Flying Dutchman

The Flying Dutchman is an old ship from maritime folklore. In the series, the ship and its surrounding legends were revealed to be real.

Appearance
The Flying Dutchman is the stereotypical representation of a ghost ship: old, broken down and worn from time. There are boards missing from the hull, the sails are torn and tattered, and moss is growing out from various spots of the ship. Its size is much bigger than the Thousand Sunny, and the mast seems to be like a clock tower in design. On the bottom front sail is the name "FLYING DUTCHMAN", and the top one bears the crew's Jolly Roger, a fanged skull with cutlasses, their blades pointing down in place of crossbones. The ship's figurehead bears the same skull and swords.

History
Hundreds of years ago, the Flying Dutchman was cursed by God to wander the seas forever due to the cruel actions done by her captain. Van der Decken uses it to attack pirates going to Fishman Island and steal their treasure. Recently, the Flying Dutchman has encountered the Strawhat crew aboard Thousand Sunny.

Legend
The Flying Dutchman is described as a ship that is unable to make port, and must wander the endless oceans forever. This was due to its deranged captain committing atrocious crimes, and God's wrath punished him and cursed the ship for it. It is a bad omen when the ship does appear. The captain of the "Flying Dutchman", in both sailing lore and in the series is named Van der Decken.

Fishman Island Arc
When the Straw Hat Pirates entered the Deep Sea with their coated ship, the Thousand Sunny, they eventually met the Flying Dutchman at 7000 feet below the surface. The haunted ship with its crew attacked the Sunny in an attempt to steal the treasure on board, but were impeded by underwater volcanic activity.

Trivia

 * This so far appears to be the only ship able to travel under the sea and resist the intense pressure without any form of coating. How this is possible has yet to be revealed.
