ABSTRACT:
A lightweight, high strength, water ski hydrofoil assembly includes a diamond planform hydrofoil wing and a V-strut connecting the wing to a parallel ski support platform. The diamond planform wing is formed as a unit and the separately formed V-strut and platform secured thereto. The wing is provided with a foam plastic, aluminum or composite core element, while the V-strut and platform are provided with core elements selected from aluminum or aluminum alloys, composites and balsa wood. In the preferred embodiment, the core elements are provided with an intermediate layer of molded composite material (resin impregnated fiberglass and graphite fibers, or cloth) and an outer layer of rubber. The rubber coating may be applied to the core elements by injection molding, and confined to the leading and trailing edges of the components, with the intermediate layer being omitted, in some embodiments.
