Hull anodes

Bolted and welded sacrificial anodes for hulls

Deepwater’s aluminum and zinc hull anodes can be cast to suit any type of hull conditions

Deepwater's aluminum (Al) and zinc (Zn) sacrificial hull anodes can be manufactured in a wide variety of configurations, either to be welded or bolted on. All "standard" configurations are shown below. In addition to these, Deepwater can cast anodes to any size or chemical composition specifications required. Please contact us for advice on optimizing an anode to suit your specific requirements.
