A hand-operated winch designed for marine craft and in particular for use as a sailboat sheet winch is disclosed. All braking and bearing elements are sealed and not exposed to the elements. It includes silent one way clutches as opposed to conventional pawl escapements for braking. Several different winch diameters may be produced using a common working mechanism since the drum is separable from the working mechanism. Dual thrust rings allow axial loads to be sustained.
