Abstract
A water craft having a motorcycle suspension which makes the craft more maneuverable and, therefore, safer to ride especially over rough and choppy water at high speeds. It also has plural flotation tanks to provide a margin of safety if one of the tanks is punctured. The water craft also has a rear brake spoiler to slow the craft down so the operator will not have to rely on the resistance of the water to bring the craft to a halt.

- steering means for enabling a user to change directions of said water craft,
- said steering means having a steering column thereto,
- a front ski assembly connected to said steering column,
- said front ski assembly including at least upper and lower front skis,
- each of said upper and lower front skis having a front portion on a front side of said steering column and a rear portion on a rear side of said steering column,
- said front ski assembly including means supporting said upper and lower front skis on said hull for pivotal movement about a steering axis in order to steer said water craft,
- said front ski assembly being supported by at least a pair of pivoted links,
- said links being attached between said rear side of said steering column and said rear portion of said front skies,
- a rear ski assembly underlying a rear portion of said hull and including at least upper and lower rear skis,
