I have been looking at 2002-2008 Hatteras motor yachts from 63-75 feet after touring a few excellent low hour boats I find it strange that the 6300 my was only made a few years then changed slightly and renamed the 6400. Seems like hatters models run for a long time especially in the Brunswick years. Is there anything wrong with the 6300 to merit much lower prices then the 64 Both boats a very heavy at 110,000 pounds. As a comparison the old Hargrave 75 was 100,000 approximately I don’t see another 60 footer in that range. Even the long running Hatteras 60 sport fish is 88,000. Could this be the reason these boats are lower prices and less desired?
