The ankle cuffs need to be 1-2 inches longer so there is enough length of velcro to insure it not coming off. Other than that, design a studded neck leash for those surfers into sado-masochism, like sigmund--he is into it, I hear say......
I've been reading aboot Elon Musk, inventor of Space-X and Tesla and other cool stuff (Solar City in LA). He doesn't accept the prevailing "wisdom" on any technical matter, he tries to reimagine it in a perfect world, and works backwards, based on sound scientific reasoning based on facts - those we are unable to disprove under any circumstance - to invent it. He may end up being the Edison of our era.
What about the same concept as the spiral leashes that are sometimes on body boards, similar to a telephone cord. The leash would basically only lengthen when there is tension on it, like in the case of a wipeout.
Lighted leaches using waterproof LED or neon rope lights for those twilight or night time surf seshes...
Nice. Of course, they will attract rather large fishes with scraggly teeth. If you don't mind that, go for it!!! See you in the ICU!!!
Barry c'mon you know I have been campaigning for leash safety and properly tied connections for some time now. If I spot someone with an improperly attached leash, I'll let them know about it. It's important. and when it comes undone in the ocean... it could be too late. do your part brah.
