Thanks for your reply Bill,

I think we are comparing apples to oranges by trying to get the same sail area to righting moment ratio between a 10' wide, 251 sq ft Tornado and a nut busting 8.5' wide boat with Carl's 300 sq ft worth of sails. I'm not trying to defend Carl's desire for monster sail area but I am trying to defend the addition of racks to the 6.0NA to achieve considerable more righting moment with minimal weight gain. OK, my 6.0 is a good deal heavier than the Tornado and even with Racks, I'm not claiming it will be just as fast, but with my current upwind sail area (which is actually greater), I can achieve the same sail area to righting moment (same 320lbs of crew weight; although this is pretty light for a 6.0) ratio double trapped on a 2.5' rack. Add Carl's monster sail area and yeah, our boat + racks would have to be 18.9' wide.
