I flew an F-18 chute on my Nacra Uni. The Uni is wider, taller, no heavier, and carries more sail area than the Inter 17. The F-18 kite is bigger than the Inter 17's, and like another poster said, can be had for extremely affordable prices. I don't remember what I paid for mine, but it couldn't have been more than a couple hundred dollars back in 2000. For singlehanding, I never felt like I was lacking power upwind - if it was light, I eased the sail and outpointed everyone, and if it was heavy, I trapped and went fast. Good luck with a great boat.
