SS Malolo (later known as Matsonia, Atlantic, and Queen Frederica) was an American ocean liner and cruise ship built by William Cramp & Sons, Philadelphia in 1926 for the Matson Line. She was the first of a number of ships designed by William Francis Gibbs for the line, which did much to develop tourism in the Hawaiian Islands. In 1927 Matson commissioned its largest ship yet, the Malolo (flying fish) for the first-class luxury service between San Francisco, Los Angeles, and Honolulu. The Malolo and other Matson liners advertised superb public rooms, spacious cabins, swimming pools, a gymnasium, and a staff, including a hairdresser, to provide a high standard of service.
