, said craft being capable of being supported and traveling on the hydrofoils when in motion.
