Commissioned at Boston

Halcyon II, a 161-ton steam yacht, was built by Charles Seabury Gas Engine & Power Co. of Morris Heights, Bronx, New York in 1907, and was purchased by the Navy in August 1917 from her owner, D. W. Flint of Providence, Rhode Island. She commissioned 15 December 1917 at Boston Navy Yard.

World War I service

After fitting out, Halcyon II was employed as a section and harbor patrol boat in Boston Harbor through the rest of World War I and into the first year of peace. She performed this service until 4 June 1919 when she was rammed and seriously damaged by the steamer Bayou Teohe.

Decommissioning and disposal

Determined by the Navy to be unserviceable, she was struck from the Navy List 31 July 1919 and sold her back to her former owner on 4 December 1919.
