Stow everything, including sails not set. You may not move water, dead weight or ballast to alter trim or stability; floorboards, bulkheads, doors, stairs and tanks stay in place and cabin fittings stay on board. Bailing is fine. Class rules may change this (canting keels and water ballast are allowed by many).
