Harken Self-Tailing Quattro Performa design combines the efficiency of Harken Radial winches with the sandblasted grip of its carbon fiber racing winch for a powerful hybrid. The patented Quattro design is an innovative all-in-one feature used on boats that require extremely fast winches to handle large asymmetrical spinnakers, but also need power to trim the genoa upwind. The Quattro features two drum diameters and four line speeds. The wide-diameter lower drum is used for fast trimming, the upper drum when more power is needed.
Performa winches transfer high loads to the winch with fewer wraps, allowing crew to trim and ease sails quickly and repeatedly as wind strength and directions change. Composite roller and thrust bearings reduce friction under load; have excellent corrosion resistance; don't require lubrication. The Snap-fit socket, washer, and screw top lift out as a unit, making reassembly mistake-free.
