Abstract

An aquatic recreation vehicle susceptible to use by one or a group of passengers or crew has an integrally formed hull having a plurality of surfaces. The hull is symmetrical about a central vertical symmetry plane which essentially divides the hull longitudinally in half. The surfaces include at least three longitudinally extending sections and at least two longitudinally extending pressure ridges. The pressure ridges are symmetrically located on the bottom of the hull and are inwardly directed toward the vertical symmetry plane. At least two longitudinally extending runners are located on the hull to provide high speed planing lift. The hull surfaces are curved upward at the bow to provide smooth entry into the water. A superstructure is located on the hull and extends longitudinally along a portion of the length of the hull. The combined centers of gravity and buoyancy of the hull and superstructure normally lie essentially in the same vertical symmetry plane. The superstructure includes a longitudinally oriented crew seating member which the crew members straddle one behind the other along the length of the superstructure. During turns the crew are able to shift their center of gravity toward the apex of the turn depressing the pressure ridge on the side of the vehicle toward the apex of the turn to control the vehicle in the turn.

Dependent claims

An aquatic vehicle capable of buoying and transporting one or more crew members which comprises:

a hull symmetrical about a longitudinally extending, centrally located, vertical symmetry plane;
said hull having a plurality of integrally formed longitudinally extending surfaces;
said surfaces including at least three longitudinally extending sections and at least two longitudinally extending pressure ridges symmetrically located to the right and left of said vertical symmetry plane, each of said pressure ridges downwardly and inwardly directed toward said symmetry plane, each of said pressure ridges interspaced between two of said hull sections;
said sections of said hull and said pressure ridges curving outwardly and downwardly from the fore end of said hull and extending backwardly to the aft end of said hull said pressure ridges diverging from points adjacent said symmetry plane at said fore end;
said hull including a deck forming the uppermost surface of the hull;
a longitudinally extending superstructure located over said hull extending along a portion of the length of said hull upwardly from said deck;
said vertical symmetry plane dissecting said superstructure along its longitudinal axis into essentially symmetrical right and left side halves;
the combined centers of gravity and buoyancy of said hull and said superstructure normally lying essentially in said vertical symmetry plane;
said superstructure including a longitudinally oriented crew supporting means located above the center of buoyancy of said vehicle, and projecting upwardly from said deck, said deck extending from said crew supporting means outwardly to the right and the left of said vertical symmetry plane, said crew supporting means sized and shaped to allow one or more of said crew members to individually straddle said supporting means such that if two or more crew members occupy said vehicle, said crew members are aligned tandemly one behind the other along the length of said supporting means and each of said crew members independently can sit astride said crew supporting means with their legs projecting downwardly and outwardly towards said deck with their feet locatable on said deck;
said crew members capable of freely shifting their center of gravity from a position directly over the center of buoyancy of said vehicle to positions to the right or left of a point directly over the center of buoyancy of said vehicle such that when the center of gravity of said crew is shifted to the right or left of a point directly over the center of buoyancy of said vehicle, said pressure ridge located on said side of said vertical symmetry plane to which said center of gravity is shifted will be depressed downwardly with respect to the static water line of said vehicle.
