The USS Nepenthe (SP-112) was originally a luxurious private yacht built in December 1916 by the Mathis Yacht Building Company in Camden, New Jersey. Designed for comfort and elegance, the vessel was classified as a "houseboat," emphasizing livability over speed or military capability. It was constructed for industrialist James Deering, who owned estates in Chicago, New York, Paris, and a prominent Florida estate at Vizcaya near Miami. The yacht’s design reflected Deering's refined tastes, featuring fine accessories, monogrammed French linens, and similar furnishings to the Vizcaya mansion, underscoring its role as a mobile extension of his luxurious lifestyle. Constructed as a vessel for leisure, Nepenthe was kept in constant readiness for use by Deering, who frequently wintered at Vizcaya from late November to mid-April, entertaining notable guests such as Lillian Gish, President Warren Harding, and Thomas Edison. The yacht was also used for recreation and social cruises, including a notable Florida Keys trip with artist John Singer Sargent in 1917, during which Sargent produced watercolor sketches. In June 1917, the U.S. Navy acquired Nepenthe for wartime service during World War I, designating her USS Nepenthe (SP-112) and assigning her to the 7th Naval District for operations in Florida waters. However, her design and construction proved unsuitable for military use, and she was returned to her owner in October 1917 after only a few months of service. Following Deering’s death in 1925, Nepenthe continued to be used until it was sunk during the devastating 1926 Miami hurricane, a year after Deering’s passing aboard the SS City of Paris in 1920. The vessel was salvaged after sinking and was subsequently sold. Throughout her brief service and subsequent history, Nepenthe remains a notable example of a luxury yacht adapted for military use during wartime and a symbol of Deering’s opulent lifestyle.
