Wouter,
Um, I'm sorry, but isn't this thread about "US" youth cat sailing? We need to build with what we have, which, whether you like it or not, is Hobie 16s and Waves.
Our time is much better spent building and promoting the programs, rather than designing, building and trying to sell new boats.
I don't know how many times this needs to be pointed out to you, but kids are sailing BATHTUBS (Optis) in ridiculous numbers because of the PROGRAMS.
