I tried to get the Paneltronics panel that you spec'd out when I first started this project, but it wasn't available. I have the Blue Seas:Blue Seas Panel
It seems to be pretty close to your setup and I get a small discount when I buy at Fisheries Supply.
In the existing wiring arrangement most of the cabling is down the sides of the hull. SInce I have easy access to the center below the sole I am really inclined to run my lines there. If the lines are off the bottom of the boat and high and dry, is there any reason to not use this avenue? I have way better access with the center of my sole removed then trying to neatly get these lines in behind the cabinets.
