The USS California (SP-249), originally a private yacht named Hauoli, was built in 1903 for mining magnate Francis Marion "Borax" Smith. This vessel was renowned for its speed, being perhaps the fastest single-screw yacht of its class in the world at the time. It measured approximately 179 feet 6 inches in length overall, with a beam of about 22 feet and a draft of roughly 8 feet 8 inches. Its hull featured four watertight bulkheads and a double bottom, designed for ballast or fresh water storage, with a flush deck and two deck houses—one forward and one aft—connected by a promenade deck. The yacht's interior was luxurious, including a mahogany-paneled dining saloon, private staterooms, a social room with a piano, and accommodations for crew and servants, highlighting its use for leisure and racing. Powered by four water-tube boilers driving a four-cylinder triple-expansion engine, Hauoli achieved notable speeds; during trials, it averaged 18 knots and could reach over 21 knots under forced draft, making it one of the fastest yachts of its time. Its design emphasized comfort and high performance, with electric lighting and ventilation, and a fleet of auxiliary boats, including a 20-foot electric launch. Originally used for cruising and racing in Long Island Sound, Hauoli participated in notable events such as the Lysistrata Cup race in 1904. In 1912, it was sold to Clara Baldwin Stocker, renamed California, and became the first pleasure vessel to transit the Panama Canal in 1914, reflecting its significance in maritime history. During World War I, the vessel was acquired by the U.S. Navy in 1917, re-commissioned as USS California, and later renamed Hauoli again in 1918. The Navy outfitted it with armament and used it primarily as a patrol vessel in New York Harbor, later assigning it to Thomas Edison for antisubmarine warfare experiments involving listening devices. The vessel was decommissioned in 1919 and sold in 1920. Throughout its service, Hauoli/California exemplified the intersection of luxury yachting, technological innovation, and military utility in the early 20th century.
