I think it's much the same as with any other brokered boat, except that the price ranges tend to be tighter. The fact that there are so many boats of the same model, of the same age, with the same outfitting, with about the same use, all for sale
in the same location creates more consistency in terms of both asking and selling prices.
This of course may vary a bit from model to model and depending on location.
I have a boat coming out of the program in just under a year. When I asked the broker what my model boats were actually selling for his reply was upper 60s. I've seen them listed for 70-75.
