A variant spelling of Contoocook, a river and village in New Hampshire
Contocook (AT-36) was launched 12 January 1920 by Staten Island Shipbuilding Co., Port Richmond, N.Y.; and commissioned 20 August 1920, Lieutenant (junior grade) T. A. Patterson in command.
Contocook cleared New York 10 November 1920 for duty with the service forces in the Atlantic. Serving the fleet along the Atlantic coast and in the Caribbean, she towed floating equipment, escorted submarines, towed target rafts, brought disabled ships into port, and carried ammunition, stores, light freight, and passengers between east coast shipyards and to the fleet.
Ordered to the Pacific Contocook arrived at San Pedro, Calif., 17 August 1932 and served on the west coast until 31 August 1933 when she entered Mare Island Navy Yard and was placed in rotating reserve status. She was decommissioned there 27 November 1933 and sold 8 February 1934.
