rust at waterline on narrowboat - propeller pittedWhen your boat’s connected to an electric hook up, smaii unwanted electrical currents flow in the earth conductor, and these currents make the metalwork of your boat rot away MUCH more quickly than it should.

That’s why anodes don’t last long, prop’s get pitted, and you see rust along the water line of your boat.

It doesn’t have to be like that! Our Galvanic Isolators just plug into your hook up cable, and BLOCK the currents that cause the rot. It’s a simple and efficient solution, and you can fit it yourself in a few seconds. You don’t even need a screwdriver!
