In fresh water, is there any reason an aluminum hull couldn't be used as a
chassis ground, as in vehicles back when they were made of metal? It would
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.

Don't even think about it! Your aluminum hull could look like swiss cheese
in short order. Make NO electrical connections to your hull. Run an
insulated reurn line to battery negative.
