Anode
(15 products)
Aluminum and zinc anodes. Protection against galvanic currents using sacrificial anodes is a "must" for all metal parts underwater. Therefore, anodes are needed for wooden, fiberglass, steel, and aluminum hulls. The material in V-Quipment zinc anodes is of the highest possible standard, US mil-A-18001 K. specifications. Anodes that do not meet these specifications have little or no effect.
V-Quipment aluminum anodes consist of an aluminum-indium-zinc alloy Mil-A-24779 (SH). All V-Quipment anodes are streamlined and mounted either with stud bolts that can be welded to a steel hull or with through bolts for fiberglass and wooden boats. We supply these stud bolts for welding and through bolts separately.
For vessels mostly cruising in freshwater, we recommend aluminum anodes because aluminum has a greater potential difference compared to other metals than zinc. This is very important because freshwater provides higher resistance than saltwater. For sailing in saltwater or brackish water, we recommend using zinc anodes. Aluminum anodes also work well in saltwater but sacrifice at a much faster rate. We do not recommend using magnesium anodes because the potential difference with other metals is too great, which can cause damage to the hull paint, especially when sailing in brackish or saltwater.
