A ghost ship floats unmanned off the coast of Queensland, Australia

No, we're not talking the kind of ghostly galleon Johnny Depp might pick a fight with. Ghost ship is also a term used to describe boats found adrift with their crew mysteriously missing or dead. And there have been plenty of those. Most famous is the Mary Celeste, found floating with full cargo in the hold but no crew and no explanations in 1872. The weather was fine and the crew experienced seamen who simply... disappeared. Explanations range from a seaquake to piracy, and of course sea monsters, UFOs and haunted ships.
