When your boat's plugged in to an electric hook-up, it's at risk from Galvanic Corrosion. Galvanic corrosion sounds scary - and it is, but the problem isn't hard to solve.... Simply fit a Galvanic Isolator. And the great news is that you can do it yourself - in seconds.
The majority of metal hull and sterngear corrosion is caused by Galvanic Currents, which can shorten the life of your boat's anodes, hull etc. - dramatically! Outdrives and saildrives are especially vulnerable, as they are usually made from "soft" metal alloys, and are easily corroded.
Whenever your boat's plugged into a shore supply, (electric hook up), you absolutely need a Galvanic isolator - EVEN if you have nothing switched on. People often tell me, "I hardly use any electric - it's just a back up for my solar", or, "I only use electric to charge my batteries". But it doesn't matter how much - or how little - electric you use. If your boat's connected to a hook up, you 100% need a Galvanic Isolator!
A Galvanic Isolator can completely STOP Galvanic Currents from flowing, and when the Galvanic Currents stop, the corrosion they cause simply can't happen. Result: Longer lasting anodes and no underwater damage from Galvanic corrosion.
Fitting our Galvanic Isolator takes a few seconds. Anyone can do it - you don't need an electrician (or even a screwdriver). The protection starts the very second you plug it in. Full Lifetime Guarantee. Made right here in the UK.
