The Vessel and Her Loss
Aowa was completed in 1918 by the Johnson Shipyard Company of New York for the United States Shipping Board's Emergency Fleet program. She never entered the overseas cargo service she was built for. After the war she was retired and towed to Mallows Bay on the Potomac River, where surveys now describe her as one of the best-preserved wooden steamship wrecks in the sanctuary, though her outer position makes her one of the harder wrecks to reach.
