The main sheet of a surf- or sail-board which is normally used only to raise or lower the sail is extended and its end fitted with a hook. The sheet is passed around the back of the surfer and the hook is then attached to the boom so that the sheet forms a trapeze which supports the surfer. The sheet may be enclosed in an elastic sheath to make it more comfortable. Instead of a hook the sheet may be attached to the boom by a piece of cable which passes through a hole in the end of the sheet.
