The greatest natural threat to the structural integrity of a marine vessel’s hull is corrosion, but a well-selected anode is a powerful ally against this threat. To help combat the corrosive effects on the vessel’s hull, zinc and aluminum marine anodes are commonly used. Zinc anodes have a long history of use in the industry, but are most suitable for saltwater, while aluminum is suitable for salt, fresh, and brackish water. The type of vessel and which component needs protection (such as hull, rudder and heat exchangers) will also play a role in the selection of the type of anode, as well as its format.
