ABSTRACT:
A pair of skis are attached along either side of an outboard marine vehicle and are used to smooth the ride of the marine vehicle by decreasing resistance between the vehicle and water. Each ski is attached to the marine vehicle by a coil spring, a shock absorber, and a trailing arm connected at a substantially central pivotal point on the ski and further attached to a mounting plate on the side of the vehicle. The coil spring provides for a resiliency of the ski with respect to the marine vehicle, and substantial impacts between the water surface and the marine vehicle are absorbed in the spring, with the shock absorber damping out excessive vibrations. The trailing arm prevents substantial movement of the ski in a horizontal plane with respect to the marine vehicle, and a further elastic member or spring is attached to a front portion of each ski and the marine vehicle to ensure that the tip of the skis will not inadvertently fall below the surface of the water.
