Still Crazy came with a cooler rack. We immediately removed it because of the obnoxious penetration into the cockpit area. Rather, we keep two smaller coolers on the floor and use them for additional seating. Ours is a factory supplied rack that very easily removes with just two spring loaded pins.
Also, I'm very interested in filling the splash well notch to keep following seas at bay, and that would interfere with keeping the cooler rack. I'm also trying to keep as much unnecessary weight from being located far to the rear of the boat. So, I'd not sell my rack or the big ol' cooler, but it will probably just sit in the garage during the time I have the boat.
