Abstract: A watercraft lift for raising and lowering a watercraft in water, including a buoyant pontoon, a lifting cradle and at least one pivot arm. The lifting cradle includes at least one air tank and a support bunk configured to receive and support the watercraft. The air tank has an internal chamber configured to receive and release pressurized air. The internal chamber has sufficient internal volume that when sufficient pressurized air is received therein the air tank has sufficient buoyancy to lift the lifting cradle to a raised position with the watercraft out of the water when positioned on the support bunk and that when sufficient pressurized air is released from the internal chamber the air tank loses sufficient buoyancy to sink the lifting cradle to a lowered position sufficiently submerged to receive and deploy the watercraft.

Abstract: The invention generally relates to an apparatus and method that allows the lifting range of a four-bar, ground-based watercraft lift to be adjustable. More particularly, it relates to a ground-based watercraft that that allows for the lifting range of a watercraft support structure to be adjustable relative to the base of a watercraft lift while also maintaining the lift's shallow water functionality.

Abstract: An apparatus and method for covering a watercraft with a self-adjusting watercraft cover coupled to a watercraft lift is disclosed.
