I know my younger daughter will sail the F12 the only question is the bouyancy for a crew because we have a very social junior sailing here now and its not uncommon for 2 boats to stay on the beach and have 4 or 5 in a boat all laughing and carrying on. My 8yo lad will sail the F12 when he's big enough but at the moment he's about right on the Arafura in light wind and we've just had a 12yo join the club who will be sailing my other Arafura. I have a policy at the club of rigging all cats then let the kids sail what they want, they actively change crews and once the F12 is on the beach I don't think it will stay dry.
The early F16 was based on the established 4.9 Taipan's and similar which I believe are superb boats, my approach to the F12 is not commercial its just kids on cats which will be slow but sure.
Wouter at my club the F12 project is already a great success, when it started I had two 420's for kids and that was our total junior sailing now I have had 20 different kids sail our 5 cats this summer without a sexy F12 sitting on the beach so just sip on your beer and think positive thoughts.
