If everything in the boat suddenly went dead, you lost ground somehow or another. That's pretty cut and dried.
Usually the batteries are wired to the engine block, and so is all the other grounds, via bus bars and etc. Check them.
I had this problem once, while out. The Previous Owner (my dad, so I shouldn't curse him as much as I'd like to) had taken all the grounds in the boat and used ring terminals to connect them all to a bolt with a wingnut, just hanging out in space, then had another wire that went from the wingnutted bolt to the engine block. The last ring connector had come loose, and the whole boat went dead.
We've since done our absolute best to gut and rewire all the crazy ghetto-wiring dad did, to pretty good overall effect. Bus bars are the way to go.
