Abstract:
1. 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; said at least one fore hull portion having a generally V-shaped overall exterior surface topography and said at least one aft hull portion 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, laterally centered, downwardly opening 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, wherein a forward extent of each said at least one topographic feature is disposed along a lateral side of the hull, said at least one topographic feature influencing air to flow from open atmosphere to the recess entirely along the external surface of the hull.
