Adam E. Cornelius (ship, 1973)

The Adam E. Cornelius, (formerly the Roger M. Kyes), is a lake freighter built in Toledo, Ohio in 1973. She was renamed, after Adam Edward Cornelius, one of the co-founders of the American Steamship Company, in June 1989, after an older ship named after him was sold. She is the fourth vessel to be named after Cornelius.

While most lake freighters are powered by four-stroke engines the Cornelius is powered by a pair of two-stroke diesel engine.

Boatnerd reported the vessel earned a reputation as a "hard luck" ship, experiencing mechanical failures, and groundings.

The vessel is equipped with a conveyor system below her holds, and a self-unloading boom.
