It has a fixed ali frame similar to Wouters F12 that holds one swing down centreplate. I'm not a fan of that metal. The Arafura and Arrow were designed by the same designer as the Mozzie and that was a mini Stingray which was a mini Tornado. I really bought up the weight to show that in my opinion the modern boat should be lighter as per the original discussion with the F12 design. Specifically a cheap cat that kids can rig themselves, light weight, practical, exciting to look at, safe easy to homebuild cat.
