There is no F16 sailor.

Just as there is no F18, F20, Tornado, or Hobie 16 sailor.
I know lots of F18/Tornado/whatever sailors that only sail for fun at their club and maybe sail a few regattas a year, there are also those who go to every regatta.

You just cant label F16 sailors as not "hardcore" racers, just as you cant label they as funcruisers.
Everyone is different and might have his own goals etc.
