Former Vice Admiral Monkey D. Garp's ship is a battleship-class vessel. His ship's crow nests are shaped like a dog house and the figurehead is shaped like a dog head, which has a bone in its mouth. There are many sails for this ship, with the masts shaped like bones with dog-paws. The overall vessel has a dog theme, similar to Garp's mask. One of the major front sails bears the marking HQ-03 under the marine markings.

There are conveyor belts on board the ship to supply Garp with cannonballs, which, when launched with Garp's superhuman strength, surpasses the force of a cannon. He can also hurl a gigantic ball and chain that is bigger than the Thousand Sunny, although it is unknown how the ship can transport it. A big staircase leads up to the figurehead of the ship, as it doubles as a launching platform for Garp's hand-thrown cannonball barrage, and thus the ship has no front cannons. It first appeared in Chapter 91 and Episode 68. It was once seen parked outside Dawn Island. Later, Garp used the ship on his way to Hachinosu to rescue Koby from the Blackbeard Pirates.

The ship made an appearance in One Piece Film: Z.
