USS YP-15 was a wooden-hulled patrol vessel in commission in the fleet of the United States Coast Guard as CG-149 from 1925 to 1933, and in the fleet of the United States Navy as YP-15 from 1933 until 1945.
She was laid down at the Benton Harbor, Michigan shipyard of the Dachel-Carter Boat Company, one of 203 "Six-Bitters" ordered by the United States Coast Guard.[1] [2] She was designed for long-range picket and patrol duty during Prohibition for postings 20 to 30 miles from shore.[3] 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.[3] She was commissioned in 1925 as CG-149.[1] On 15 November 1933, she was transferred to the United States Navy and designated as a Yard Patrol Craft (YP).[1] She was assigned to the First Naval District where she trained reservists.[1] [4] In 1942, she was assigned to Newport, Rhode Island. In April 1944, she was assigned to Portland, Maine.[1] She was struck from the Naval List on 11 October 1945 and sold to the War Shipping Administration in July 1946.[1] In 1946, she was sold to the private sector, renamed Lady Pauline (ON 250877) and thereafter had a number of owners.[1] She was scrapped in 1964.[1]
