Protection by means of anodes is a must for all metals parts under water. Therefore anodes are required for wooden, fibre glass and aluminum hulls. The material of V-Quipment zinc anodes is of the highest possible standard, the US. mil- A-18001 K. specifications. Anodes do not meet these specifications have little or no effect.V-Quipmente aluminum anodes consist of an aluminum-indium-zinc alloy Mil- A - 24779 (SH). All V- Quipment anodes are streamlined and mounted either with studs which can be welded to a steel hull, or with through-hull bolts for fiberglass and wooden boats. We supply these studs and boats separately.For vessels, which mostly cruise on inland waters, we recommend aluminum anodes since aluminum has a greater difference of potencial with other metals than zinc. This is very important, as fresh water provides a higher electrical resistance than salt water. For sailing on salt water or brackish water, we recommend the use of zinc anodes. Aluminum anodes also function well in salt water, but are sacrificed at a much faster rate. We do not recommend the use of magnesium anodes, as the difference of potencial with other metals is too great which could cause damage to the hull paint, especially when sailing in brackish or salt waters.Our Part # VTSZINK02C | Vetus Part # ZINK02C
