The Adam E. Cornelius, built in 1959 in Manitowoc, Wisconsin, is a former lake freighter notable for its transformation from a powered vessel to an unpowered barge. Originally constructed as a lake freighter, she was the third vessel to bear the name Adam E. Cornelius, honoring one of the co-founders of the American Steamship Company. Her construction in 1959 marked her as a mid-20th-century cargo vessel designed for Great Lakes shipping. Throughout her service life, the vessel underwent several significant changes. In 1973, she was sold to Keybulk Transportation, leading to her being renamed and eventually converted into a barge. This conversion involved removing her original engines and cutting a large notch into her stern, enabling her to be used as an unpowered barge towed or pushed by tugboats. She was renamed Sea Barge One following her conversion. Her new configuration allowed her to be coupled with tugs using two different systems over the years. Initially, she was pushed by the tug Atlantic Hickory. Later, in 1999, her stern notch was modified to accommodate the Bark River Articulated Tug Barge Coupling System, which involved large pins on the tug Jane Ann IV that mated with sockets in her stern notch, facilitating more efficient and flexible towing operations. Her service as a barge extended into the late 20th and early 21st centuries, with her being listed for scrap in 2005, marking the end of her operational life. Her history reflects the adaptability of Great Lakes shipping vessels and illustrates the common practice of converting powered freighters into barges to extend their service life. The vessel’s various name changes—Adam E. Cornelius, Sea Barge One, Captain Edward V. Smith, and Sarah Spencer—highlight her extensive operational history and the ongoing evolution of maritime cargo handling on the Great Lakes.
