ABSTRACT:
A winch adapted to be secured to a buoy including a drum having a hollow shaft journalled at its ends, for rotation around its longitudinal axis. An elastic band is stretched through the drum and is fixed at one end to one end of the shaft and at the other end to a housing surrounding the drum. A line is wound about the drum which when played out rotates the drum about the longitudinal axis and places the elastic band under torsion, giving the drum a predetermined elastic rotatable bias.
