ABSTRACT:
An assembly for lifting a boat locatable adjacent a dock requires only two elongate vertically disposed pilings each having a lower end portion mounted into the floor of a body of water near the dock and an upper end portion extending upwardly adjacent the dock. A lift is connected to a boat cradle for moving the cradle substantially vertically and includes a piston/cylinder attached between the dock and cables, which are mounted to each piling and are connected between the piston and the cradle. The piston is movable between a first position for lifting and pulleys and guides are mounted to the pilings and the cradle.
