My water tank is centered forward of the fish hold, I know this because I had to remove it to repair a cracked weld in the tank. My battery charger is starboard but it is not very heavy. Currently aft most of my weight is on the port side IE: batteries, small anchor with chain, lots of line, etc, starboard there is another small anchor, fillet table light BBQ, etc. The starboard side has the typical stuff plus a porcelin marine head and holding tank in the fish hold. I keep looking for something obvious but the weight seems to be equally devided.
