Abstract
A small outboard motor powered boat comprises a hull undersurface that defines a generally flat central section, with two generally parallel-sided pontoons extending rearwardly from an upturned bow to a point about half the length of the hull aft. A stern rake section begins at a transverse line near the transom of the hull and forms a downward angle with respect to the flat central section. At speed, air is entrained between the pontoons, providing lift to the bow of the vessel, while the after portion is supported by the stern rake section. Thus, the vessel effectively rides on the pontoons and the stern rake section, reducing wetted surface and thus improving efficiency. The downwardly-extending lengthwise sides of the pontoons provide lateral surface, providing good steering characteristics.
