Cathodic protection by means of anodes is a must for the protection of all metal parts under water. Not only for steel boats, but also for wooden, fiberglass and aluminium hulls, anodes are required. Vetus zinc anodes are made to the highest possible standard, the U.S. mil.-A-18001 J. specifications and have a protective layer of paint on the mounting side to prevent damage to the paint on your boat.
