An adaptor for replacing the crank used with a manually operated nautical winch used on sail boats. The adaptor has a body shaped to correspond to the shape of the head of the usual crank that rotates the drum of the winch. This adaptor fits into the crank head receiving socket of the nautical winch. A stem projects upward from the adaptor for connection with the chuck of a drill whereby operation of the drill rotates the drum of the nautical winch and winds the ropes of the sail onto the drum, thereby raising the sail.
