PROBLEM TO BE SOLVED: To provide a low-frequency current type ship bottom anti-fouling system capable of effectively preventing attachment of attached organisms such as crustacean such as barnacle and shellfish, and seaweeds to a ship bottom by using the low-frequency current. SOLUTION: A plurality of electrodes are arranged underwater on an outboard shell, and the supply current is converted into the low-frequency current. The low-frequency current is conducted between the electrodes with water around the ship periphery as a conductor to realize the attachment preventive effect of attached organisms. In particular, the current is conducted simultaneously, cyclically or at random from one selected anodic electrode to a plurality of cathodic electrodes, and the direction and the intensity of the low-frequency current underwater are controlled to enhance the attachment preventive effect.
