Abstract
In a personal recreational watercraft, an improvement resides in a suspension mechanism, which permits greater maneuverability and stability, and reduces driver fatigue. To overcome the strong forces, a suspension system is employed which permits up and down vertical movement, while resisting lateral movement and torsional forces. The suspension apparatus also reduces shock effects caused by choppy or rough water.

A watercraft with a suspended upper deck body comprising:
- an integrally molded upper deck body;
- an integrally molded lower hull body;
- a flexible collapsible waterproof membrane connecting said hull to said upper deck body;
- said membrane being fixedly attached to the peripheral upper edges of said hull and the lower peripheral edges of said upper deck body;
- said upper deck body including a bow deck, side decks, a steering console, an operator's seat, a rear deck and a pair of rear footwells, all of which are integrally molded to one another in fixed relation;
- said upper deck body being supported in suspended relationship to said hull by at least one resilient spring and damping means and at least one support arm means;
- and
- wherein in operation said resilient spring and damping means is adapted to absorb shock while said support arm means is adapted to resist lateral and torsional movement of said upper deck body in relation to said hull.
