At the cessation of hostilities YF-446 was assigned to the 16th Fleet in Texas for decommissioning and storage. On 17 July 1947, YF-446 was stricken from the Naval Register and transferred to the Coast Guard. She was then converted for use as a buoy tender and entered commissioned service on 5 September 1947. She was assigned to the 9th Coast Guard District and was based out of Detroit, Michigan.
