USS Anacapa (AG-49) was a Q-ship in the United States Navy. She was named for Anacapa, an island near the coast of California.


The ship was built in 1919 at Wilmington, Delaware. She was operated by a number of different owners under a number of different names including Castle Town (1919), Lumbertown (1936) and Coos Bay (1942).[1] Before acquisition by the Navy, she was being operated as a lumber ship by the Coos Bay Lumber Co. She was acquired by the Navy and converted for naval service as a Q-ship and placed in commission as Anacapa (AG-49) on 31 August 1942, Lt. Comdr. A.M. Wright in command. Anacapa was converted as project "Love William" under which she would appear to be a merchant vessel while actually carrying concealed weapons to attack enemy submarines.

The ship was manned by Navy personnel, but all carried merchant marine papers and dressed like merchant seamen.[2] Anacapa cruised off the west coast of the US acting as a decoy to attract enemy submarine attack. Like other Q-ships, she carried empty oil drums and large logs both to simulate cargo and to provide additional flotation if torpedoed. Anacapa was not successful in engaging any Japanese submarines. However, she rescued survivors of the torpedoed tanker Larry Doheney near Mendocino, California in October, 1943. It is also believed that she damaged two friendly submarines with depth charges when they were improperly operating in her vicinity.

Late in 1943 she was relieved of Q-ship duty and served out the rest of the war as an armed transport, based first at Pearl Harbor and later at Anchorage. Her ports of call included Tarawa, Saipan, Guam, Ulithi, Truk, Nukufetau, Adak, Attu, and Dutch Harbor.

The ship was originally built with a relatively shallow draft and flat bottom to allow her to navigate far upstream in the rivers of Oregon and Washington in order to load lumber and logs. This made for a rough ride in the open ocean, but it also proved quite valuable in the island-hopping campaign in the South Pacific as Anacapa's shallow draft allowed her to deliver cargo to islands without improved ports. She was often the first ship in to re-supply Marines on Pacific islands as soon as major combat had ceased.

Anacapa returned to San Francisco in March, 1946, was decommissioned, transferred to the Maritime Commission, and saw further service as a merchant ship. Initially, she was given back her old name of Coos Bay (1946), but was later renamed George Olson in 1947. She was wrecked and sunk under that name while hauling lumber in the Columbia River on 30 January 1964, although the wreck is sometimes confused with the wreck of the George L. Olson, a wood-hulled lumber vessel that sunk in the Columbia River in 1944.[3][4]
