The Maui HookUp is the fast, easy way to rig today's harder to downhaul sails. Developed on Maui and introduced in 1996, the Maui HookUp, with its patented cleatless system, is being used by satisfied sailors all over the world. What the Maui HookUp will do:Attach quickly and securely to your downhaul line. Give you a powerful two handed grip. Position and reposition so easily that you'll want to take more pulls in your most powerful range of motion. Give you more control when tuning. Never break or wear out. Bright yellow grips make it easy to find and hard to loose.Why are modern sails harder to downhaul?Increased downhaul effort can be attributed to the features and achievements of modern sail designs: - Loose leaches allow heads that twist off and de-power in gusts. - More tunable for increased wind range. - A well formed pocket low in the sail contour for more power and control. Higher tack force is what makes these improvements possible. Tack forces in excess of 400 pound are not uncommon in today's sails.
