Correct but the FX1 fleet in truth had already began to sell their boats and buy F16's prior to the event.
A well sailed FX1 is just about on a par with a F16 but it would seem that we are getting faster as we sail and understand the boats more, where as the FX1's are not. I see no reason why the FX1 shouldn't really compete in the F16 class as perhaps a grandfathered boat, even though they technically are not class legal.
