Aberdeen was built by the Seattle Construction and Drydock Company in 1912 as a coastal whale catcher for the American Pacific Whaling Company operating out of Gray's Harbor from the Canada–United States border south to Cape Blanco in Oregon.[1][3] The catcher was 116 GRT and 88 feet (26.8 m) in length by 19 feet (5.8 m) beam with a depth of 11 feet 5 inches (3.5 m) and ten crew.[1][4]Aberdeen and a sister ship, Westport were launched in the spring of 1912 with Aberdeen operational by May 1912 and reportedly already having caught "two monster whales."[2] In 1917 Aberdeen was inspected and found suitable for naval service and prospectively assigned identification number ID-763. No record of actual acquisition by the United States Navy has been found.[5]
The vessel is shown active 1930 through 1945 with American Pacific Whaling Company.[1][6]
