Nacra built two models the I-17 (N17) & I-17R (F17) both were rename in 2005. Never heard of a F17R? The N17 has been replaced in Europe with the F17 model. I heard rumors that a special upgrade package is being offered to N17 owners. a history of the F17 is located at
F17 Class I-17, F17, and F17R are not the same boats. And apparently there really isn't a formula 17 class. Nacra just uses it as a sales pitch.
Being a class member & also receiving a lot of the F17 Class news in the Great lakes, I have never heard any mention of the Formula 17 Class. But if enough FX-1 ones wanted to come out in play?
