发明名称 Steerable, towable flotation device
摘要 The present invention is a water sport device that is easy to use and may be steered. This device comprises a flotation assembly, a connecting member, and a connecting assembly, where the connecting member is attached to a front portion of the flotation assembly. The connecting assembly moves along the connecting member to change an effective attachment point of a towline to the flotation assembly. Sponsons are preferably arranged on the underside of the flotation assembly. These sponsons are preferably toed in to provide a rearwardly diverging channel between them. Outer surfaces of the sponsons are outwardly and upwardly canted to allow the entire device to move side to side in the water. A handle assembly is provided that allows the rider to move the position of the connecting assembly relative to the connecting member.
