ABSTRACT:
A float-on boat lift for pleasure craft has a substantially rectangular, open-ended support framework adapted to project outwardly of a dock facility or seawall, within which framework is pivotally secured, at one end, a float-on boat cradle. Winch mechanism supported at the inner end of the cradle framework and at approximately dock level includes cables extending along each side of the cradle framework serving to raise and lower the rearward end thereof out of and into the water for dry docking or launching of a boat previously floated thereupon while in its lowered position. The cradle comprises lateral guides and bottom chocks distributed along its length to facilitate the loading and seating thereon of a boat preparatory to its being lifted out of the water.
