Product Description
Harken #70 3 Speed Electric Self-Tailing Performa Winch
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.
Motors attach to central drive shaft and drive through winch gears for two-speed mechanical advantage.
