As soon as you have capsized try to get onto the centreboard as quickly as you can to stop the boat inverting. Grab the righting line and lean back, as you go into the water pull the windward wing down so that it is on the surface. Still in the water position yourself so you are about half way along the wing, reach in and grab the mainsheet, this lifts you partially out of the water and gets the boat moving forward. Climb in to the boat grabbing the tiller on the way and off you go.
