A Zinc Anode for Ships is a sacrificial (galvanic) anode designed for the cathodic protection (CP) of ship hulls and submerged metallic components in seawater environments. The zinc anode protects steel structures by corroding preferentially, thereby preventing corrosion and extending the service life of the vessel
