The USS Lady Anne (SP-154) was a wooden-hulled motor launch built primarily for private use before her naval service. Constructed by A. C. Brown & Sons of Tottenville, Staten Island, she was launched on July 11, 1914, following her design by Bowes & Mower. Originally named Danna, a name derived from the combined initials of her owner, Daniel G. Whitlock, and his wife Anna, she was intended for leisure cruises on the Hudson River and Long Island Sound. Danna measured 65 feet (20 meters) in length with a beam of 15 feet 3 inches (4.65 meters) and a draft of 4 feet 6 inches (1.37 meters). Her construction featured a mahogany finish in the cabins and was equipped with modern amenities such as electric lighting, nine sleeping berths, toilets, and a bath, making her one of the most complete private vessels of her kind at the time. Power was provided by a four-cylinder, 50-horsepower four-stroke gasoline engine, giving her a top speed of approximately 10 knots (19 km/h). Subsequently sold to George P. Walker of Savannah, Georgia, she was renamed Lady Anne at an unspecified date. With the outbreak of World War I, the U.S. Navy acquired her on April 10, 1917, for patrol duties. She was enrolled in the Naval Coast Defense Reserve on April 19 and commissioned on May 7, 1917, at Charleston, South Carolina. During her service in the 6th Naval District, Lady Anne functioned as a section patrol and harbor patrol vessel, primarily operating in the lower Savannah River and along the Atlantic coast, where she inspected merchant ships and monitored wireless radio communications. Decommissioned on February 8, 1919, she was transferred to the Naval Overseas Transportation Service for non-commissioned harbor patrol duties at Charleston. The vessel was offered for sale later that year, but the sale was withdrawn, and she was transferred to the Department of War on February 25, 1920. Her service exemplifies the utilization of private vessels converted for naval patrol during wartime, playing a vital role in coastal defense and maritime security during World War I.
