Rosinco was a diesel-powered luxury yacht that sank in Lake Michigan off the coast of Kenosha, Wisconsin in 1928. The yacht was built in 1916 as Georgiana III and served during World War I as USS Georgiana III, a Section patrol craft, under a free lease to the Navy by her owner and commanding officer. After the war the yacht was sold and renamed Whitemarsh in 1918. In 1925, after sale to Robert Hosmer Morse of Fairbanks-Morse, the yacht became Rosinco. She was sunk following a collision in 1928 and the wreck was added to the National Register of Historic Places in 2001.^[3]
