USS Seatag (SP-505), 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 (SP-505) 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.

Notes

^ The Dictionary of American Naval Fighting Ships at http://www.history.navy.mil/danfs/s8/seatag.htm and NavSource Online at http://www.navsource.org/archives/12/170505.htm give Seatag's speed as 22 miles per hour, implying statute miles per hour, an unusual unit of measure for the speed of a watercraft. It is possible that her speed actually was 22 knots. If 22 statute miles per hour is accurate, the equivalent in knots is 19.
