ABSTRACT:
A manual swivel winch is pivotally attached to a D-ring of a barge deck, boat deck or the like. The manual swivel winch includes a pair of spaced side plates defining a substantially open bottom, a drum rotatably supported between the side plates, and a rotatable handle attached to the drum and extending from one of the side plates. A swivel link is attached to the side plates for pivotally attaching the winch to the D-ring. Each side plate may include a pair of spaced feet extending down at a lower edge thereof with a recess extending between the pair of feet. The recess combined with the open bottom provides a self-cleaning action to the manual swivel winch.
