The ultimate clew tie down system for the Laser®. One end of the strap has velcro on both sides. It then sandwiches between the hook velcro, providing so much contact area that the strap will not slip. The webbing is 25mm wide. A piece of hard, boom friendly, material is sewn in and reduces friction between the webbing and the boom. The strap is easy to attach, but it won't loosen and it will still slide nicely along the boom.
