After you furl some of the sail in move the sheet leads forward to improve sail shape. It's a very good idea to practice this in a moderate breeze instead of waiting for panic time. Mark the track or rail, if using snatch blocks, where their forward position will be. For optimal sail shape you would like the head sail to break evenly when you head into the wind( the sail should luff from top to bottom at the same time)
You wont get great sail shape with it furled but it's better than standing on your ear.
