Next to the Virginia V is the S.T. Arthur Foss. This steam tugboat built in 1889 first named the Wallowa is probably the oldest wooden tug in the world.

Originally built for Oregon Railway and Navigation Company, she was a harbor tug used for hauling ships and barges along the Columbia River between Astoria and Portland Oregon USA.

During the Klondike Gold Rush in 1898, she was leased to the White Star Line (yes, the same one that operated the R.M.S. Titanic) to two their largest sidewheeler the S.S. Yosemite up the Inside Passage to St. Michael Alaska. On her way back from Skagway while towing the sailing ship Columbia to Seattle Washington, she encountered a strong gale that forced the Wallowa ashore near Mary Island located north of the Portland Canal in Southeast Alaska. Thankfully the Wallowa was recovered and suffered no serious damage, but the Columbia wasn't so lucky and was left stranded at the Portland Canal a wreck. The Wallowa on the other hand was able to make the stormy voyage on the way to Seattle.

In 1904 the Wallowa was purchased by the Puget Sound Mill & Timber Company service in Port Angeles Washingon USA and was used to haul logs from the Crescent Booming grounds near Port Angeles to Bellingham Washington. Near the end of 1929, the Wallowa was purchased by the Foss Launch and Tug Company and was the first vessel owned by the company. However, the company ended up paying so much that they fell down under. To help in paying these depts Foss agreed to donate a certain number of towing services to Merrill and Ring and 2 years later the Wallowa was leased to MGM studios for filming the 1933 blockbuster Tugboat Annie with the Wallowa unofficially being renamed "Narcissus" during her time on set.

The Wallowa as returned to Foss which then she was sent for a complete overhaul at their headquarters in Tacoma Washington USA. The tug would have a complete upgrade, this included a 700 horsepower, 4 stroke, 6-cylinder direct drive diesel engine which made her the most powerful tug on the West Coast. The Wallowa was also renamed after the company's founder Arthur Foss.

In 1941, the Arthur Foss was delivered to the drydock gate in Pearl Harbor in early of March 1941 for service in the port. She was meant to be returned to the West Coast however she was chartered by Foss to serve at a consortium of civilian engineering firm. She was put into service hauling barges of gravel between Kanehoe and Honolulu for the construction of airport runways, then in June that year, the tug was reassigned to hauling construction materials and military supplies for airfields and barracks in the same area. With tensions arising between the USA and Japan, it was clear that the USA was preparing for war. Then in December that year, it happened. The Japanese came to Pearl Harbour and started an air raid, bombing ships in the harbor. The Arthur Foss was harnessed into service and was painted gray using a mixture of white paint and engine grease, aware of the risk of being bombed or torpedoed. The Arthur Foss ended up being the last vessel to escape from Wake Island after it was captured by Japanese forces.

After the war the Arthur Foss was brought back to the West Coast. Foss based her at their Port Angeles location after major repairs where she spent her post-war life hauling logs as she did before being purchased by Foss. These voyages ran under the contract of various logging companies. After an overhaul in 1964 she was renamed the Theodore Foss in honour of Thea Foss' eldest brother-in-law, due to the company's new ocean-going tug being given the name "Arthur Foss" The Theodore Foss was retired in 1968 and was moved to Tacoma where she sat idle for the next 2 years.

The Theodore Foss was donated to the Northwest Seaport Volunteers by Foss in 1970 who gave her back her pervious name, and they refurbished her main engine. In 1980 there was an official startup of the Arthur Foss as a museum ship. Today she is docked at the Historic Ships Wharf on Lake Union in Seattle accompanied by many other historic vessels including the Virginia V.
