The Steamboat Inspection Service was a United States agency created in 1871 to safeguard lives and property at sea. It merged with the Bureau of Navigation in 1932 to form the Bureau of Navigation and Steamboat Inspection, which in 1936 was reorganized into the Bureau of Marine Inspection and Navigation. The Bureau of Marine Inspection and Navigation′s responsibilities were transferred temporarily to the United States Coast Guard in 1942. The Bureau was abolished in 1946, when its functions were transferred permanently to the Coast Guard.
