The USS Marie (SP-100) was an armed motorboat built in 1912 by Seabury’s at Morris Heights, New York. Originally a civilian vessel, she was acquired by the U.S. Navy on 28 April 1917 from her owner, O. M. Pynchon, in response to the needs of World War I. The Navy formally took delivery of her on 1 May 1917 and commissioned her as USS Marie (SP-100) on 15 June 1917. Constructed as a motorboat, the USS Marie was repurposed for naval service as a section patrol vessel. Her primary role was to conduct patrol duties along the U.S. coastline during the war, helping to safeguard waters against enemy threats and enforce maritime security. During her service, she operated within the section patrol, performing routine patrols for the duration of World War I. Measuring approximately five years of active service, the USS Marie was part of a small group of vessels bearing the same name in the Navy, with another USS Marie (SP-1260) also in commission during this period. Her service concluded shortly after the war ended; she was stricken from the Navy List on 6 August 1919. Subsequently, she was sold on 2 October 1919 to E. J. Steiner. Although specific details about her dimensions, armament, and operational highlights are not provided in the source, her role as an armed patrol vessel underscores her contribution to the maritime defense efforts of the United States during World War I. Her transition from a civilian motorboat to a naval patrol craft exemplifies the adaptability of civilian vessels in wartime and highlights her part in the broader scope of naval operations during that era.
