An inflatable floating boat lift device constructed of a flexible impermeable fa bric comprising main air chambers and a network of hoses and valves connected to a blower contro lling the inflation and deflation of each main chamber independently. This device provides vertical lifting and stability of the boat while floating at the surface of the water. There are smaller adjustable buoyancy devices inside the main air chambers that provide floatation of the dev ice when the main chambers are deflated. These buoyancy devices also guide the boat onto the lifting device. On some embodiments, a level sensing device activates blowout plugs that rapidly return the boat to it's original floating position.
