ABSTRACT:
A high-speed, ultrastable, wind propelled watercraft employs an airfoil for propulsion and buoyant hydrofoils for support. A buoyant keel/rudder is rotatably mounted to a boom which horizontally projects from near the base of the airfoil. Both the airfoil and the keel/rudder steering axis are inclined from the vertical substantially in parallel. The particular orientation, freedom of movement, and shapes of the various foil, support and control surfaces enhances the maneuverability of the craft and allows the craft to be sailed at most pointing angles.
