Abstract
A lift for watercraft has raised and lowered positions and is adapted to be mounted in a body of water. The lift has a substantially rectangular base with first and second pairs of vertical corner posts that are connected to and carry longitudinal beams. The base further has two transverse beams connected to the longitudinal beams. A pivoting cradle is attached to the base. Watercraft support bunk are connected to the cradle. A pair of actuators is connected on one end to the pivoting cradle and on the other end to one of the first pair of corner post. The first pair of corner posts is adapted to be long enough that at least a portion of the corner posts is above a water level of a body of water in which the lift is mounted, and the actuators are connected to the first pair of corner posts in the portion of the corner posts above the water level.
