Carbon winches are standard in many racing classes and are also the choice of performance-oriented fast cruisers.
Winches feature carbon skirts and tops, aluminum drums, and strong composite jaws with one-piece sculpted line guide and peeler. PEEK® roller bearings are low-maintenance, reliable, and efficient. They ride in large-diameter cages, allowing more bearings to carry the load. Stainless steel drive gears are strong and durable.

Carbon winches come with up to three speeds and can be driven by handle, pedestal, or by electric or hydraulic motors. Options include self-tailing, top cleats, free-spinning or ratcheting base sheave additions, and left-handed rotation.

If class rules dictate, winches are also available in all-aluminum with stainless steel gears.
