This kit includes everything you need to install the 6:1 cunningham that cleats on the mast. This is a popular rigging configuration for camps or daysailing when you want to keep hardward out of the cockpit and off of the deck. It is not the most ideal for racing in that in order to ease or tighten the cunningham the crew would have to move inboard. For racing configurations see the links below. The kit includes the line (3/16″ Excel Pro), the stainless steel snap hook, Harken micro single with becket, Harken micro cheek, clam cleat, and fasteners.
