The Zhouboat is a boat in Grand Theft Auto: Chinatown Wars. It is seen in the mission Torpedo Run. You are required to destroy it with torpedoes from the Destroyer boat that you have to get at the dock at the beginning of the mission. When you have destroyed it, you then have to go to a dock and continue the rest of the mission. When you get to the dock, there will be another boat docked there which is in fact the same boat you had destroyed earlier, the Zhouboat.
