Running Backstays

A Wire Stay with a Block  and Tackle: A popular running-backstay solution is a wire stay attached to a block and tackle with a 4-to-1 purchase and a cam cleat. This system, while affordable and relatively simple, only generates approximately 300 pounds of torque. While this is enough for backup support of the mast, it won’t be very useful in actually shaping the mast for high performance unless it’s aggressively sweated. Also, the multiple purchases create considerable friction and can be somewhat cranky when you’re trying to ease the tackle forward for stowing.
