Looks like the move to master is the sail on head, board held by rear straps maneuver. Are you supposed to turn into wind a bit to let the board's bottom act as wing?
Is it doable when wind is super light, and all the weight of board and rig is resting on your head?
I'm gonna have to practice all this on the sand, out of the water... Better than breaking a mast or batten, I guess.
