Moby Dick

Moby Dick is Whitebeard's ship. Its name was revealed in One Piece Yellow Grand Elements.

History
Whitebeard was aboard this when Rockstar attempted to deliver Shanks's letter. Recently Shanks has met up with Whitebeard, revealing that even his massive ship is small compared to Whitebeard's. A few wooden panels were cracked by Shanks' "spirit" when he boarded the vessel.

With Ace's execution drawing near, The Moby Dick has started to sail toward Marineford by destroying all 23 battleships sent to watch over it. On the way to Marineford the Moby Dick was coated so that it could travel underwater. It later resurfaced in the plaza at Marineford.
