ABSTRACT:
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.
