The Harken 20STBBB size 20 self-tailing polished bronze winch belongs to the Radial Line, balancing secure grip and line longevity with smooth, controlled easing under load. Details sailors will appreciate: smaller winches that carry higher loads, stress-free seasonal maintenance, and one-person installation. The self-tailing mechanism on the winch means that one crew member can quickly and easily trim or raise sails.
