Abstract:
A boat lift comprising:a base anchored adjacent a shoreline of a body of water; a frame structure for raising a boat from the water and lowering a boat into the water, the frame structure including: a swinging frame having inner and outer ends, the inner end swingably attached to the base by a first swinging coupling, and a boat-supporting frame having proximate and remote ends, the proximate end swingably attached to the swinging frame by a second swinging coupling adjacent the outer end thereof, a section of the boat-supporting frame disposed adjacent the remote end thereof defining a boat supporting structure arranged to support an underside of a boat; an actuator operably connected to the frame structure for causing the swinging frame to swing relative to the base about the first swinging coupling, wherein the boat supporting frame moves upwardly and inwardly toward the base to a boat-storage position when the swinging frame swings in one direction, and wherein the boat-supporting frame moves downwardly and outwardly away from the base to a boat-launch position when the swinging frame swings in an opposite direction, wherein the boat-supporting structure remains in a substantially horizontal state during up-and-down movement of the boat supporting frame; and the frame structure forming a walkway arranged for providing users with access between the shoreline and the boat-supporting structure when the boat-supporting frame is in its boat-launch position.
