I was wondering if there is such a concept of a DC ring circuit. I know this is done in AC. I have a canbus project around a boat which involves running power in 12V DC around the boat and taking spurs off it for each node. I was thinking of cable sizing as the loads are not evenly distributed. If I run one positive cable clockwise and another anticlockwise around the boat I was wondering if I could just join them and thus balance the 12V rail.
The below is a crude illustration with a couple of loads drawn in
