The 1810s continued a trend of increasing commercial viability of steamboats in North America, following the early success of Robert Fulton and others in the preceding years. In 1811 the first in a continuously operating line of river steamboats left the dock at Pittsburgh to steam down the Ohio River to the Mississippi and on to New Orleans. Inventor John Stevens' boat, the "Juliana", began operation as the first steam-powered ferry October 11, 1811, with service between New York, and Hoboken, New Jersey. John Molson's PS "Accommodation" was the first steamboat on the St. Lawrence and in Canada. Unlike Fulton, Molson did not show a profit. Molson had also two paddle steamboats "Swiftsure" of 1811 and "Malsham" of 1813 with engines by B&W. The experience of these vessels, especially that they could now offer a regular service, being independent of wind and weather, helped make the new system of propulsion commercially viable, and as a result its application to the more open waters of the Great Lakes was next considered. That idea went on hiatus due to the War of 1812.
