I must say that I was never as challenged on the FX-one design as you I-17 guys seem to tell us. Alright I had to re-rake the FX-one mast and do some tuning at first but after that I could drop the tiller just the same and do stuff on board with two hands. Several times I dropped the tiller and moved down to the leeward daggerboard to raise it and move back.

There seems to be a rumour that the FX-one and other wave-piercers will self destruct as soon as you drop the tiller while the nacra tracks like a train. I think there may be some core of truth somewhere but it is now made out to be a huge difference and that it is certainly not. Also "the cool thing about the Inter/Nacra" is not exclusive to the Inter/nacra at all; scores of V- or U-shaped keelline designs have the same behaviour. It is actually quite common. And adjustable rudder setups are found on all other designs as well.

Now I'm sure that one boat tracks better then another but I don't think we are doing the real differences any justice here.
