USC&GS Matchless was a wood, two masted schooner that served as a survey ship in the United States Coast and Geodetic Survey from 1885 to 1919. She was the only Coast and Geodetic Survey ship to bear the name and the last sailing vessel owned and operated by the Survey.
While returning from Roanoke Island to Elizabeth City, North Carolina after completion of work in Croatan and Roanoke Sounds the Matchless was caught and held in ice from about December 24, 1917 until January 17, 1918. The ship then engaged in surveys requested by the Navy in the lower Chesapeake Bay, the York River and Mattaponi River during the first half of 1918.
In her last years Matchless was used "as a house-boat" from which parties surveyed inland waters. She was surveyed and condemned in 1919, retired from Coast and Geodetic Survey service and sold June 28, 1919. The crew from the Matchless transferred to the steamer USC&GS Onward with the task of continuing the surveys in the York River and west shore of Chesapeake Bay.
