For 2008 the F17 comes with the Infusion aluminum mast. This is a considerable cost savings. Also there is a new mainsail and spin cut.

I think the F17 as a double hander with jib is an attractive option. On the F16 forum there is some discussion about a new class forming call "F104". F104 refers to the ISAF SCHRF rating for the class. I have seen pics of an FxOne with jib as a 2up that will fit into this class as well. Regarding the new F16 viper..I am wondering why they made it 275 lbs when the blade is 240. Perhaps this boat is targeted more for the F104 class than F16.. (Just speculating out loud..no daggers please)
