We had an aluminum
arch made with two legs on each hull
(inboard of steps on the sloping flat area). The arch has an pole on the port side where we mounted radar
scanner and wind gen above the radar
. I replaced the single engine
with two golf cart batteries (just fit in the box) so I wired the negative directly to the batteries and the positive through a stop switch mounted below the sink in the aft (port) cabin
. From the stop switch, positive lead goes through a 50AMP fuse and then to the batteries. I ordered an ammeter to monitor output, but I don't have it yet.
bank setup is not conventional due to refrigeration
system. I'm currently installing an Adler Barber clone (12 V DC) system after removing the engine
driven system (broken). The DC fridge requires heavy cables
which I didn't want to run from the starboard hull
or to the main breaker panels
. I installed an extra 8 breaker panel on port side of bridge deck
for the fridge and other new equipment
. The two golf carts on the port hull are paralleled to the 4 golf carts on the starboard hull to make one large house bank and no engine start battery. I know I'm defying conventional wisdom here, but it really simplifies everything. I can isolate the port batteries from stbd batteries if I suspect a problem in one bank. I may eventually install and "e-meter" on the port side so I have a better idea of amps going in or out of that side.
This is a long answer to your question, but thought you would be interested in how we are setting up our boat.
