i've been waveriding strapless a far bit this summer, on a 12'6 SUP, it feels awesome, kind of a free feeling, seriously thinking of buying a 9'8 starboard SUP next summer, in 10 knots even before kites hit the water you can go wavesailing, and the surf is still a bit glassy, the feeling is a similar carvy feel of a 9ft mal but you have a sail, you can even sail beaches that aren't possible on a traditional wave board or kite, where the wind is real dodgy or non-existent on the inside.
Velcro deck, and sail in socks.. Interesting idea!
No more falling out of the straps in mid air.. and no more adjusting the size or position of the straps - just stick your foot somewhere else..
pretty sure Laird hamilton has done this in a surf movie back in the early 90's, he used booties with one side of the velcro on the bottom and on the board he had the other side of the velcro, looked like those old full deck gorilla grip, he paddled in like a normal surfer and once he jumped up was stuck to the board, showed him doing back flips off the lip and landing back on the face again, looked mad fun..
