Don't know what the '12 is like, but in my 07 I relocated the battery boxes as far forward as possible. It gave me about 3-4" extra room. The amps are mounted on the back side of the bulkhead, and on the back of the front seat, above the batteries. My ACR is on the front side of the bulkhead, and that leaves plenty of room for everyone's boat bags/backpacks/purses. My cooler sits behind the driver's seat. Carry three ski's under starboard seats, one of which is my Connelly V with double sidewinder bindings. In the starboard locker bottom up I have; 400lb bag, buoys, surf board, deflated tube, and most commonly used life jackets. Room to spare in there for other "necessities". In port locker I just have my 1000 lb bag. I had 8 people and all our junk out last week with no floor space taken for stuff except the cooler.
