Abstract
A backwind feature is provided on a line-receiving winch and is particularly suitable for use on high capacity sailboat winches. The winch includes a main drive train to drive the drum of the winch in a winding direction and to prevent rotation in the opposite direction. A planetary gear assembly is provided on the output shaft of the winch, which permits independent rotation of the drum by a separate worm drive, without the need to disconnect any portion of the main drive.
