Has YOUR boat got Galvanic Corrosion? (It's easy to check).
If you use an elec' hook up, check around the boat's waterline. That's the place you will usually see Galvanic Corrosion. Look for pitting. If there is rust, scrape a little off, and if there is pitting below it, there's a good chance that it's caused by Galvanic Corrosion.
Welders LOVE Galvanic Corrosion. When boats need overplating, Galvanic corrosion is usually the cause.
Galvanic Corrosion happens when your boat is plugged into an electric hook up. It slowly but surely eats away at your boat's hull, and can easily hole it. Galvanic Corrosion is the TOP reason for boats needing overplating
So there are two choices....
You can protect your boat from Galvanic Corrosion in a few seconds with a Galvanic Isolator that simply plugs into your electric hookup cable.
You can sit back and hope for the best. A hull re-plate will cost upwards of £8k. Galvanic Isolator prices start from well under £100, so it's all a bit of a no-brainer.
