It's time to tackle the electrical panel.
I just purchased a Hunter 37 cutter and I am redoing the interior. At this time I am working on the electric wiring and have a question for you experts.
Should I wire every circuit using single marine wire (of proper gauge and color) such as black for ground and diferent color for each circuit. (same as car wiring) or can I run every circuit using marine sheathed cable (of proper gauge) that has red and black in the same sheath.(similar to wiring a house, circuits are labeled)

It seems that using sheathed cable would be neeter and faster. Both ends can be labeled or numbered.

What is the norm???.

Your advise is welcomed

use the sheathed stuff, its easier to make it pretty, and if you ever need to trace it it is much easier as well.

use a nice new sharpee to write what it is every few feet and then either paint over the writing with clear nail polish, clear lacquer or clear heat shrink

You should use yellow as your DC negative/ ground wire colour. Black is used as the "hot" wire in 110VAC wiring and can be confused easily. Different colours for each circuit isn't a bad idea but you will run out of colours very quickly. Just label each circuit properly and you won't have a problem.
