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.
