The PO installed the house batteries in the bottom of the cabinet in the "stateroom," or portside quarterberth, depending on your definition.The starter battery is on the original position waaaay down in the starboard locker, which has had a floor added. All three are close to the egine and all electical controls, so no long wiring runs.Frankly, I don't like the solution because of the lost storage space and difficulty reaching the starter battery, but haven't had time to tackle a change.I like the bilge solution best: centers the weight down low.Sanders
