USS Seatag

USS Seatag , also spelled Sea Tag, was a United States Navy patrol vessel in commission from 1917 to 1918.
Seatag was built in 1917 as a private motorboat of the same name by the Great Lakes Boatbuilding Corporation at Milwaukee, Wisconsin. On 9 July 1917, the U.S. Navy acquired her under a free lease from her owner, Donald Ryerson of Chicago, Illinois, for use as a section patrol vessel during World War I. She was commissioned as USS Seatag or Sea Tag on 1 August 1917.
Seatag served on the Great Lakes for the rest of World War I. She served primarily on the Detroit River and St. Clair River patrols until 4 October 1918.
Seatag was decommissioned on 18 November 1918, a week after the end of World War I. She was returned to Ryerson on 7 March 1919.
