Galvanic currents are something that EVERY boat that's plugged into an electric hook up are liable to. It's NOT something that affects some boats but not others, and it is NOT caused by is faulty electrics, bad steel etc.
Just like toast always landing butter side down, it’s a fact of life. Or more accurately, a fact of physics – an electro-chemical reaction between a boat and it’s surroundings.
ALL metal hulled vessels that plug into shore power need Galvanic isolation to prevent hull rot, and fortunately, it’s easy and cheap to protect your boat.
Our Galvanic isolators just plug into the boat’s hook up cable, and you’re protected. Simple as that.
