period in which the government was buying yachts for potential wartime use and gentlemen yachtsmen were buying suitable yachts to enroll in the Naval Coast Defense Reserve or turn yachts over to the Naval Coast Patrol on the "free rental" of $1 per month. Sybilla III was acquired 14 May 1917 under free lease from Betz and commissioned the same day as USS Sybilla III (SP-104) for service in the Section Patrol. The yacht served in the Fourth Naval District for a rental of $1 per month plus cost of restoration after use. On 24 December 1918 the yacht was returned to Betz and name struck from the Naval Vessel Register (NVR). In the 1932-33 register Sybilla III is shown with a new signal, KNMU, and diesel engines. In the 1935-36 register the vessel is shown as Arlis owned by R. Livingston Sullivan of Philadelphia. USS Impetuous (PYc-46) The Navy acquired Arlis from Sullivan for $70,000 on 12 August 1940, converted the yacht at a cost of $50,000 and commissioned the vessel USS PC-454 on 16 October with assignment to the 15th Naval District. PC-454 arrived in the Canal Zone in mid-November 1940 to patrol the approaches to the Panama Canal. From November 1940 to August 1944 she performed escort and antisubmarine patrol operations off Central America. The patrol vessel was named and reclassified Impetuous (PYc-46) on 15 July 1943. On 31 August 1944, the patrol yacht arrived in Philadelphia and was decommissioned there on 27 September, struck from the Naval Register on 14 October and sold by the War Shipping Administration on 14 June 1945.
