ABSTRACT:
A pair of lifting planes are secured to the hull of a boat on opposite sides of the keel. The lifting planes intersect the bottom surfaces of the hull at lines oriented generally along side the keel. The lifting planes have swept back leading edges and a span generally reaching to the chines. The outboard portions of said lifting planes are located at or adjacent to the longitudinal location of the center of gravity of the boat. The longitudinal location of the lifting planes is such that the resulting lifting force generated by the lifting planes at planing speeds acts adjacent to the center of gravity of the boat.
