Galvanic Corrosion Guide

This guide explains how your boat could be severely impacted by galvanic corrosion (even if moored in an inland marina) and the steps to take to mitigate damage.

Galvanic corrosion occurs when two dissimilar metals are electrically connected in the presence of an electrolyte (a conductive liquid such as seawater or freshwater). It results in irreversible damage to your boat’s underwater components - propellers, shafts, through-hull fittings etc. Anodes alone are not enough - discover more solutions in this guide.
