Based on the info below, it appears that the first steamboat in regular service on the Great Lakes stopped in Sodus Point on its maiden voyage on April 25, 1817 commanded by Captain Malaby.
Sources disagree as to which was the first steamboat on the Great Lakes. Some say it was the Canadian built Frontenac (170 feet), launched on September 7, 1816, at Ernestown, Ontario (about 18 miles from Kingston). Others say it was the U.S. built Ontario (110 feet), launched in the spring of 1817 at Sacketts Harbor, New York. It appears that while the Frontenac was launched first, the Ontario began active service first. The Ontario began its regular service in April, 1817, and the Frontenac made its first trip to the head of the lake on June 5.
