I think that having a 2up class for the FXone is good idea like the F16's have. It looks like Hobie Cat Europe wants it to go this way as well. The FXone handles weight really well. The jib kit comes with a second set of trap lines. Its a bit heavier than than the F16's at 325 lbs with a jib and spinnaker, but its a foot longer as well. It's slightly lighter than a Inter 17 and the Inter has a bigger sail to make up for it.
