The Radial White is designed for boatbuilders, designers, and sailors looking for a winch that combines bold contemporary styling with the technical excellence Harken® is known for. Winches feature mirror-finished chrome drums with white composite tops, self-tailing jaws, and skirts to provide an aesthetic option on any boat. The Radial winch drum’s gripping surface is shaped for each winch size and drum material and features diagonal ribs (rather than textured abrasive materials) to maximize gripping power and greatly reduce line wear. The self-tailing mechanism on the winch means that one crew member can quickly and easily trim or raise sails.
