Bob,
I am not at my boat so this is all from memory.
My boat came with 2ea 1/0 cables from the master switch to the starboard
battery compartment so I did not need to do what you are trying. However,
I did have to run a new 1/0 cable from the new "hot" bus I added in the
battery compartment to the alternator so I know something about getting a
big cable out of that compartment. My boat also has the shallow bilge and
bilge pan like yours.
There is a laid up "conduit" on my boat that runs inside one (actually,
two) of the athwartship "beams" between the starboard compartment where the
holding tank is and the storage compartment under the port settee. If you
look inside these compartments you should see how existing cables run and
my conduit had ample room to fit another large cable through it.
Next, you need to get up to the electrical panel where the master switch
is. Again, if you follow existing cables upward from the bottom of the
port settee compartment you will see how they kind of disappear behind the
interior fiberglass panel behind the chart table.
Opening up the electrical panel, I removed several screws that held down a
horizontal filler panel that contains several cable holes that feed wires
from behind the interior panel mentioned above to the electrical
switchgear. Once this panel is removed you can kind of see this rat's nest
of wires that head downward. I then used a fish tape (actually probably a
coat hanger wire) to fish a messenger line through the area so I could pull
wires from the settee compartment upward.
Not very elegant, but it is the only way you can get wires up there, as far
as I could see. Not that difficult, just kind of tedious. Good luck!
