Galvanic corrosion can happen in many places aboard your vessel. Many people believe that galvanic corrosion is only a problem below the waterline. We normally use bonding systems to reduce galvanic corrosion on our below water through-hulls, and we install galvanic isolators to prevent galvanic and stray current corrosion on under water metals. But the …
