Blackbeard's Ghost Ship is (or was) the ship of Blackbeard and his crew known as The Queen Anne's Revenge. It was later used for them to build his inn on a small island somewhat connected to the mainland of Godolphin, North Carolina.
In the film
After Blackbeard performed a good deed by burning the will, thus, releasing himself from the curse, he left land; never to return or to be seen or heard from again, and joined his ghostly crew waiting for him on his ghost ship. The minute he was on board, he ordered his crew to weigh the anchor, set the sails, and hoist the colors. He was last heard laughing joyfully once the pirate flag was hoisted as he set sail to wherever the sea would take him along with his crew on his ship into a fog.
