I can only guess that there is a small market for 21ft "Offshore" boats that are capable of crossing over to the Bahamas. It's a big 21 and there are LOT of factors that go into people's boat buying decision. If you are shopping for that kind of boat . . . I would imagine you want and can afford something a bit larger (like 30+ ft with a real cabin to overnight in). I think more folks are interested in taking their 21ft boats to the sandbar and not paying a lot for them . . . hence the popularity of Bayliner, wellcraft, and searay. It's pretty clear to me why Potter didn't built the 21, since he was out to make a name for himself (and did with the 23 seacraft). While the ride is of interest for you and me . . . a LOT of people don't give a rats azz as long as they can put a case beer in the cooler. The fact that it hasn't been produced in it's original form, shouldn't take anything away from it's achievements . . . which you don't seem to have much respect.
