The Sonny-S was built in 1948 by the Nolan boatyards in Erie, Pennsylvania.

Originally built as a gillnet fishing vessel she plied the Ohio waters of

Lake Erie for many years fishing mostly for yellow perch until the State

of Ohio banned gillnetting on Ohio waters. She was then converted to a

passenger vessel and was operated by Sonny-S Boat Line, Inc. until 2010.

She is currently being leased to Island Service Company, who is currently

operating her as Middle Bass Ferry.
