I haven't watched the movie for a while. However I recall that the "Pearl" was a real ship as opposed to a computer generated one. If that is true then there is a real ship out there that portrayed the pearl and someone should know who she is. Maybe I'll check google.

:Of most importance to the film were the three ships: the Black Pearl, the Dauntless and the Interceptor. For budget reasons, the ships were built on docks, with only six days spent in the open sea for the battle between the Black Pearl and the Interceptor.[12] The Dauntless and the Black Pearl were built on barges, with computer-generated imagery finishing the structures.[9] The Black Pearl was also built on the Spruce Goose stage, in order to control fog and lighting.[9] The Interceptor was a replica of the Lady Washington, fully repainted before going on a 40 day voyage beginning December 2, 2002, arriving on location on January 12, 2003.[13] A miniature was also built for the storm sequence.[9]

[edit] Armament
The Black Pearl is heavily armed, she carries 32 6-pound cannons: 18 on the gun deck and 14 on the upper deck. Its full broadside contains 16 cannonballs and weighs 96 Ibs. (35,8 kg). Strangely, the Pearl does not have any guns neither on the bow nor on the stern which is very unusual for a pirate ship and gives her a grave tactical disadvantage during a chase; the Pearl isn't able to shoot the ship she chases or to reply her hunter's fire. Only her high speed negates this handicap partially. In Dead Man's Chest another advantage the Black Pearl has over her enemies is her ability to hide in the sea at night, if all the ship's lamps are blown out then the ship is no longer visible on the sea thanks to her black hull and sails. This is also seen in Curse of the Black Pearl where she is able to sneak into Port Royal under the cover of darkness, unhindered.
[edit] Filming
In the first movie, the Black Pearl was a steel barge with wooden structures built on top to resemble a real ship. In addition, a soundstage set was used to achieve better control over fog machines. For the second and third movies, a floating sailing ship was actually built in the shipyards at Bayou La Batre in Alabama on the hull of ship Sunset to serve as the set, though it is not an authentic tall ship.[1]
