Galvanic Corrosion, (and how to stop it).
If your boat’s plugged into an electric hookup, to prevent Galvanic Corrosion, you should fit a Galvanic Isolator.
They work by blocking the unwanted “Galvanic” currents that cause corrosion. When the Galvanic currents stop, so does the corrosion. It’s as easy as that.
Typical signs of Galvanic Corrosion are pitting around the waterline, and anodes that don’t last as long as they should.
With the price of anodes getting more expensive by the month, it pays to protect them. Our Galvanic isolators don’t just protect your hull, but your anodes too. The Galvanic isolator just plugs into the electrical cable, so no actual installation is needed. No tools are required, and you don’t need any electrical knowledge whatsoever.
Your Anodes should NOT be eaten away quickly!
Although it’s true that your anodes protect your boat’s metalwork by “sacrificing” themselves, they should still last a reasonable length of time. Don’t assume that corroded anodes are “Doing their Job”. Rapid anode use is a sign of problems – usually Galvanic corrosion, which typically erodes the anodes first, then other parts of the boat. Most boats don’t have nearly enough anodes, and if areas of your boat aren’t properly “covered” by anodes, they will be vulnerable to Galvanic corrosion.
