Notes: In 1907, John F. Craig moved from Toledo, Ohio, where he and his father had just sold their family shipyard to Long Beach, Cal., where he established a new Craig Shipbuilding Co. On 1 January 1916 he sold this yard to a new organization, the California Shipbuilding Co., along with its contracts for two submarines and a lighthouse tender (Yard nos. 121-123). In the spring of 1917 Craig realized that the market for steel cargo vessels was exceedingly favorable and secured a piece of land directly adjoining the plant of the California Shipbuilding Co. That firm soon began experiencing difficulties so Craig bought it back and began operating both yards together. In August 1917 the Craig Shipbuilding Co. was reported to be building two small steamers for Swayne & Hoyt, which became Eldorado and Silverado (Yard nos. 124-125, see Design 1097). It was also then understood that the yard would build two steamers for the USSB. On 20 August 1917 the California Shipbuilding Co. received a contract from the EFC for three Design 1021 6000 dwt cargo ships (EFC 423-425, Yard nos. 127-129). In December 1917 Craig formed the Long Beach Shipbuilding Co. which took over both the new Craig Shipbuilding Co. and the California Shipbuilding Co. In July 1918 the Long Beach Shipbuilding Co. received its first contract for 8800 dwt ships (Design 1019), leaving its three Design 1021 ships (Ozaukee, Oshkosh, and Magunkook) as the only ones of that type built. The EFC did not consider it a standard design and it was not credited to its naval architect, Theodore E. Ferris. A distinctive feature of these Long Beach yards was that they side launched their ships into a narrow harbor channel.
