I read in the T foil thread the the F16 and F14 classes are NOT professional classes. This makes me wonder, what constitues a proffesional class?
Proffesionals sailing in the class?
Recognition by ISAF?
The class actually makes money?
The class charges for you to be "in" the class?

What in essence makes X or Y class a proffesional class?

ps: This thread is by no means, meant as a sarcastic comeback. This is a serious question and I hope this will not turn into a class vs class bickering fest.
