Abstract
A floating boat lift having 2 side support frames and a front frame with a central region for docking a boat therein with flotation devices attached to the side support frames, flotation devices having sufficient flotation to floatingly suspend the boat lift and a boat carried entirely by the boat lift in a body of water without the aid of lake-bed supports for the boat lift or the boat and a boat lift mechanism carried by the support frames, the boat lift mechanism having U-shaped members with a first side being carried by the first side frame and with a second side carried by the second side frame with a boat lift bar located in a vertically sliding relationship in a first portion of the U-shaped members proximate the first side frame and a second end located in a vertically sliding relationship in another portion of the U-shaped members located proximate the second side dock. A cable-lift system mounted in the boat lift permits raising the lift bar while the ends of the lift bars are guided and restrained by guide slots in the U-shaped members so that a boat located on the lift bars can be lifted and suspended above the water by the floating boat lift.
