While you’re watching the footie, spare a thought for your boat – because galvanic corrosion certainly won’t be taking a break to watch the match. Even when you’re relaxing with a drink and cheering on your team, those tiny electrical reactions are still hard at work, quietly eating away at your metalwork.
Galvanic corrosion is relentless; it goes on 24 hours a day, 7 days a week, steadily attacking your hull, outboard, saildrive and stern gear. In fact, anything made of metal and sitting under water is at risk, whether you own a steel narrowboat, an aluminium vessel, or a GRP boat with outboard(s). The worrying thing about galvanic corrosion is that you rarely see it straight away, but over time it can turn into pitted surfaces, wasted anodes and some very unwelcome repair bills.
The good news is, it doesn’t have to be that way. Our galvanic isolators are designed so that you can install them yourself without needing any special tools or electrical qualifications. If you choose one of our plug‑in models, fitting it is basically as simple as plugging in an extension lead – you connect it in line with your shore power cable and you’re protected in just a few seconds. Once it’s in place, you can get back to enjoying the match, knowing your boat’s metalwork has a proper defence working away in the background.
You can buy our units from eBay and Amazon, or go direct to our own website if you’d rather cut out the middleman, and save some money in the process.
Ordering from us direct has the added advantage that you save a bit of money, and you also get fast, First Class shipping to UK addresses, so your isolator can be on your boat before the next big game kicks off. Either way, you’re investing in a simple, cost‑effective way to help your anodes last longer and to keep galvanic corrosion firmly on the bench where it belongs.
