Jim, I know what you mean. Before I got Poser, I was working on a 12 lb tube, a type 2 carriage, casson and limber. Even went over to Ft. Monroe and sketched the carrage. Taking offsets for CAD. I was going to do Pelham at Fredericksburg. Still sitting there with Stag Hound, I got to actually handle the the design pages for her from McKay's notebook. It was not what you would think; mostly cubic cross sectional estimates and sail surface area.
