ABSTRACT:
A jet ski hull includes upper and lower sections joined along a peripheral edge which edge is arranged to extend above the nominal waterline. In accordance with the present intention the lower hull section comprises (1) a central section extending from the bow of the ski to the stern thereof, 2) a concave section disposed on each side of the central section, (3) a pair of side walls joined to the upper hull section of the peripheral edge and extending downwardly and inwardly from the peripheral edge and (4) a transition section joining the lower portion of each side wall to a respective concave section. Each concave section defines a channel extending substantially the length of the hull for channeling water therethrough to prevent the hull from skidding during turns.
