The USS Ellen (SP-284) was a United States Navy patrol vessel that served during World War I, with her exact specifications and service details subject to some historical uncertainty. Originally built as a civilian motorboat, Ellen’s construction date is variably recorded as either 1911 or 1915, with construction taking place in Staten Island, New York, or Greenport, New York on Long Island. The vessel’s physical characteristics are not detailed in the available sources, and there is ambiguity regarding her size, design, and propulsion. The Navy acquired Ellen around May 1917, either on or before the 10th or 14th of that month, for wartime patrol duties. She served in the 3rd Naval District, primarily conducting section patrols in the New York City area. Her operational role was to monitor and secure the waters around the busy port during the wartime period, contributing to the broader U.S. naval effort to safeguard maritime traffic and coastlines. Regarding her service status, sources differ: some indicate she was placed in service on 10 May 1917 in a non-commissioned status, while others suggest she was officially commissioned on 10 August 1917. Her service ended either on 31 May 1918, when she was returned to her owner, or she remained in service through the end of World War I, being sold postwar on 30 April 1919. The limited and conflicting details reflect the challenges of historical record-keeping for smaller auxiliary vessels of the era. It is important to distinguish USS Ellen (SP-284) from USS Ellen (SP-1209), another patrol vessel in commission during the same period. Overall, USS Ellen (SP-284) represents a modest but integral component of the U.S. Navy’s coastal patrol efforts during World War I, exemplifying the use of civilian vessels for wartime maritime security.
