Arthur Foss is docked at South Lake Union by the soon to be MOHI.
Wiki: The Arthur Foss, built in 1889, is one of the oldest wooden-hulled tugboats afloat in the United States. In 1898, in response to the Alaskan gold rush, she transported barges full of gold seeking miners and supplies up the Inside Passage. There are no other Alaskan Gold Rush vessels still operating today. She was cast by the Metro-Goldwyn-Mayer movie studio to play in its 1933 production Tugboat Annie. In World War II, Arthur Foss journeyed south to join the war effort. Before the Battle of Wake Island began in late 1941, she was the last vessel to get away. After the war, she served the economy of the Northwest by working in the timber industry.
