Winches > Wide-Body Self-Tailing
Wide body self-tailing winches are used to trim and raise sails on the largest yachts. They are generally used with pedestal, electric, or hydraulic drives. The large diameter drums provide extra surface area for holding extremely high loads and also offer high-speed retrieval of line when sheeting.The B1140 is available with a backwind feature that allows the winch drum to turn in a counterclockwise direction to ease loads on the winch before the sheet is released.
The B980ST is offered as either a two- or three-speed winch. The B1110ST and the B1120ST are three-speed winches. The B1140ST is a three-speed winch with backwind designed for use on megayachts.
Snubbing Winch
Snubbing winches are used on very large boats to reduce the dynamic loads on winches and to hold halyards after sails are raised.
