USS YUMA
The USS Yuma was a single-turreted, twin screw monitor of the Casco Class built in Cincinnati by the Alexander Swift & Co., designed for service in shallow rivers, bays, and inlets of the Confederacy. To keep the draft low,armor was sacrificed, but a ballast system was on board to lower the ship in battle.
The Yuma was 225 feet long, had a 45 foot beam and mounted 2 X 11-inch smoothbore Dahlgrens.
Launched May 30, 1865, too late to see action. It was laid up 1866 to 1874 and at one point had name changed to Tempest then back to Yuma. It was sold at auction in New Orleans on September 12, 1874.
