A pleasure boat for operation at high speeds in moderate seas, and having a rectangular passenger area, planes on ski-like planing surfaces on the bottom of laterally spaced, knife edge hulls located on the starboard and port sides of the craft. The boat has a centrally symmetrical wedge commencing at the forward transom of the boat and extending to about the beginning of the planing region toward the stern of the boat and a relatively thin plate extending preferably cantilevered, from the bottom surface of the wedge to a sufficient distance forward of the rear transom to accommodate a propeller. The plate is held in a normal position by shock absorbers and a drive shaft from an inboard engine extends through a vertical wall formed by termination of the wedge to a propeller at the stern of the craft, the shaft lying between the bottom of the boat and the plate.

A high speed, high efficiency planing boat comprising: a passenger compartment having a bottom, a pair of forward hulls depending downwardly from said bottom of said passenger compartment, said hulls being spaced apart and lying on opposite sides of the longitudinal centerline of said boat, each said hull having a ski-like surface toward the rear thereof, a wedge-shaped member having a bottom surface and extending downwardly along said bottom of said passenger compartment with its apex lying between said hulls along the longitudinal centerline of the boat, a plate of predetermined length, said wedge shaped member terminating at a distance from the stern of said boat approximately equal to the length of said plate, said plate extending from at least the rear of said wedge shaped member to near the stern of said boat to provide a planing surface for said boat, and means for normally holding the said plate in a continuous plane with the bottom surface of said wedge shaped member and cushioning movement of said plate toward said bottom of said passenger compartment.
