The movie "Master and Commander" was supposedly made from book 10, "The Far Side of the World", which Jude is about to read. As nearly as I can tell, the main thing they took from the book is the route the ships followed, which is pretty much the same. The incidents were taken from all over. But it's a good movie, especially if you like old ships, as they took great care with authenticity. Aubrey's ship is really the Rose, a working replica of an 18th century frigate, built in 1970. The interior of Acheron, the French ship Aubrey is chasing, is really the Constitution, re-generated by computer from extensive shots.
I'd better not get started on the Constitution, but I truly love that ship. She was commissioned in 1798, and is still in active (not very active) service. If you're ever in Boston, don't miss a chance to see her. You can go through her, and if you hang around after the tour, you can buttonhole one of the sailors and chat with him about her.
