Winch self-tailing 3 velocità per barche a vela (alluminio, dia. base 620-640 mm)
B1150ST Harken

These self-tailing winches raise and trim sails on the largest yachts. They are available in 2 or 3 speeds, and come in marine-grade aluminum, or with aluminum base, stainless drum, and aluminum top combinations to maximize durability and corrosion resistance. Load-carrying gears are 17-4PH stainless steel. Self-tailing jaws accept a wide range of line sizes.

Modern-style winches integrate the stripper support arm into the self-tailing jaw assembly for a clean, smooth look. Classic winches are traditionally styled with a one-piece stripper arm that attaches to the top of the winch, encompassing the self-tailing jaws.

Winches have power ratios of up to 100:1 and are often used with either hydraulic or electric drives. The 3-speed 1140ST features a backwind to ease the loads on the winch before the sheet is released.
