The USS Harvard (SP-209) was originally a private luxury vessel named Eleanor, constructed in 1894 and notable for being the largest yacht built in the United States at that time. Designed by naval architect Charles Ridgley Hanscom and built by Bath Iron Works, Eleanor measured 240 feet overall in length, with a beam of 32 feet, and a draft of 14 feet 2 inches. Her hull was constructed of riveted steel plates, featuring eighteen watertight compartments, emphasizing her size and robustness. Powered by a single triple-expansion steam engine producing 1,000 horsepower, she could achieve speeds up to 14.5 knots and was equipped with coal-fired Scotch boilers. To support her long-range voyages, she was rigged as a three-masted barque with a sail area of over 13,000 square feet, allowing her to sail at speeds of up to 8 knots under favorable conditions. Eleanor's luxurious interior included a dining room, social hall, smoking room, galley, and multiple staterooms finished with fine hardwoods and marble, accommodating a crew of around 52 in 1897. She carried multiple tenders, including steam and naphtha launches, lifeboats, and a gig, making her well-equipped for extended voyages and social functions. Her notable service began with a circumnavigation from 1894 to 1895, under owner William A. Slater, covering over 42,000 nautical miles and visiting ports across Europe, Asia, and North America. She served various prominent owners, including Robert D. Ballantine, Oliver H. Payne, Charlotte Cardeza, and James J. Hill, who renamed her Wacouta and used her primarily for fishing and leisure in the Great Lakes. During World War I, the vessel was acquired by the U.S. Navy in 1917, renamed Harvard, and converted into a patrol vessel. She served in European waters, performing convoy escort, rescue, and inspection duties, notably rescuing survivors from torpedoed ships and supervising German U-boat surrender inspections after the armistice. Harvard was decommissioned in 1919 and returned to civilian use, eventually being sold to Greek interests and renamed Athinai. She served as a coastal passenger ship until her sinking by German aircraft in Greece in April 1941, marking the end of her maritime career.
