The U-No had a complicated history in the Grimm family. After researching, I found out it was even more complicated.
Originally built from a former packet boat, the Betty Wright, it was a diesel sternwheeler with a wood hull. It was built in Parkersburg, WV by Earl Cooper in 1937 and was 72.8 x 18 x 3.1, powered by a 100 hp St. Marys engine. It was originally named the Verona. Cooper sold her to Ray Brookbank of Higgensport, OH, who sold her to Lyons River Transportation Co. in Pittsburgh. In 1942 she was sold again to W. F. Archey of Pittsburgh, who sold her to the Grimm Brothers (Clarence L. [sic] and William [sic], also of Pittsburgh, who renamed her the U-No in 1945. All of this information is from the Inland River Record of 1946. I think the Inland River Record is in error here, confusing the various Grimm brothers. First, if Clarence truly was an owner, it should be Clarence A., not Clarence L. Secondly, his brother was E. P. Grimm, nicknamed "Bill." He was not named William. However, see below.
Later Inland River Records show the boat to have a composite hull and that it was built in Pittsburgh by E. P. "Bill" Grimm and C. N. Grimm (Charles Norman, Sr., or "Chick", my grandfather). It was built and owned by my grandfather, Charles N. "Chick" Grimm, Sr. The original cabin and machinery came from the Verona, but were replaced later, according to my dad. Bill sold his share to Chick on October 10, 1947. A 225 hp Gray Marine diesel was installed in December of 1947. By 1948 E. P. "Bill" Grimm and O. C. Ball of Pittsburgh were listed as the owners. Bill owned her under his name and under the name Bill Grimm Towing until about 1956 when she was sold to J. E. Crivella of Pittsburgh. She was dismantled in 1960.
