    Small Boat Flip-Flop blocks rotate around the line axis to keep the line close to the deck. Hinged construction allows for various lead angles and increased freedom for crews to move around. This product replaces the traditional black 10:1 holding power sheave with the titanium colored Power3 sheave. That sheave has more facets. It offers 15:1 holding power but can be bit tougher to release seamlessly in the lulls.
