Abstract
A mid-planing hull for a fast, sea-going vessel in which the centers of buoyancy, gravity, and hydrodynamic lift at planing speeds substantially coincide amidships. In a preferred embodiment, the hull includes a full forefoot of conically developed forward sections, a straight and level keel in a vee-bottom of constant deadrise, with planing surfaces distinctly decreasing in area in the afterbody to trailing edges at the stern.
