A lift-generating device for a power boat includes a boundary (4) of semi-circular form in cross section mounted beneath the propeller (5) of the boat so that the propeller (5) produces a high-speed water flow over the upwardly facing surface of the boundary (4), thereby creating lift.
[ What is claimed is:] [1.] A lift-generating device for a boat having a flow generator (5) for generating a high-velocity stream of water, which device includes a boundary (4) having an upwardly facing surface and a downwardly facing surface, means for mounting said boundary so that said high-velocity stream of water is caused to flow over said upwardly facing surface at a velocity greater than any flow of water under the downwardly facing surface of said boundary, and in which the boundary (4) extends both upstream and downstream of the flow generator ...
