Interesting comments on navigation of the Constitution.
When you say "[Preble] was about 200 miles off..." was that mainly in latitude or longitude? If he was determining latitude by noon sights but longitude only by DR, I'd expect the error to be mainly in longitude.

I wish there were more details on period navigation :( Enjoy !Thanks for posting this. Some interesting interviews that I had not seen before. The hype regarding the 'secret weapon' USS Constitution was just a bit over the top at times.The movie had just one navigation related scene, when the midshipmen were gathered on the quarterdeck for a lesson. They were using an assortment of sextants and octants appropriate to their ratings and social class.Regarding the Constitution and navigation, the first Atlantic crossing by Captain Preble in 1803 was accomplished by noon latitude sights and dead reckoning. He was about 200 miles off in his reckoning when he arrived off Spain.During the War of 1812, both Hull and Bainbridge seem to have relied on similar methods, although Bainbridge was provide with a chronometer which went unused. The next Captain, Charles Stewart, also had a chronometer and used it to determine longitude beginning in 1814.Don Seltzer
