After all that talk about the FX-1 let us come back to the ICat.
On all pictures I know, it has only a main, but no spi. Is there one to come later? Also, it is interesting that the mast is just 8.5m, does it mean that they might offer a alu mast sometimes later?
Personally I think that the aspect ratio of the sail is too low, and without spi a downwind leg might be challenging. At all it seems not be racer.

Cheers,
