Daisy Chain of Electrolysis
The instance of electrolysis is prevalent in marina and yacht club environments with increased connectivity to shore power.
A common earthing conductor connects all vessels together.
The dissimilar metals on the vessels are electrically connected through the individual connections to shore power outlets with all vessels sharing a common electrolyte, namely water.
A circuit or loop is created between vessels with whichever vessel having the 'least noble' metal fittings or equipment underwater suffering the highest instance of corrosion.
