Fuel tank and battery in same compartment?
My catamaran has transom-hung outboards. I'm thinking about the best location for the starting batteries and permanently installed below deck fuel tanks. We currently use portable tanks above deck. They are always tripping people, fouling sheets, or otherwise in the way. Each hull has a compartment at the stern with a bulkhead sealing it off from the rest of the boat. These compartments would be the perfect size and location for battery and tank. Assuming the battery is installed correctly (strapped down in leakproof box; vented; no ignition sources, etc) and assuming a permanent below deck tank is installed correctly (strapped down; properly installed deck fill and vent, etc), would it be illegal/unsafe/unwise to have battery and gasoline tank side-by-side in the same compartment?
