Abstract
Abstract The invention is a leash which attaches to a surfboard at one end and to the surfer's ankle by means of a novel Velcro sandwich-type strap structure at the other end, the leash comprising two separable sections one of which includes an elongated length of elastic tubing through which passes a length of cord which is fixed at the ends of the tubing and is coiled somewhat inside the cord such that the elastic will stretch to a certain extent until it is stopped by the cord, the other section of the leash comprising a stronger section of tubing having no cord inside to provide a resilient buffer when the slack is taken up in the line within the first tubing.
