I don't know much about putting on an outrigger, but I've heard of the compass thing and my Father in Law did that on his ocean going kayak, it really is a nice feature. I also knew a guy who built (or bought) a little rack that went just behind him to put some extra cargo. Nothing big that would cause you to tip easy, but he would put a couple bottles of gatorade on it and some food for easy access. However, being behind him, it took some flexibility to reach what he wanted. All in all, it was a decent addition, but I don't think I would do it.
