A power assist system for manually operated winches, including an electric motor (40), a motor controller (42), and a winch handle (20) with a radio module (46), enabling wireless communicating to the motor controller (42). The system is suitable for mounting onto winches (10) that has a shaft (11) accessible from the underside, typically through the deck of a sailboat. The motor (40) supplies additional turning force to the winch (10) to assist the manual operation. Sensors (31) in the winch handle measures the amount and direction of manual force and send it wirelessly to the motor controller (42) to control the motor (40). The radio signals (48) sent to the motor controller (42) has a unique address corresponding to the winch (10) it is connected to. The unique address is picked up by reading an NFC tag (13) on the winch. When the winch handle (20) is removed from the winch (10), the address is deleted, preparing the handle (20) for use on a different winch.
