The SS Maui, constructed in 1916 by Union Iron Works in San Francisco, was a prominent passenger vessel and later a military transport with a notable maritime history. As the largest passenger ship built on the Pacific Coast at the time, Maui featured all-steel hull construction with a double bottom, large cargo hatches, and four cargo ports on each side, capable of handling loads up to 50 tons. Its propulsion system comprised two sets of single reduction geared Westinghouse Parsons turbines, each producing 5,000 shaft horsepower, totaling 10,000 horsepower. Propelled by oil-fired Babcock & Wilcox water-tube boilers, the turbines drove twin screws, enabling a maximum speed of approximately 16.5 knots. The turbines, which were among the first large twin-screw geared turbines built for a passenger ship, experienced early operational challenges, including gear abrasion and lubrication issues, but ultimately proved reliable and influential for future designs. The vessel's interior accommodated up to 252 first-class passengers, with a variety of staterooms, and was equipped with electric generators and refrigeration units for cargo and passenger comfort. Its maiden voyage occurred in April 1917, serving the route between San Francisco and Honolulu, where it quickly became the flagship of the Matson fleet, facilitating significant cargo and passenger traffic between the mainland and Hawaii. During World War I, Maui was requisitioned by the U.S. Navy and commissioned as USS Maui (ID-1514) in March 1918. She served as a troop transport, ferrying U.S. Army personnel and cargo to Europe, and returning wounded and troops thereafter. Notable incidents included engine failures and a tragic accident that resulted in the loss of a crew member. After the war, she continued transport missions, including bringing troops back from France, and was decommissioned in 1919, returning to commercial service. Reconverted to civilian use post-war, Maui resumed passenger and cargo service to Hawaii until the economic downturn of the Great Depression led to her being laid up in 1933. She was converted into a cargo ship in 1934 and, in December 1941, was purchased by the U.S. Army for World War II, where she was renamed USAT Maui. During the war, she operated across the Pacific, supporting American military efforts in Australia, Alaska, the Philippines, and Japan. Decommissioned in early 1946, she was eventually sold for scrap in 1948. Maui's service highlights her importance as both a pioneering Pacific passenger vessel and a vital wartime transport.
