The SS Christopher Columbus was a notable American excursion liner operated on the Great Lakes from 1893 to 1933. She was uniquely the only whaleback ship constructed specifically for passenger service, exemplifying innovative maritime design by Alexander McDougall. Built between 1892 and 1893 at Superior, Wisconsin, by the American Steel Barge Company, the vessel measured an impressive 362 feet (110 meters) in length, making her the longest whaleback ever built and reportedly the largest vessel on the Great Lakes at her launch. Constructed with a distinctive hull featuring rounded tops and lacking traditional vertical sides, the Columbus exemplified McDougall’s revolutionary design aimed at improving seaworthiness in heavy seas. Her hull was reinforced with nine bulkheads, and her propulsion system consisted of two reciprocating triple-expansion steam engines powered by six steel tubular return Scotch boilers, driving a single four-bladed propeller 14 feet in diameter. Her superstructure was mounted on turret-like hull turrets, with two decks accessible via superstructure decks on these turrets. The ship's elegant interior featured oak paneling, velvet carpets, etched glass windows, leather furniture, and marble, along with amenities such as shops, restaurants, fountains, and a large aquarium, emphasizing her role as an opulent passenger vessel. Launched on December 3, 1892, she was swiftly completed, with a contract promising rapid construction and quick passenger loading and unloading—capable of embarking 5,000 passengers in five minutes. She was commissioned in May 1893 and initially served as a ferry to the World's Columbian Exposition, carrying between 1.7 and 2 million passengers during the event, and was celebrated as the "Queen of the Lakes." Throughout her career, the Columbus operated various routes, including excursions and daily service between Chicago and Milwaukee. She was known for her high passenger capacity, reportedly carrying up to 7,000 passengers on her maiden voyage, and her extensive service helped establish her as one of the most photographed and celebrated vessels on the Great Lakes. Despite her success, she experienced several accidents, including a notable 1917 collision that resulted in significant fatalities, and she was among the first ships fitted with onboard radio by 1909. Decommissioned in 1933 amid the Great Depression, the SS Christopher Columbus was scrapped in 1936. Her legacy endures as a symbol of innovative Great Lakes passenger transportation and the only passenger whaleback ever built, with her design and history marking an important chapter in maritime history.
