History
She was laid down at the Seattle shipyard of the Lake Union Dry Dock and Machine Works, one of 203 "Six-Bitters" ordered by the United States Coast Guard. She was designed for long-range picket and patrol duty during Prohibition for postings 20 to 30 miles from shore. The date of her launching and completion is uncertain although the class design was finalized in April 1924 and all of the Six-Bitters were commissioned by 1925. She was commissioned in 1925 as CG-263. On 21 February 1934, she was transferred to the United States Navy and designated as a Yard Patrol Craft (YP). She was assigned to the 13th Naval District where she trained reservists. She was struck from the Naval List on 25 November 1938.
