Harken Grand Prix Catamaran Mainsheet System

The Harken Grand Prix catamaran mainsheet system is designed for high-performance beach catamarans such as the Nacra 17 or F18s. It is supplied as a 12:1 system and converts easily to 10:1 or 11:1 to suit the wind conditions or the crew's preference. The blocks run on ceramic ball bearings with extremely low rolling resistance, so the crew can trim easily and precisely.
