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?
Nope.....
Inter 17R (Longer Carbon mast), 17 sqm kite (I think) - NOT in the EU (I asked and Nacra quoted silly money to import one into the UK).
Inter 17 EU - Alu mast with 17 sqm kite (in mainland EU I think) and 19sqm in the UK
Inter 17XL - Same mast as the I17EU but longer boom and so larger mainsail (again UK 19sqm, EU 17sqm I think)
F17 - Essentially the same as the I17R except (I think) 2 kites, 17 and 19 (or maybe 21) sqm based on the helms weight.
