<p>A reefing or furling boom (10) comprises a boom (11) connected to the mast (14) by a gooseneck (16), and a roller (12) onto which a sail (13) may be wound connected to the mast by a universal joint (15). The free ends of the boom and roller are interconnected so as to swivel together. The foot (6) of the mast end of the sail is connected to the universal joint such that the mast end of the sail can be wound onto the roller without substantial deviation from the line of the mast.</p> |
