Dertona is a Supple and Ballin-type wooden cargo ship built during World War I between 1917 to 1919 for the U.S. Shipping Board as part of the U.S. Emergency Fleet.  Like many of the shipwrecks within Mallows Bay, Dertona was brought to its current location in the 1920’s for salvage.

Dertona is now part of a group of three shipwrecks within Mallows Bay called “The Three Sisters.” “The Three Sisters” include the sites of Dertona, Moosabee, and an unidentified wreck. Dertona lies roughly parallel to the shore and the stern (back) of the vessel is aground on the beach. Today, Dertona is overgrown with plants, but the hull (body) of Dertona is in a good state of preservation.
