In a lift (L) for mooring a boat (B) stern-on, a pair of horizontally spaced guide members (19,21) is fixed to the sea wall (S). A frame (23) is fixed to a pair of substantially parallel hydro-pneumatic buoyancy tanks (11,13) to provide a flotation platform for supporting the hull of the boat (B). The stern end of each of the tanks (11,13) is connected to the guide members (19,21). The guide members (19,21) limit movement of the lift (L) away from the sea wall (S) and along the sea wall (S) but permit vertical reciprocation of the stern ends of the buoyancy tanks (19,21) in unison and restrict the lift (L) from listing during operation. <IMAGE>
