hello,
you can't really compare the tornado with production 20' boats. the stifness of the tornados these days is the main difference. they used make tornados more flexible in the beggining. $2600 for a brand new boat imported from England. H14 was $1195 by comparison. the stiffness/low weight thing is the main reason tornados cost so much more than say an I20, and the main reason they are faster.
all the other stuff people wrote is true too.
As for carbon, the shortage is already here. Our suppliers told us no new carbon for 3 years. the military gets it all. that basalt fiber should be getting real popular. if anyone has a replenishable source for carbon i'd sure like to find out where it is.
