I seem to remember that in the F16 class we have :

- 1 modified A-cat (now full spec F16) ; it was a prototype boyer mk 5 that the new owner could buy cheap

- several (modified) mosquito F16 in South Africa and Australia. Quite fast and quite inexpensive.

- a modified nacra 5.0 (now full spec F16) in California

- Dave Parker looking to add a spinaker to his Mystere 5.0 and thus make it into an inexpensive full complient F16

Certainly to full blood F16's will be faster but it surprises me how fast these modificated boats still are.
