The stern wheel of the Belle of Louisville turning on the Ohio River, wooden buckets set between steel arms, pitman rods reaching forward to the engine, water boiling under the fantail.
What it was used for
Built in 1914 by James Rees and Sons of Pittsburgh as the Idlewild, she worked from January 1915 as a ferry between Memphis and Hopefield Point, Arkansas. For excursion trips the Steamboat Inspection Service allowed her up to 1,600 passengers. From 1931 she carried pleasure-seekers out of Louisville to the Fontaine Ferry amusement park and to Rose Island. In the Second World War she pushed oil barges on the Mississippi and Ohio and doubled as a USO venue for troops. On 24 May 1962 Jefferson County bought her at auction for $34,000; on 14 October 1962 she was rechristened Belle of Louisville.
What was new
Nothing about her was new, and that is the point. The American Society of Mechanical Engineers describes her shallow-draft flat-bottomed hull braced by hog-chain trusses as characteristic of hundreds of steamboats on America's rivers in the 19th and 20th centuries. Her significance lies entirely in survival: she is the oldest operating western rivers steamboat, a National Historic Landmark, and since 2010 an ASME Historic Mechanical Engineering Landmark. The barb: this plain working boat, mocked as Marlow's Folly when bought, lost her first Great Steamboat Race to the Delta Queen in 1963 — and outlasted every grander rival.
