All,

After more thought I do have to admit that I do have one conduit, a PVC
pipe that protects the 12 VDC buss and several other wires passing through
four lockers in a row in the aft section.

I do have a switch panel (but no fuses) at the helm to control main engine
functions and the ship's whistle.  I plan another one at the navigators
position for other functions used by the navigator such as lights etc. But
these are the only actual panels that have a more than three switches on
them for controlling DC loads.  Most DC loads are switched on and off close
to the load.  This minimizes wiring losses, complexity and maintenance in
exchange for a little walkabout to work the switches.

I can recall the seed of that concept was years ago while visiting a boat
called Turning Point, Capt. Ron Puliot, a pre-WW2 Trumpy motorsailer.  When
he turned on the running lights by snapping switches in the deckhouse just
inside where the lights were mounted I was shocked. I never had seen
anything but the usual box of switches before.  I instantly grasped the
advantages of trading a little stroll around the saloon for the simplicity
of eliminating a pair of wires for each device on a standard switch panel. 
The ac system was more like a house with a breaker box controlling zones
and major loads and so is mine, with some unique features (of course!).
