ABSTRACT:
A free floating fully self contained boat lift has two floats which support a cantilever lifting device. The floats support the weight of the lift and the boat and always remain afloat. The cantilever lifting device has two hydraulic rams operated by water at household pressure. The rams raise and lower a cantilever which supports the boat hull. Once the lift is raised, it is locked in place by a locking mechanism. A pair of control valves regulate water to the rams.
