Zinc anodes, also called "sacrificial anodes", protect all metal parts below the waterline from corrosion. To prevent corrosion of the hull, the anode oxidises faster than the metal it is protecting, sacrificing itself before the other metal reacts with the electrolytes. The water, which acts as an electrolyte here, varies in its aggressiveness depending on the navigable waters. Typically, anodes have to be replaced once per season. In harsh water conditions, a more frequent replacement schedule might be necessary.
