ABSTRACT:
A water and air supported vehicle propelled by the wind. The vehicle includes a long narrow hull (30) that displaces water at low speeds and a plurality of hydrolfoils (36) distending from the hull in communication with the water resisting lateral loads and at high speeds partially supporting the vehicle. An airfoil (38) whose section is suitable for a membrane surface is pivotally attached to the hull and acts to partially support and provide thrust to propel the vehicle. A strut and a plurality of tendons (58), (60), (62), (64) and (72) position the airfoil relative to the hull (30) and articulate the airfoil when manually actuated. The shape of the airfoil tips elements (46) provide vehicle roll resistance when they penetrate the water surface and a payload is supported by a hull torque link (66) and a cantilever beam (90) with a sling (92) positioned therebetween. Other embodiments articulate the hydrofoils in concert or include a payload containing capsule (112).
