Claims48
A planing hull comprising a bow, a stern, a fore portion, an aft portion, an upper deck portion and a lower hull portion, said lower hull portion further comprising a substantially T-shaped bottom face, said bottom face substantially comprising the lower hull portions of said fore portion and said aft portion, said fore portion comprising said bow tapering outwardly toward said stern to a point proximal said stern, said aft portion comprising said stern extending to said point proximal said stern, said bottom face of said lower hull portion of said fore portion gradually curving upwardly toward said bow and further comprising a centerline formed in said bottom face of said lower hull portion, said bottom face of said lower hull portion extending outwardly from opposite sides of said centerline forming a V-shaped bottom face.
A planing hull comprising a bow, a stern, a fore portion, an aft portion, an upper deck portion and a lower hull portion, said lower hull portion further comprising a substantially T-shaped bottom face, said bottom face substantially comprising the lower hull portions of said fore portion and said aft portion, said fore portion comprising said bow tapering outwardly toward said stern to a point proximal said stern, said aft portion comprising said stern extending to said point proximal said stern, said bottom face of said lower hull portion of said fore portion gradually curving upwardly toward said bow and further comprising a centerline formed in said bottom face of said lower hull portion, said bottom face of said lower hull portion extending outwardly from opposite sides of said centerline forming a V-shaped bottom face, at least one cockpit formed in said upper deck portion, at least one compartment formed within said upper deck and said lower hull portion, said compartment further comprising an opening in said upper deck for receiving a power source, said hull further comprising at least one watertight hatch for sealing said opening, and a power source mounted in said compartment;
- a means for accelerating water sternward disposed within said hull and an intake means communicating with a body of water on which the hull is located for providing water to the means for accelerating water, a means for connecting said power source to said means for accelerating water sternward, a means for steering said planing hull and a throttle means operatively connected to said power source and controllable by an operator of said planing hull.
A watercraft comprised of a fore portion having a longitudinal centerline and opposing longitudinal sides that extend from the watercraft bow symmetrically around said centerline to a point of maximum width;
- an aft portion having a width one-fifth to four-fifths the width of the point of maximum width of the fore portion;
- and
- a transition section between said fore and aft portions.
