The Flying Dutchman is a legend about a ghost ship. It was supposed to be a Dutch man-of-war at first, and indeed SOME account, and by no means the oldest ones, describes it as a pirate ship. But most account just describes it as a ghost ship of Dutch origin that sends messages to dead people. https://en.wikipedia.org/wiki/Flying_Dutchman A simple Wikipedia search is enough, it got plenty of reference too. Maybe Google it next time. BTW, I read some time ago that one explanation for "ghost ships" were ships carrying wooden logs that were abandoned by their crew for whatever reasons. The logs would help the ship to keep its buoyancy even as they suffered damage underwater, so those ships would be floating and moving for a long time even without a crew manning it.
