  • Patent number: 5194026
    Abstract: This disclosure is directed to a surf board leash device and method that prevents the leash (line) between the surfer's ankle to the surf board from getting tangled up with the surfer's feet. This surf board leash device and method uses a clip on device containing "VELCRO" members as part of a belt clip to allow the leash line to break away from the surfer's waist during a fall or "wipe out" from the surfer's ankle, when the surfer starts to fall off the surf board. In addition, the surfer will be able to surf longer with a higher degree of safety because of not worrying about the surf board leash getting caught between their feet. Thus, the surfer's attention and concentration will be directed at making the ride on the surf board last as long as possible. Furthermore, this new surf board leash device will not cause any damage to the surfer's swimsuit as the leash will breakaway from the swimsuit belt clip when the surfer falls.
