I have designed a set of wings for my N20 but haven't fabricated them yet. They will be similar the the Aussie 18 skiff wings but not as wide and will angle up and out so there will be good clearance with the leward wing. They will be alluminum and not carbon with an open mesh. If you go this route, keep in mind the leverage that's added WITHOUT being trapped out. When you're on the wire, your body weight is adding to the mast support. Keeping this in mind, I'll be adding an tenshionable/adjustable running stay to the wing. Not sure how soon I'll be starting this project but will post pics when I do.
