George M. Verity is a historic towboat now displayed as a museum ship in Keokuk, Iowa.

Built in 1927 as SS Thorpe, she is nationally significant for being one of only three surviving steam-powered towboats in existence in the United States.

Its internal structure involves a then-experimental truss system to support the weight of heavy components, including the boilers and engines.

[3] Verity was built in 1927 at Dubuque, Iowa for the Inland Waterways Corporation, an arm of the United States Government, as SS Thorpe, as one of four towboats that inaugurated barge service on the upper Mississippi River.

The museum opened in 1962, with the boat installed in a permanent drydock facility.
