Hot weather speeds up galvanic corrosion (a LOT), especially when the water is warm and your boat is sitting on its berth in a marina – and your electric hookup is to blame!
That means your hull, props, shafts and underwater fittings can disappear MUCH faster while you’re plugged into shore power, because those tiny voltage differences, known as galvanic currents, get the perfect conditions to nibble away at your metal. Your poor, hard‑working ANODES get a hard time too, wasting away much faster than they would in cooler weather.
A galvanic isolator is a neat electronic device that simply breaks that corrosive link by blocking tiny DC currents on the earth wire, while still passing AC fault current to keep you safe if anything goes wrong. A galvanic isolator is a compact (and inexpensive) unit that plugs in or wires into your shore‑power lead, and it’s genuinely easy to fit – the plug‑in types need no tools, no technical know‑how, just plug and protect, so most boat owners can do it themselves in seconds.
Once it’s fitted, you’ve greatly reduced one of the main causes of corrosion while you’re on shore power, which can save you real money in anodes, props and hull work over time. Then put your feet up with a glass of your favourite thirst‑quencher, knowing your underwater metalwork has a fighting chance in the summer heat.
