PURPOSE:To provide a corrosion preventive electrode device of an ocean sailing body capable of decreasing sailing resistance and improving propulsion performance by decreasing the projecting area of the corrosion preventive electrode of the ocean sailing body from outside plating. CONSTITUTION:A stowage box 3 is embedded in the inner side of the outside plating 1 of the ocean sailing body and the outer side thereof is opened. A spring 4 for ejection is arranged in the bottom of this storage box 3 and a corrosion preventive electrode plate 2 consisting of Zn, Al, etc., is placed via an insulating sheet 6 thereon and the outside surface of this corrosion preventive electrode plate 2 is made flush with the outside plating 1. Fixing grids 7 are mounted at this outside surface. |
