Smotts' Revenge

From WoWWiki

Smotts' Revenge is a ship belonging to the Hecklebury Smotts, a privateer who now runs his operations from Booty Bay. Both his first ship as well as his second, 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's loaded with cannons and ready for battle.
