Abstract

See full text

A sailboat winch used for trimming lines of alternate sails, such as a jib and a spinnaker, has a drum with upper and lower drum portions of different diameters separated by a continuous radially projecting lip. The upper drum portion has a first diameter and is used for trimming the jib at maximum power. The lower drum portion has a diameter greater than the first diameter and is used for trimming the spinnaker lines. The radial extent of the lip is sufficient to prevent a line, when wrapped on the lower drum, from slipping upwardly and becoming disengaged from the lower drum.
