I back out of or into a beach without touching the sails...rudders up, boards mostly up, sit forward of the main beam and the boat will back beautifully. I'm not backwinding a sail (I don't think...they're luffing). I understand the intent (and probably would never try this), but it sounds like I can still do this on a crowded start line and maintain rights as long as I don't physically move the sail over.
