A speedboat is a mode of aquatic transportation used in Republic City. Powered by gasoline, it can travel at very high speeds across water. For this reason, speedboats have become a common getaway vehicle for pursued criminals.
After he accidentally revealed his identity as a waterbender, Amon fled Republic City via speedboat with his brother, Tarrlok. Together, the two planned to start their life all over again, and Amon remarked that there was nothing they could not do. However, Tarrlok decided to detonate the boat's gas tank with an electrified glove, destroying the boat and ending their lives in the subsequent explosion.
The boat Amon and Tarrlok used in their getaway was golden in color. In the front was the engine, while the back held all the passengers as well as the gasoline tank. The engine was internal, but the exhaust was external. Between the engine and passenger seats were four panes of glass. The seats were situated near the right side of the boat. Near the driver's seat were the control buttons and steering wheel, both of which were crucial in maneuvering the boat and keeping track of fuel consumption. There were also seats to the left of and behind the driver's seat. Near the seats were shelves, where Amon kept several electrified gloves. The floor of the small vessel was large enough to hold the aforementioned shelves of electrified gloves and even an electric backpack generator. Four people could be comfortably seated in the craft. Overall, the boat was intricately designed with ornate patterns.
