She was sold to Rich & Company. of Horicon, in 1859, who placed upper works and a cabin on her and she came out as a passenger boat under the name Shawano City. In 1863, she was sold to Abel Neff and Capt. Hank Johnson. They converted her into a growser tug, renamed her the Oshkosh, and she continued in commission towing logs until 1871.
