ABSTRACT:
A self-tailing winch for use on a sailboat comprising a rotatable drum and a clamping pulley attached to and axially aligned with the upper end of the drum. The pulley has a rigid upper jaw and a flexible lower jaw formed from elastomeric material. There is a recess under the material of the lower jaw to permit it to flex into the recess and at least partially close it so as to afford an additional degree of flexibility to the lower jaw.
