Harken's two-speed systems are offered in configurations for boats with main sails as large as 240 ft².
• For fast sheeting in light air or during maneuvers like jibes and mark roundings, pull both tails of the mainsheet
• When more power is required, pull one tail and the purchase is doubled
• The Harken 401 Fiddle Block is meant to be used as the base of the system. Use Harken 400 Cross Block for the top.
