Chimo I (Monitor)

(Monitor: t. 614; l. 225'; b. 37'; dr. 6'6"; dph. 9'1"; cpl. 65; a. 1 11" sb.)


The first Chimo, a light-draft ironclad monitor, was built by Aquila Adams at South Boston, Mass., from plans by John Ericsson; launched 5 May 1864; and commissioned 20 January 1865, Acting Master John C. Dutch in command.

Chimo sailed to New York, arriving 26 January 1865, to be fitted with torpedo gear and one 11-inch Dahlgren smoothbore gun. On 1 April 1865 she departed for Hampton Roads where she arrived on the 9th. On 28 April she sailed for Point Lookout, N.C., where she served as a station ship until 28 May 1865. Arriving at Washington Navy Yard 7 June 1865, she was decommissioned 24 June 1865. Her name was changed to Orion 15 June 1869; to Piscataqua 10 August 1869, and she was sold in 1874.


On 24 February 1919 the unfinished Chimo (AT-22) was renamed Tadousac (q.v.).
