Check out a possible historical source of the choice of name "William Turner" in POTC. A dangerous and exciting story, and it really happened:
http://www.firstworldwar.com/features/lusitania.htmhttp://www.pbs.org/lostliners/lusitania.html"Whether or not Turner's behavior can be justified, it doomed his ship. When U-20 under the command of Kapitänleutnant Walther Schwieger found a huge four-stacker in its sights just south of Queenstown, Ireland, it was able to kill her with a single torpedo, penetrating the hull just below the waterline. The initial explosion set off a violent secondary blast. The ship sank in 18 minutes, with a lost of 1,195 of the 1,959 on board, including 123 Americans. Captain Turner was washed clear of the bridge as the ship sank, and survived after spending more than three hours in the water.
So ended the life of the Lusitania. She is now a faint ghost of the ocean greyhound she once was, one of the saddest wrecks I've ever seen. But when I visualize her upturned bow, I can imagine the pride of those who once sailed on the swiftest ship in the world."
Do you think that's who the POTC writers were thinking of?
