Racing Winch 650

Racing Winch 650

  • Self-tailing & top cleat
  • 3-speed
  • Carbon, aluminum, ceramic

Developed for the harshest conditions and most competitive races on earth, Harken carbon fiber racing winches are the choice of professionals and top tier racers alike.

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

Complete customization

Options include self-tailing arms, top cleats, free-spinning or ratcheting base sheave additions, and left-handed rotation.

Different materials

The 650 is offered with a choice of anodized aluminum drum or a high-performance ceramic coated white drum. Top and base are lightweight carbon fiber.

Self-tailing

The self-tailing mechanism on the winch means that one crew member can quickly and easily trim or raise sails.

Top cleat

Use the top cleat to quickly secure lines.
