You got me.
I said these things in complete confidence but when you asked I could not come up with an answer. I'm usually very careful about throwing around "facts" but this one got past me. My apologies. However, everything else stands as true - find the most numerous water craft market and mass produce with in that design class with the smallest number of constituent components possible. That would decrease production costs significantly. Later, as you learn more, perhaps you can find profitable models for less common classes. I'll be honest that my interests are more about advancing our general state of technology. Be it with regards to nautical needs or anything else. The aviation industry already acknowledges that carbon fiber (and later perhaps spectra fiber) will be the future. The automotive industry is already making the same choice although only on the high end for now. Boats provide a unique opportunity to advance the field of mass composites because they posses fewer moving structural components and, generally, more continuous lines. Sure there is a lot to designing just the right shape but almost with out fail a boat's shape provides an opportunity for large singular components. I will continue to search for that $/lb reference. I'm confident I must have seen it somewhere. Thanks for catching that.
