USS Wassuc (1865)
USS Wassuc — a single-turreted, twin-screw monitor — was built by the George W. Lawrence & Co., Portland, ME, and launched 25 July 1865, and completed 28 October 1865.
Wassuc was a Casco-class, light-draft monitor intended for service in the shallow bays, rivers, and inlets of the Confederacy. These warships sacrificed armor plate for a shallow draft and were fitted with a ballast compartment designed to lower them in the water during battle.
