Steaming around Puget Sound for 100 years
About the Ship: Engineering
The Virginia V’s engine is one of two identical steam engines built by Heffernan Engine Works for the U.S. Government. One was accepted and installed in the U.S. Army Quartermaster Steamer Evan Thomas, and the other was sold in 1904 to the Lorenz Brothers for the Tyrus, later renamed Virginia IV.
After the Virginia V was launched, the brand new hull was towed to to the King Street Drydock in Seattle where on April 2, 1922, the engine, boiler and condenser were transferred from the Virginia IV to the Virginia V. In a disastrous turn of events, loose engine mount bolts allowed water to fill the hull of the Virginia IV and she sank. Six months later she was raised, and sold to Canoe Pass Packing Company. They re-powered her with a diesel engine and used her as a cannery tender.
The ship was restored 1996-2002, with the final project completed winter 2005, and preserved by The Steamer Virginia V Foundation. Learn more about her triple-expansion steam engine on this virtual tour of the engine room.
