It is unknown when the Ruddy Rose was built, but she originally served as a Dutch merchant vessel. However, by 1751 the ship was stolen by the infamous pirate Bonnet. The theft was eventually discovered by the British Royal Navy, and the warship Monarch was sent to chase the pirates across the Caribbean Sea. In an attempt to escape, the Rose sailed into the mysterious uncharted waters of the Devil's Triangle, a place surrounded with gigantic reefs and covered in eternal darkness. During the chase the Rose was flying the black pirate flag, which turned out to be a fatal mistake. When she entered the Triangle, the Rose was attacked by the ghosts of the Spanish sailors whose ship, the Silent Mary, was destroyed decades earlier in the same waters. The undeadpirate hunters quickly slaughtered the entire pirate crew, and the Rose sank to the bottom of the sea, leaving only a few floating debris and the pirate flag on the surface.
When Henry Turner looks at the ship with a piece of mirror the pirate flag is flying from the mainmast. A few moments later when Officer Cole looks at the ship with his spyglass the flag is flying from the stern flagstaff.
Jeremy Love's concept artwork shows the Ruddy Rose as a 60-gun warship flying the pirate flag historically attributed to the notorious pirate captain Edward England. In the film and its novelization she is described as a barque.
The Dutch name of this ship would be Blozende Roos.
