C.A. Thayer is a schooner built in 1895 near Eureka, California. The schooner is now preserved at the San Francisco Maritime National Historical Park. She is one of the last survivors of the sailing schooners in the West coast lumber trade to San Francisco from Washington, Oregon, and Northern California. She was designated a National Historic Landmark on 13 November 1966. This ship is used for many class field trips. History As a lumber schooner C.A. Thayer was built by Danish-born Hans Ditlev Bendixsen in his shipyard, located across the narrows of Humboldt Bay from the city of Eureka in Northern California. Bendixsen also built the Wawona (1897) which was dismantled in 2009. The C.A. Thayer was named for Clarence A. Thayer, a partner in the San Francisco-based E.K. Wood Lumber Company. Between 1895 and 1912, C.A. Thayer usually sailed from E.K. Wood's mill in Grays Harbor, Washington, to San Francisco. But she also carried lumber as far south as Mexico, and occasionally even ventured offshore to Hawaii and Fiji. C.A. Thayer is typical of the sort of three-masted schooners often used in the west coast lumber trade. She is in length and has a cargo capacity of . She carried about half of her load below deck, with the remaining lumber stacked high on deck. In port, her small crew of eight or nine men were also responsible for loading and unloading the ship. Unloading was an average day's work. With the increase in the use of steam power for the lumber trade, and after sustaining serious damage during a gale, C.A. Thayer was retired from the lumber trade in 1912, and converted for use in the Alaskan salmon fishery. In the Alaskan salmon fishery Early each April from 1912 to 1924, C.A. Thayer sailed from San Francisco for Western Alaska. On board she carried gillnet boats, bundles of barrel staves, tons of salt, and a crew of fishermen and cannery workers. She then spent the summer anchored at a fishery camp such as Squaw Creek or Koggiung. While there, the fishermen worked their nets and the cannery workers packed the catch on shore. C.A. Thayer returned to San Francisco each September, carrying barrels of salted salmon. Vessels in the salt-salmon trade usually laid up during the winter months, but when World War I inflated freight rates, C.A. Thayer carried Northwest fir and Mendocino redwood to Australia.
