If you really want to point, best thing to do with the jib on a Nacra 6.0 is to install a zipper fore-and-aft and open up the zipper when you're going upwind so the jib doesn't mess up the main.

Did you ever notice how much better a sloop rig goes upwind in a breeze when the leech of the jib rips open?

Actually, I'm sort of serious.
