Fulton met Robert R. Livingston
In France, Fulton met Robert R. Livingston, who was appointed U.S. Ambassador to France in 1801. He also had a scientifically curious mind, and the two men decided to collaborate on building a steamboat and to try operating it on the Seine. Fulton experimented with the water-resistance of various hull shapes, made drawings and models, and had a steamboat constructed. At the first trial, the boat ran perfectly, but the hull was later rebuilt and strengthened. On August 9, 1803, when this boat was driven up the River Seine, it sank. The boat was 66 feet (20.1 m) long, with an 8-foot (2.4 m) beam, and made between 3 and 4 miles per hour (4.8 and 6.4 km/h) against the current.
