One of the Boblo Boats, the Ste. Claire, is shown here at its new berth, where it was moved a couple of weeks ago.
The Ste. Claire Restoration Project’s History page explains:
The steamer Ste. Claire represents the typical propeller-driven excursion steamer of the turn of the century, a type once found in many parts of the country. Excursion steamers are steamships built primarily for passengers for day trips. Ste. Claire and her running mate Columbia represent the “ocean-going” type of excursion vessel although they were used on lakes.
The steamer Columbia and Ste. Claire are the last two remaining classic excursion steamers in the country; and the last essentially unaltered passenger ships designed by Frank E. Kirby; and for their essentially unaltered propulsion machinery of a type becoming increasingly rare ; as the two last vessels of the Detroit and Windsor Ferry Co.; as two of the few surviving vessels built by the Detroit Dry Dock Company, and for their unaltered propulsion machinery, which is of a rare type. Columbia is the oldest passenger steamer in the United States, excepting vessels properly classed as ferries. Columbia and her running-mate Ste. Claire are the last two steamers of their type with integrity left in the United States. The pair shared their original run from Detroit to Bob-Lo Island for 81 years, a record of service on a single run unequalled in U. S. history
