 A human-powered hydrofoil racing-boat: Design and developmentD.J. Owers and S.D. Probert Applied Energy, 1985, vol. 21, issue 4, 289-300 Abstract: A human-powered, hydrofoil-supported, racing boat has been designed, built, tested and developed. At relatively high speeds ([greater, approximate]4ms-1), this craft provides a more energy efficient means of transport than a conventional displacement hull. An athlete should be capable of powering such a hydrofoil boat through its [`]take-off' speed of approximately 3·6 ms-1, and then in its [`]foil-borne' mode of operation, be able to achieve record speeds exceeding 6·0 ms-1. The prototype hydrofoil-supported craft, built for this investigation, required about 287 W of effective power to [`]take-off', i.e. for the weight of boat plus driver to be entirely hydrofoil-borne, so that the hull was lifted completely out of the water. Due to employing an inappropriate propeller (of only ~57% efficiency) and at least 16% excess weight for the boat plus chosen human driver, he could power the craft only to 3·5 ms-1, at which speed the hull had risen so that all but the lowest 5 cm depth of it was above the water. With further developments human-powered hydrofoil craft will fully take off.
