Mike, great question. I use mostly laundry baskets also, but I have a couple of organizers. Bags on the inside of the bulkhead, a place to hold the hatch covers, and a place to hold the keel winch. I have attached some pictures. I have also made a strip of starboard, not shown, which keeps the laundry baskets from sliding to the center when the boat heels to port.
My boat is one of the early ones, #7 which has a smaller vertical hatch than later models. This makes a big step to get out of the cabin. I use a plastic milk carton as a movable step that is just the right height and can be moved in and out of the way easily.
