My goal would be to convert what Hatteras considered the master (the room with bunk beds). Looking at the pictures, it seems like anything wider than a twin bed would affect 1 of the doors; either the one entering the room or the door for the head. The size difference between a full and a queen is minimal, so even a full would work. After all, we're talking about a few over night trips, not our permanent bed. But I do know my wife would say no to us sharing a twin... Not enough room!There's a 36' Pacemaker by us that she is interested in. The V-berth has a bed in it (odd shaped) and the 2nd stateroom has bunk beds for the boys. Not a bad boat, twin gas engines turn me off though. I figure if I prove we can convert 1 room into something for us, she would be more excited for the Hatt.
