A Cannery tender was a type of commercial fishing vessel operated by salmon canneries in the early to mid- 20th century. Most commonly used in the Pacific Northwest and Alaska, the tender was used to transport fish from the cannery owned fish traps to the cannery. Tenders were also used to transport men and supplies to set up and maintain the fish traps as well as patrol the area for fish pirates.

After commercial fish traps were banned in Washington in 1934, and in Alaska in 1959, many of the trap tenders were sold to private operators for use as fishing boats or towing vessels.
The Chacon was one of two identical tenders operated by Fidalgo Island Packing Company. The Chacon can be visited at her permanent location in Chugiak, Alaska.
