  • Patent number: 4101997
    Abstract: A water ski particularly adapted to function as the front ski of a twin ski, jet-driven water vehicle which is steered by turning of the front ski. Sections of the water ski define a planing surface and a pair of inclined, laterally spaced side surfaces extending downwardly and laterally of the planing surface. The portions of the side surfaces lying in or cut by a horizontal plane are equidistant from each other when the planing surface is upwardly tipped at a predetermined angle. At this angle the pair of juncture lines formed between the pair of inner surfaces and the planing surface are laterally divergent in a downstream direction when viewed from above. Reduced frontal drag results.
