A self-tailing winch 200 for a sailboat comprises a winch drum 202 rotatable about a rotational axis and a self-tailing arrangement 220 disposed axially adjacent the winch drum. The self-tailing arrangement 220 comprises a rope guide channel 248 extending circumferentially around the self-tailing assembly, the rope guide channel 248 being defined by upper 244 and lower 246 rope guide rings, the upper and lower rope guide rings being rotatable with the drum 202 and adapted to grip rope in the rope guide channel. A feeder arm 242 guides rope between the drum and the rope guide channel, the feeder arm being fixed with respect to a support. A retainer guide 260 guides rope between the rope guide channel and an unloaded end of the rope. The drum is rotatable with respect to the retainer guide and the retainer guide is spring mounted to allow movement of the retainer guide in a direction substantially parallel to the rotational axis of the winch drum. The retainer guide has a retainer lip 266 extending partially circumferentially around the self-tailing assembly to at least partially enclose a portion of the rope guide channel 248. The retainer guide further defines at least one side of an opening 272 adjacent the retainer lip, the opening being sized to conduct rope through the opening during reverse winding of the winch, the rope thereby being retained in the rope guide channel 248 by the retainer lip 266.
