SS Christopher Columbus

The SS Christopher Columbus was an American excursion liner on the Great Lakes, in service between 1893 and 1933. She was the only whaleback ship ever built for passenger service. The ship was designed by Alexander McDougall, the developer and promoter of the whaleback design.

Columbus was built between 1892 and 1893 at Superior, Wisconsin, by the American Steel Barge Company. Initially, she ferried passengers to and from the World's Columbian Exposition. Later, she provided general transportation and excursion services to various ports around the lakes.

At 362 feet (110 m), the ship was the longest whaleback ever built, and reportedly also the largest vessel on the Great Lakes when she was launched. Columbus is said to have carried more passengers during her career than any other vessel on the Great Lakes. After a career lasting four decades, she was retired during the Great Depression and scrapped in 1936 by the Manitowoc Shipbuilding Company at Manitowoc, Wisconsin.

The history of the Columbus is linked with that of the whalebacks, an innovative but not widely accepted ship design of the late 1880s, and of their designer, Alexander McDougall. A Scottish immigrant, Great Lakes captain, inventor and entrepreneur, McDougall developed the idea of the whaleback as a way to improve the ability of barges to follow a towing vessel in heavy seas. Whalebacks were characterized by distinctive hull shapes with rounded tops, lacking conventional vertical sides. Waves thus broke across their hulls with considerably less force than when striking a conventional hull. Water could also flow around the rounded turrets which resembled gun turrets on contemporary warships; the superstructure and deckhouses were mounted on these turrets. The rounded contours of whalebacks gave them an unconventional appearance, and McDougall's ship and barge designs were received with considerable skepticism, resistance, and derision. As they had porcine-looking snouts for bows, some observers called them "pig boats".

After McDougall was unable to persuade existing shipbuilders to try his designs, he founded the American Steel Barge Company in Superior, Wisconsin in 1888, and built them himself. McDougall actively promoted his design and company by sending the SS Charles W. Wetmore to London, and starting another shipyard in Everett, Washington, which built the SS City of Everett. When the 1893 World's Columbian Exposition, to be held in Chicago, Illinois, was in the planning stages, McDougall recognized another opportunity to publicize his design. The Columbus, conceived as an elaborate ferry, was intended to demonstrate that the whaleback design would work well in passenger service, and would be able to travel at high speed. The ship's name honored the explorer Christopher Columbus as did the World's Columbian Exposition itself, timed to coincide with the 400th anniversary of his first voyage to the New World.

The World's Fair Steamship Company ordered the construction of the Columbus at an estimated cost of US$360,000. The job was undertaken at McDougall's American Steel Barge Company works in Superior, Wisconsin, starting in the fall of 1892.

The hull framing, which included nine bulkheads, was completed on September 13, 1892. The ship's propulsion mechanisms were next installed, consisting of a single four-bladed, 14-foot (4 m) diameter, 19-foot (6 m) pitch propeller, the two reciprocating triple-expansion steam engines (with three cylinders of 26-inch (66 cm), 42-inch (107 cm) and 70-inch (178 cm) diameters in a common frame with a 42-inch (107 cm) stroke) manufactured by Samuel F. Hodge & Co. of Detroit, Michigan, and six steel tubular return Scotch boilers, (11-foot (3 m) diameter by 12-foot (4 m) long), built by Cleveland Shipbuilding Company. The rounded hull top was then added, followed by the six turrets, which were substantially larger than those employed on freighter whalebacks. The ship was launched on December 3, 1892, after which two superstructure decks were mounted on the turrets along the centerline of her hull to afford access to her two internal decks, one in the turrets and one in the hull below.

She was fitted out over the remainder of late 1892 and early 1893. Electric lighting was used, and she was elegantly furnished. Her grand saloon and skylighted promenade deck contained several fountains and a large aquarium filled with trout and other fish of the lakes. The cabins and public spaces were fitted out with oak paneling, velvet carpets, etched glass windows, leather furniture and marble. Shops and restaurants were provided for the passengers.
