Battery Question

[Catigale]

Its almost impossible to electrically isolate a Mac from the shore mains, unless you don't have a motor. Most every install Ive seen, the motor mount goes below the water line and this case is tied to ground

[Tomfoolery]

Came across this article in Sail magazine about installing shore power. One of the better-written of such articles, with nice graphics, and not so technical as to confuse someone not familiar with AC power installations, requirements, and safe (or code-compliant, at least) practices.
