Sunbeam III was built as a civilian motorboat of the same name in 1917 by the Charles L. Seabury Company and the Gas Engine and Power Company at Morris Heights in the Bronx, New York. Her owner, Mr. R. B. Roosevelt of New York City, loaned her to the U.S. Navy under a free lease agreement for World War I service as a patrol vessel. She was delivered to the Navy on 16 June 1917 and commissioned as USS Sunbeam III (SP-251) on 18 July 1917.
Sunbeam III was stricken from the Navy List on 21 January 1919 and returned to Roosevelt.
- Both the Dictionary of American Naval Fighting Ships (at http://www.history.navy.mil/danfs/s20/sunbeam_iii.htm) and NavSource Online (at http://www.navsource.org/archives/12/170251.htm) give Sunbeam III's speed in "miles per hour", implying statute miles per hour, which is very unusual for a watercraft. It may be that both sources mean her speed was 14 knots; if they really do mean that her speed was 14 statute miles per hour, the equivalent in knots would be 12.2.
