Smotts' Revenge

From WoWWiki

Smotts' Revenge was a ship belonging to Captain Hecklebury Smotts, a privateer who now runs his operations from Booty Bay. Both his first ship, as well as his second ship, aptly named Smotts' Revenge, were destroyed by a trio of sea giants — Mok'rash, Gorlash, and Negolash.

Smotts' Revenge is most likely the ship on the right as it is loaded with cannons and ready for battle.
