G'day all, I'm very new to sailboarding and am having trouble rigging my sail. The problem is that the sail twists when I put it in the luff pocket, which i can't seem to avoid, which ends up twisting the boom cut out .The battens also stay on one side of the mast when i tack/gybe. Any help would be greatly appreciated. The mast and sail should match as I bought them from a windsurfing shop.
