Galvanic Isolators really do make brilliant Christmas presents for boat owners. Anyone plugged into shore power should have one if they care about their hull, anodes and prop.​

Whenever a boat is connected to a mains hook up, it is sitting in a galvanic “circuit” with every other boat and bit of metal on that pontoon, and that’s when corrosion quietly chews away underwater metals. It is not just steel or aluminium hulls at risk either; GRP boats still expose outboards, saildrives and stern gear to the same galvanic currents.​

Galvanic corrosion does not clock off for Christmas; it carries on 24/7 for as long as the shore lead is plugged in, even if you are not actually drawing any current. Over a year it is quite normal to lose many kilos of metal from anodes and fittings, and a decent isolator is one of the most cost‑effective ways to slow that down.​

A plug‑in galvanic isolator is about as simple as it gets: no tools, no wiring, just plug it between the pedestal and your existing lead. If someone can manage a shore cable, they can fit one of these in seconds, which is why they make such an easy, genuinely useful gift for any boat on a mains hook up.
