Suzanne, I am not sure which is the most recent. The initial mailing I got a few years ago showed all four but Hatteras was the most prominently shown. I simply asked them to send me all four and sent a check for the total amount rather than waiting several months between them and paying in monthly installments. I am sure that if you were to purchase the Barnegat one that they will send you info on the rest or if you call them, you can probably get info on all of them before you purchase anything.
