Ranger was built as the civilian steam-driven, steel-hulled yacht Thomas Slocum in 1910 by the Robert Jacob Shipyard at City Island in the Bronx, New York. She later was renamed Ranger. From 1917 to 1919, she served in the United States Navy as patrol vessel USS Ranger (SP-237), being renamed USS SP-237 in 1918. SP-237 was transferred to the Department of Commerce for use by the Coast and Geodetic Survey on 28 April 1919. Named USC&GS Ranger in Coast and Geodetic Survey service, she operated along the United States East Coast and in the Atlantic Ocean during her entire career with the Survey. On 28 June 1922, Ranger joined the Coast and Geodetic Survey launch USC&GS Marindin in searching for survivors of the schooner Rose Standish, which had burned off Morro Point Light, Puerto Rico, although none were found.
