Patent ID: 7677192

Claim:
A hull arrangement for a surface riding marine vessel comprising: a marine vessel hull having an exterior surface, said hull including at least one fore hull portion and at least one aft hull portion; at least one of said fore hull portions having a generally V-shaped overall exterior surface topography and at least one of said aft hull portions having a generally slot-V exterior surface topography, said fore hull portion V-shaped overall exterior surface topography extending across a substantial majority of said vessel's beam and said aft hull portion slot-V exterior surface topography approximating a V-shape modified by a slot aspect formed into said aft hull portion's underside, said slot aspect including a longitudinally extending, downwardly opening recess, wherein said recess is substantially disposed within a longitudinally extending slot recess region, said slot recess region substantially spreading about one sixth of the vessel's beam in a vertical direction and one quarter of the vessel's beam in a transverse direction, said slot recess region also generally disposed along a longitudinally centered contour of the hull's underside, and said recess is essentially devoid of any interrupting element so as to provide uninterrupted free flow of fluid through the recess; said hull exterior surface including at least one topographic feature that at least partially extends appreciably forward of the slot aspect of the aft hull portion, said topographic feature facilitating ventilation of the slot aspect recess, when the marine vessel is in forward motion through the atmosphere, by aerodynamically influencing a part of the atmosphere to provide a ventilating airflow that accesses the region of the slot aspect.
