ABSTRACT:
A boat hull is disclosed having a bow and a stern. The hull includes a pair of elongated sponsons, each having a lower surface adapted to contact a water body having a water level. The sponsons are spaced apart and generally parallel to each other and form a channel therebetween. An aerodynamic member is positioned within this channel. The aerodynamic member includes an air compression section which slopes downwardly from the bow to a midpoint of the hull. Similarly, an air decompression section slopes upwardly from the midpoint of the hull and towards the stern. In operation, the aerodynamic member is dimensioned such that, upon forward movement of the hull through the water body, the compression of air flow through the channel by the air compression section and subsequent decompression of the air by the decompression section is sufficient to elevate water in the rear portion of the channel above the water level of the water body.
