J. F. Duthie & Company was a small shipyard located on the east side of Harbor Island in Seattle, Washington. It was organized in 1911 and expanded to 4 slipways on 25 acres of property in World War I to build cargo ships for the United States Shipping Board (USSB). Some 24 of the 33 ships built at J. F. Duthie were the "West boats," a series of steel-hulled cargo ships built for the USSB on the West Coast of the United States as part of the World War I war effort, with 12 requisitioned and 12 built under contract.
