You do NOT want Galvanic Corrosion!

If there’s anything that can DESTROY a boat, it’s Galvanic Corrosion. It causes pits and sometimes even HOLES in the boat’s metalwork, especially around the waterline. An the problem with hull pitting is that when it’s done, it’s done – it’s impossible to repair. Sure, you can overplate, or puddle weld deep pits (if they are isolated), but in most cases, you’ll have a line of pits around the water margin, because that’s where the oxygen is concentrated.

That kind of pitting is BAD news. In most cases, it won’t actually HOLE the hull, but it makes applying hull protection difficult, which adds to the problem.

So you can see why Galvanic Corrosion is a nightmare. Galvanic corrosion is caused by electrical corrosion currents that eat away at your boat’s metalwork 24 hours a day, 7 days a week.

It’s the result of a reaction between your boat and it’s surroundings, and can be absolutely devastating, leading to overplating, and other seriously expensive repairs.

But the good news is that you can put a STOP to Galvanic corrosion once and for all with a simple Galvanic isolator, that simply plugs in to your electric supply, and completely BLOCKS Galvanic, sometimes known as  “Corrosion” currents, and it does this for LESS than £100.

You fit a Galvanic isolator by plugging it into your electric hookup cable. There’s NO wiring involved, and connecting it only takes a few seconds. The protection it gives is INSTANT. You don’t have to wait for it to “build up” or anything. Just plug in and you’re protected.

If this all sounds too good to be true, don’t worry!! Galvanic isolators are used by all the major fleet operators, on inland waterways, and on the ocean. Firms like P&O, Royal Caribbean, Costa, Fred Olsen etc. If you use a Galvanic isolator, you’re in good company!

Our Galvanic isolators are built to last. They are designed and built in the UK, and they ALL carry a LIFETIME Guarantee.
