Sort of related to this thread........
Was the Stealth almost a decade ahead of its time? Looking at the most 'recent developments in hull design' AKA Narcra F20 Carbon and DNA 'A'Class you could be forgiven for thinking that you were looking at photographs of a Stealth hull. All of them are very flat from the CB case to the transome. I can't upload photo's from the DNA blog so you can find them yourselves;

So perhaps with a slightly different sail plan you could have the "cheapest" uber F16 off the peg with ALOT of carbon as standard.
This photo is of the F20 and not to be mistaken for a stealth's transome.
