When running lines to, say the bilge, or to a navigation light, is it best
to run two wires, one coming back to the ground on the panel, or just
ground it there not far from the use? It's a basic question, but I just
wondered if there's any difference.

On an aluminum boat run separate line for ground. Run a hot and ground to a
distribution panel. Then tap off the panel, I use a fuse panel, for the
loads. Running the ground as the boat hull, causes electrolysis and holes.
