If there were absolutely no other F16's near me, I would have bought something else, what ever the popular boat was I guess, because I do not like scoring on corrected time. That is probably what is holding back growth in some areas, availability of F16 fleets to race with, but with every new boat sold, there is a new fleet building.
That's an interestijng point as I was the opposite. I bought an F16 because I wanted something light, fast and fun to sail. There are no other active F16's at my club - there is one that never goes out as far as I can see. We have one Inter 17 and 3 shadows, 2 tornados, loads of Dart 18's that never move, a handfull of Hurricane 5.9's and loads of Sprint 15's (Dart 15).
If I had wanted fleet racing I should have bought the Sprint 15. I wanted a light, high performance single hander with a Spi. Only choice was a F16.
