Franck -
As a non-"pro" I can tell you I have recently purchased my first F18. It is a 2007 Nacra Infusion. I plan on possibly buying another F18 next season. Undecided on the model.
Thanks to you I am actually thinking about not bothering with this class at all.
Perhaps it is no more than a language barrier - but NO ONE here is impressed with your rants. You are, as we say in my language, "digging a hole".
Cheers,
Karl Funk
Karl stop being a drama queen!

Go sail your boat!
