Abstract
The present invention is generally directed to a floating watercraft lift capable of raising and lowering a watercraft, and more particularly to a floating watercraft lift. In one embodiment, the watercraft lift includes a pair of longitudinally extending and approximately parallel floats with an apparatus for supporting and lifting the watercraft positioned between the floats. When the watercraft lift is positioned in a lowered position, the apparatus is submerged and each of the floats is in a first orientation and partially submerged. The apparatus may then be activated to move the watercraft lift to a raised position by moving the floats downwardly and inwardly towards the watercraft, so that the floats become further submerged in the water. The buoyancy of the submerging floats thus lifts the lift apparatus and the watercraft above the water surface.
