Herreshoff #323 was built as a motor boat to government specifications by the Herreshoff Manufacturing Co., Bristol, R.I., in 1918. She was contracted for by J. P.

She was acquired by the Navy from Morgan 6 June 1918 and commissioned 15 June 1918 at Newport, Ens. W. A. Flagg, USNRF, in command.
Herreshoff #323 was first taken to New London, Conn., for outfitting 19 June and then assigned to 1st Naval District, Boston, Mass., for duty as section patrol boat.
