Ohio-a diesel yacht built in 1922 at Newport News, Virginia, by the Newport News Shipbuilding and Dry Dock Company-was laid down on 1 August 1922; launched on 16 September 1922; and delivered exactly two months later to Edward Willis Scripps, the publisher of the Scripps-Howard Newspapers.

[1] On 21 August 1940, as America girded for World War II, the United States Navy purchased Entropy from Robert V. G. Furman of Schenectady, New York, classified her a submarine chaser, and designated her PC-459.

Since American submarine chasers were unnamed during World War II, the ship was known simply by her hull number, PC-459.

[1] Upon arrival at San Juan, Puerto Rico on 1 February 1941, PC-459 was reclassified a patrol yacht, designated PY-18, and named Turquoise.

On 1 August, when the Navy commissioned the Naval Operating Base at Trinidad, British West Indies, the patrol yacht received orders to report there for duty as temporary station ship.
