ABSTRACT:
A boat lift includes a pair of straps or ropes which are secured at one end at intermediate elevations along a pair of horizontally spaced upright standards. The straps extend downwardly beneath a boat and then upwardly where they are secured about pulleys mounted on a horizontal shaft journaled at the top of the standards. Rotation of the shaft by a handwheel will shorten the straps and lift and completely overturn the boat.
