Named for Medal of Honor recipient James Martinus Schoonmaker, it is currently a museum ship in Toledo, Ohio.

The steamship Col. James M. Schoonmaker began life on 1 July 1911 at the Great Lakes Engineering Works in Ecorse, Michigan.

She sailed as part of the Shenango fleet until 1969 when she was sold to the Interlake Steamship Company who chartered Col James M. Schoonmaker to the Republic Steel Corporation.

She sat as the centerpiece of the International Park in that city for several decades before being rechristened back to her original name Col. James M. Schoonmaker and being moved one last time to the site of the National Museum of the Great Lakes on the banks of the Maumee River in Toledo.

Willis B. Boyer was repainted in her Shenango Furnace fleet livery and, on 1 July 2011, rechristened back to her original name, Col. James M. Schoonmaker.
