Flying Dutchman
A ship that can never make port and is doomed to sail the oceans for eternity. There were supposed sightings in the 19th an 20th century about a ship that was glowing with an unearthly light. It is rumored that if it hailed by another ship that the crew will try to send messages to those long dead. If you see the ship at sea it an omen of doom.
