Patent ID: 6837176

Claim:
A vessel having a bow, a stern, an amidships, a port side, a starboard side, and a topside, the vessel comprising: a transition hull disposed opposite the topside between the port side and the starboard side and configured to contact a water surface to hydroplane the vessel on the water surface at a high speed and displace the water surface at a low speed, wherein the transition hull extends from a convergence point in contact with the water surface proximate the amidships and diverges away from the water surface to terminate at the stern apart from the water surface to respectively form a port sponson, a starboard sponson, and a wash area therebetween, and wherein each sponson defines a forward end, an after end, and a wash area face, the respective forward ends converging at the convergence point, the respective after ends diverging away from the convergence point and the transition hull along the water surface in a direction of the stem such that each sponson forms a respective running surface in contact with the water surface, the respective running surfaces and respective wash area faces configured to create a vortex in the wash area to disrupt a flow of water when the vessel is traveling at the high speed.
