The USS Margo (SP-870) was a raised deck cruiser originally constructed as a private motorboat in 1913 by the Mathis Yacht Building Company in Camden, New Jersey. Designed by John Trumpy for owner George H. McNeely of Philadelphia, the vessel featured a distinctive raised deck covering crew quarters and extending over the engine room, with a trunk cabin that included a saloon and owner's stateroom. The saloon was approximately 16 feet long, furnished with a long sofa, lockers, buffets, and Pullman berths, accessed via a stairway from the main deck. The owner's stateroom was located aft of the saloon, finished in ivory white with mahogany trim, and equipped with easy chairs and rockers, creating a luxurious interior. The vessel was powered by a single Standard six-cylinder engine rated at 195 horsepower, providing a maximum endurance of about 500 miles at 8.6 knots. It had a fuel capacity of 200 gallons and was equipped with a small electrical generator driven by the main engine. Its design included a single funnel and two masts, characteristic of early 20th-century motor yachts. In June 1917, during World War I, the U.S. Navy acquired the Margo under a free lease from McNeely, commissioning her as USS Margo (SP-870). She was assigned to the 4th Naval District and based in Philadelphia, where she conducted patrol duties in the Delaware River area throughout the war. Her service was relatively brief, ending in December 1918, when she was returned to her owner. Following her naval service, the vessel was sold and renamed Pandora III. She remained in civilian hands, owned by various individuals in the New York area until she was scrapped in 1955. The USS Margo's transition from private yacht to naval patrol vessel exemplifies the common practice of repurposing private yachts for wartime service, highlighting her maritime significance during World War I.
