You need to unsheet both the main and jib or they can trap water, adding too much weight against you. I always point the mast into the wind though some advise the mast to be at an angle to it. If it is windy (which it should be if you go over) when you stand on the lower hull, by shifting your weight the wind will turn the boat relative to the angle you want. The wind on the tramp will help right the boat.
