The SS Manoa was an American freight and passenger steamship operated by the Matson Line, serving the route between San Francisco and Hawaii from her launch in 1913 until her decommissioning in the late 1960s. Built by Newport News Shipbuilding and launched on November 1, 1913, she was designed with a distinctive aft-engine and funnel configuration, a feature that set her apart from contemporaries by reducing passenger vibrations and soot deposition on deck. Her maiden voyage concluded with her arrival in Honolulu on March 24, 1914. The vessel's design included a bridge deck housing officers' quarters, a promenade deck with ten deluxe cabins, and the main deck with twenty additional passenger cabins, accommodating approximately 90 passengers and a crew of seven. Her passenger accommodations varied in price, with private cabins on the promenade deck costing between $350 and $500 in 1920, and more economical options available on the main and promenade decks. Throughout her service, Manoa primarily transported passengers and cargo on a weekly schedule from San Francisco to Honolulu and Maui, serving this route until 1942. She played a notable role in the 1926 Dole Air Derby as a navigational marker. Following the Attack on Pearl Harbor in 1941, the Manoa was repurposed for military use, along with other Matson ships, under the U.S. Maritime Commission. In 1943, she was transferred to the Soviet Union under the Lend-Lease agreement, renamed Balkhash, and used for various wartime purposes, including transporting Estonian prisoners to the Gulag during World War II. She was modernized in Chinese shipyards in 1956, returning to service as a cargo-passenger vessel. The ship was transferred to the Far Eastern Shipping Company in 1964 and was decommissioned in 1966. Subsequently, she served as a floating repair base for navigation systems in Vladivostok until her hull was reportedly scrapped in 1975, although some sources suggest her hull may have remained in use until 1985 or later. Her long service life underscores her significance in early 20th-century maritime history, especially in Pacific passenger travel and wartime logistics.
