I guess the carbon could have been used make more of those overly heavy Nacra 20 masts and then sold at enourmous expensive to anyone unfortunate enough the break one. Another waste of Carbon?

I don't see it as a waste to try something different (a carbon fox), or to try and get out throught the surf even though you may not make it. A carbon fox protoype would be cheap compared to developing the moulds for a new 20ft hull design.
