My friend's boat wiring is FUBAR. Its a 25 year old salt water unit
with a Cummins diesel and single screw. There is what's left of a
system to switch from Bat A to Bat B or both. Its been through a
couple 'canes and had salt water up to the deck a couple times. Plus
25 years of hack electrical repairs.

Anyway, I'd like to start with some sort of load center to handle the
winch, starter, alternator and bat A /bat B systems, and a whole bunch
of small breakers for all the small loads. Anyone know of such a unit
for salt water boats?

We have a crew of four willing to attack this problem on windy days
over the next three months. But we need her to sail when the wind goes
down.

Hello Karl.
I recently wired up a boat and used components from Blue Sea
Systems.They have an excellent tool on their website that calculates
wire sizes based on loads and
lengths and a few other factors. I actually spoke to a guy there who
knew his stuff and was very helpful (if you value that kind of stuff)

If you cant find a stock panel for your needs, you can go custom with
an outfit called Mobil Marine Wiring out of Newburyport, MA.
Disclamer: I never actually bought anthing from him, but he was kind
enough to recommend a stock Blue Seas panel for my simple setup.

As far as conductors go, the least expensive place that I found to buy
was http://gregsmarinewiresupply.com. Greg cut and put on the end
fittings for all my high current cables. For the lighter gage wires,
I bought the wire from him and crimped the ends myself. I invested a
few bucks for a double crimp tool from Ancor which made nice crimps
easily.

Good recommendations in this thread for documenting your work for the
next guy.

Good luck with your project
