The Invisible Current Eating Your Hull
Galvanic corrosion is one of the biggest hidden threats to boats, and it doesn’t just affect steel and aluminium hulls. GRP and wooden boats are at risk too, because outboards and saildrives can suffer serious damage in almost no time. For metal-hulled boats, the cost can be frightening, with repairs running to welding or even overplating once galvanic corrosion has taken hold.
That’s where a plug in galvanic isolator can make all the difference.
Fitted directly into your shore power lead, a plug in galvanic isolator helps interrupt the low-voltage electrical currents that cause galvanic corrosion in the first place. In simple terms, it helps protect underwater metals, fittings and hull components from slow, expensive damage — without complicated installation or specialist wiring – it’s a simple DIY job that takes a few SECONDS.
One of the main advantages of a plug in galvanic isolator is convenience. There’s no need for an electrician and no tools required. It’s a straightforward, practical solution for boat owners who want protection with minimal fuss.
If you’re looking for a simple way to help protect your boat from corrosion, a plug in galvanic isolator is a sound and wise investment – and it costs a LOT less than a welder!
