Doug,
Because A cat hulls are typically canted outward at the bottom, the tops are inboards about 2" from max beam. Since you trap out from the top of the hulls, many A cat designs add these little flanges so that you are trapping from the max beam.

I agree the Balance A is high.


why dont you buy and XJ and a Blade from Vectorworks, they'd probably give you a discount if you bought two boats at once. It would be easier in terms of delivery too.
