Aero 9

The thread from Cirrus detailing the evolution of rig on his development single hander recently suggested that the benefit of an "oversize" rig is marginal in terms of speed across the wind range and to some degree narrows the usable wind range.

Weight carrying is more a function of hull form than sail area IMO, adult sailors mostly fall in the  65-105 kg weight range but that's a large variance and a hull that works well for a 65kg lightweight is never going to work well for a 105kg big guy, and vice versa. To me the Aero looks like a lightweights boat so the big sail can't sufficiently compensate for the extra 40kg of displacement much in the same way that a Phantom is going to be an unwieldy beast for a 65kg sailor even if carrying a much smaller sail than the standard rig.  

The Aero hull is too light for it to carry a large person. The weight of the sailor is too big a proportion of the whole package. Overpowering it isnt going to help.

From the few I've seen, the 9s look really hard work above a 3
