A hull ( 10 ) for an aquatic vessel which provides a shark-repelling region about the vessel. The hull ( 10 ) includes two electrodes connected to an electromagnetic field signal generator, which in use, generates an electromagnetic field ( 40 ) about the vessel which repels sharks. The electrodes may be formed from the ends of an electrode cord ( 23 ), or may be formed from conductive ( 24, 25 ) plates ( 20, 21 ) mounted to, or integral with, the hull ( 10 ). |
