Harken Performa winches combine the high-efficiency of the Radial line with the sandblasted grip of Harken carbon-fiber racing winches for powerful hybrids. Optimized to handle the high-strength line used on sportboats and performance cruisers, Performa winches are a great solution for crew who don’t wish to invest in carbon winches or who need racing winches in smaller sizes. Winches come in self-tailing, plain-top, or Quattro styles.

All Performa™ winches feature sandblasted drums optimized for halyard and sheeting applications using small-diameter, high-tech line. Self-tailing winches have narrow composite jaws to ensure superior holding power on small-diameter line. The self-tailing mechanism on the winch means that one crew member can quickly and easily trim or raise sails.

The Proforma winch range has sizes suitable for halyard and sheet winches on most racers and racer-cruisers.
