I actually wrote most of that wikipedia article back in 2005 but recently someone else changed a few key comments. To my opinion these changes are just non-sense. Someone is playing with you guys here.

There is no way Hobie is going to vamp its FX-one to make it comparable to the Inter-17R and there is no way Nacra is going to downgrade the I-17R to reflect the setup of the Fx-one. These boats are very dissimilar in their rigs. The difference in mainsail area is no less then 1.5 sq. mtr. (= 16 sq.ft.)

It is all just BS.
