Abstract
A solar powered boat lift includes a support structure adjacent to the boat to be lifted. There is a platform for accommodating the boat thereon and cables are operably connected to the platform for enabling raising and lowering thereof. A plurality of reversible DC motors are mounted to the support structure and operably connected to the cables for selectively driving the cables longitudinally in a first direction to raise the platform and in an opposite direction to lower the platform. A rechargeable battery is operably connected to each DC motor for providing electrical power to drive the motor. A solar collector is connected to the rechargeable batteries for collecting solar energy and converting such energy to electrical power that is delivered to the rechargeable batteries for recharging thereof. In an alternative embodiment, a single solar rechargeable battery is employed and a power cable is electrically interconnected between the motors and attached to the support structure entirely above the water.
