ABSTRACT:
The invention is directed to a watercraft hull design that comprises a hull having a bow, stem, top, and bottom. A wedge-shaped wave spreading system is located at a forward portion of the craft. The wave-contacting surface planes of the wave spreading system are positioned substantially perpendicular to the plane of smooth water. The bottom edge of the wave spreading system is positioned near the level of smooth water when the watercraft is at cruising speed. The wave spreading system has a forward apex which forms a substantially perpendicular or vertical leading wedge to the plane of water. Since the apex and planes of the wave spreader are substantially perpendicular to the water, oncoming waves encountered by the wave spreader will tend to be deflected horizontally. Accordingly, the watercraft will more easily “cut through” waves instead of riding over them. Located rearwardly of the wave spreader, an internal hull prow is spaced from the wave spreading system, creating an air space therebetween. The air space extends from the rearward surface of the wave spreader to the front of internal hull prow, creating a buffer zone or dampening space to further minimize any wave action not detected by the spreading system.
