That begs the question of what happens to the enormous sunk (pun not intended) costs of the current fleet and where the capital for fleet replacement would come from.

This is also an ongoing problem in farming. At some point you have to cut your losses and eat them. I put off buying a $15,000 grass seed stripper for several years. When I finally got it, it paid for itself in one year. The first ones who sell their old boats will not lose too much, since there will still be a market for their boats. The latter ones will only be worth scrap value.

I just competed a study of the Advanced Fisherman 70, which reflects a
vast amount of design energies of PB&F during the last decade.

I am convinced that it is a genius design, and if the politics were
right, a fleet of AF70's would revolutionize the modern fisheries
industry.

As a retired specialty crop farmer, I used to say it's not what you can grow but what you can sell that counts. There's a corollary for fishing: it's not your gross but your net that counts. Just yesterday I read a report of fuel prices expected to rise to $5 a gallon by 2012. A more efficient boat, producing a larger return on a smaller catch, is what I would be looking at if I were in the industry.
