I don't have a pic handy of my jib (1/2 of a Kmart shower curtain duct-taped to 3/16" nylon rope), but it hangs on a rope that runs from the bow bracket back under my left SideKick arm to the stern bracket, then up to the top of the mast, thru the sail, then back to the bow bracket. It's rather complicated - I'll post pics someday, but sounds like Stringy you have your hands full already with projects! I like your leeboard idea, and am going to try to use an old plastic meat cutting board or something to try it out on mine (using PVC pipe inside of the SideKick for strengthening).
In lieu of a jib pic, here is a pic of yours truly flying my F-16 during a nuclear flash:
