The ultimate clew tie down system for the Laser®. One end of the strap has the loop velcro on both sides. It then sandwiches between the hook velcro, providing so much contact area that the strap will not slip. A piece of hard material reduces friction between the webbing and the boom. Can be used with a clew hook, with or without Harken airblock, to create a quick easy and reliable clew system.
