Of course you don't need one.......
But it's much cooler if there is one
That and being able to sail in board shorts
sweet vid!!
But why do they cut the vid before they finish their gybe? i love seeing a full carve gybe being laid down and then planning out.
You can't see the gybes because he was THAT CLOSE when the helicopter was chasing them in and had to turn around somehow (ref about 3/4 they way into the vid)
Very skilled flying and camera work
