The Harken 4 speed Plain Top winch that features a 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. The aluminum construction is designed for sailors who want lightweight, extremely strong winches with plenty of power.
