On my boat I have two large bags that fill the spaces. The bags sit on hooks, so that they can be removed. There is room under the bags for items I don't use often, like extra fenders, the emergency tiller, etc. I plan to fit boxes into this bottom space to help keep things better organized. I keep lines in one bag, and life jackets in the other. I've thought of adding a board to fit inside the lip of the line bag. I could put hooks, or cleats, on that board. That way many of the lines could be hanging into the bag. This would help keep them organized and easier to get. One thing I like about the bags is that it insures that (hopefully!!) nothing jams into the stearing quatrant or cables.
