    Dictionary of American Naval Fighting Ships: The first Sentinel (SP-180), a motor boat built in 1917 by Pacific Shipyards and Ways Co., Alameda, Calif., was purchased by the Navy from W. G. Tibbetts on 9 August 1917 and commissioned the same day, Ens. C. A. Lundquist USNRF, in command.

    Sentinel operated in San Francisco Bay during and after World War I, patrolling the harbor entrance and assisting small vessels. She was decommissioned on 20 March 1919, transferred to the Coast Guard on 18 September 1919 and renamed Tulare. She was again renamed AB-14 on 6 November 1923, and remained in service until 1934.
