When I first starting asking around here about the FXone Wouter said that the USPN for this boat is B.S. After sailing the boat I know this to be true.
There are more things people simply don't believe when I say them but then find out its true years later !
One would think that after a while people would start to recognize a trend.
Anyway, to the other statements of your post.
H20's are the first stage on proving the speed of a spinnaker cat design. These boats are not particulary fast nor particulary slow. I have no double that the spinnaker on the 1-up FX-one will make that boat faster around the course. The A's, F18's and F20's (I-20's) are the next steps up however and harder to beat.
Also in the picture it appears you are running with a lot of mast rake. I used to start that way on the FX-one I sailed extensively. That is till the owner allowed me to retune the rig. I found that the mast could be placed on the boat relatively straight. It will tack alot better as it will come out of one alot more easily and you get some more power. The only drawback is that in a big blow the bows will tip in a little easier but I still I found the boat to sail nicer and perform better with the mast raked as any modern racing cat, i.e. just aft of the vertical. You may want to try this. Don't listen to much to the feel of your rudders as the FX-one rudder etup I sailed with was well balanced and hid any excesssive weather helm really well.
