ABSTRACT:
A surfboard leash for attaching a surfboard to a surfer, having a tubular outer element made of a resilient material such as rubber, and a partially resilient inner reinforcement element made from a material having a limited stretching ability, such as braided nylon cord. The natural length of the inner reinforcement element is several times the natural length of the outer casing, so that when unextended it lies coiled within it, but the maximum stretched length of the inner reinforcement element is less than the maximum stretched length of the outer tubular casing so that the outer casing is protected from breakage.
