Abstract
In a lift for mooring a boat stern-on, a pair of horizontally spaced guide members is fixed to the sea wall. A frame is fixed to a pair of substantially parallel hydro-pneumatic buoyancy tanks to provide a flotation platform for supporting the hull of the boat. The stern end of each of the tanks is connected to the guide members. The guide members limit movement of the platform away from the sea wall and along the sea wall but permit vertical reciprocation of the stern ends of the lift tanks in unison and restrict the lift from listing during operation.
