Swayne & Hoyt Lines was an American steamship company based in San Francisco, California, and in operation from the late 1890s to the late 1930s.
Swayne & Hoyt was engaged in trade with Japan by 1896, when the company was recorded as protesting duties assessed on ceramic goods it had imported in February 1896.[1]
In the years after World War I, Swayne & Hoyt was engaged in the tramp trade with leased United States Shipping Board ships but later evolved into a scheduled cargo line.[2] In 1926, the company was operating the American-Australian-Orient Line which sailed to Australia, New Zealand, and Asian ports.[3] Also in the mid 1920s, Swayne & Hoyt was engaged in trade between Pacific ports and the east coast of South America.[4]
By the late 1930s, Swayne & Hoyt was engaged in intercoastal shipping between U.S. ports on the Gulf of Mexico and on ports on the Pacific coast via the Panama Canal.[5]
