Oh ya... CB. My first two-hour session in <6kt winds, as mostly an altar boy ...taught me: 'Git rid of that F'ing SUP leash!'
I made both the waist harness and leash; I will be sticking with the waist attachment but a coil leash. I may even limit the coils as a 6-foot board is sure as hell not as long as a 10 or 12-6. I have a long walkout, so the leash spends a lot of time scheming on how to wrap the mast. Press on.
