In fresh water, is there any reason an aluminum hull couldn't be used as a

alloy single conductors to be run to most devices.


Better seperate the juice from the hull, I'd think.
It only takes about a half volt to provide cathodic protection - or
just as easily, anodic corrosion. A half volt drop to an aluminum
conductor is not out of the way.
