Built in Stockton, California, in 1943 for the U.S. Army, the 75-ton crane is one of the last steam-powered derricks on the West Coast. Foss purchased the derrick following World War II and has used it ever since on Puget Sound and in Alaska.
As an Army vessel, the derrick was designated the BD 800. Its current name comes from a barge numbering system Foss used from the 1940s to the 1960s.
