Zinc anodes are recommended for sailing on salt water or brackish water.
For sailing on salt water or brackish water, we recommend the use of zinc anodes. Cathodic protection by means of anodes is a ”must” for the protection of all metal parts under water. Therefore, not only for steel boats, but also for wooden, fibreglass and aluminium hulls, anodes are required. The material of VETUS zinc anodes is of the highest possible standard, the U.S. mil.-A-18001 K. specifications. Anodes which do not meet these specifications have little or no effect at all.
All VETUS anodes are streamlined and mounted either with specially made studs, which can be welded to a steel hull, or special through-hull bolts for fibreglass and wooden boats. We supply these studs and bolts separately.
When ordering, please always specify the material of the hull. All metal parts must have a direct contact with the anode. Therefore the bolts supplied for e.g. fibreglass hulls must have a wire-connection, so that contact can be made with the metal parts. On fibreglass and wooden boats only the metal parts must be protected.
The anodes are supplied excluding connection kit. For anode type 25 two connection kits are needed. All VETUS anodes have a protective layer of paint at the mounting side to prevent damage to the paint work of your boat.
