USS Susanne (SP-411)

USS Susanne (SP-411) was a United States Navy patrol vessel in commission from 1917 to 1919.

Susanne was built as a private motorboat of the same name in 1916 by the Matthews Boat Company at Port Clinton, Ohio.

In May 1917, the U.S. Navy acquired her from her owner, T. J. Prindiville of Chicago, Illinois, for use as a section patrol boat during World War I.

Assigned to the 9th Naval District, Susanne served on patrol duties on the Great Lakes for the remainder of World War I.

Susanne (SP-411) should not be confused with the motorboat Susanne, also constructed by the Matthews Boat Company and inspected for World War I Navy service as USS Susanne (SP-832) but never commissioned, or with the patrol vessel USS Suzanne (SP-510), which was in commission at the same time.
