Heres a couple of pics of the current waist leash named the "Waister".
They have the standard Fin key grub screw system so they can be alternated to whatever sized leash you require.
I recently had a surfer paddle up to me to enquire and compliment what he called a "Man leash" which is an excellent description as it is really just an oversized ankle leash to go around your waist.
Not everyone has strong and healthy hips, knees or ankles and this leash system takes the worry out of surfing solid sized waves if you have a bit of a tweak or strain.
No more getting your legrope in-between your feet or toes, your deck is literally your 'dance floor'.
No scrawling into a ball and preparing for a leg pull on a solid day, I just position myself accordingly and wait to be assisted to the surface like the artwork in 'Beasho's" previous post on this thread.
Leash's pictured are my current 10mm 9' straight 'Waister' and an 8mm 2.1m Coil with straight section/ aka 'Monster Coil'.
The leash is still in development phase and some limited numbers are available for sale, I have some in stock and so does Balin for any retailers that may be interested.
