Galvanic corrosion results whenever two or more dissimilar metals (like those found on the sail-drive) are submerged in a conductive solution, such as saltwater, polluted water or water with a high mineral content because a chemical reaction takes place causing electrical current to flow between the metals.
Galvanska korozija je rezultat, kadar sta dve ali več različnih kovin (kot so na saildrive) potopljeni v prevodno raztopino, npr. morska voda, onesnažena voda ali voda z visoko vsebnostjo mineralov, ker pride do kemične reakcije, ki povzroča pretok električnega toka med kovinami.
