ABSTRACT:
A floating boat lift for lifting and supporting a boat above the surface of a body of water. The boat lift includes two elongated buoyant pontoons held in spaced apart, generally parallel relation by two transverse, generally U-shaped supports. Each transverse support has a lower, elongated mid portion, side portions upwardly extending from the ends of each mid portion, and upper horizontal end bearing portions which outwardly extend for pivotal connection with the respective pontoons. A cable mechanism is connected between a winch and the transverse supports whereby the supports are pivoted between a first position wherein a cradle connected to the mid portions is elevated above the water's surface and a second position wherein the cradle is submerged. Movement of each mid portion is along an arc defined generally by the length of side portions of each support.
