A zinc anode cathodic protection system comprised of six 60-lb anodes suspended around the hull periphery performed adequately for approximately 18 months in a sea water environment. Operational maintenance was required for removal of the anodes during relocation of the drydock and for periodic measurement of the hull potential. If a galvanic anode system is preferred to an impressed current system on the basis of simplicity, cost and maintenance, zinc is recommended.
