American Sculling Championship
The American Sculling Championship for professionals are rowing races conducted under the challenge system. For details of this see World Sculling Championship, Challenges. All races were with a turn. The following table shows winners from 1859 to 1888. Other races must have taken place at a later date and others may be add to this table. Walter Brown died in March 1871 while still Champion

A much later race occurred when Tom Sullivan (rower) attempted to win the Championship of America in August 1905 when he raced Edward Durnan of Canada in a 3-mile (4.8 km) race in Toronto. Sullivan was soundly beaten and Durnan went on to unsuccessfully challenge for the World Sculling Title. Durnan was Hanlan's nephew. References
