Class. Plans for this ship by Prétot were approved in 12.44. Her engines were of the double traverse type, which combined some of the improvements of direct-acting engines with a connecting mechanism resembling the traditional side lever. This ship and the smaller Anacréon appear to have been the only French naval ships with this type of machinery: both did well on trials, but the machinery was almost as large and heavy as traditional side-lever engines. The beam outside her paddle boxes was 55ft 10in. Originally named Socrate, she was renamed 11.11.46.

Disposal. Prony was wrecked in the Gulf of Mexico.

COLBERTCherbourg5.6.455.5.481.7.49Stk. 15.4.67

Class. In 12.44 the minister approved the construction of Colbert on plans drafted in 2.44 by Pironneau for Roland, which was later reprogrammed as a screw corvette. Colbert's 320nhp engines were standard side-lever engines on Fawcett's pattern. The ship consumed a large amount of coal, 40 tons per day at full power, and her small sail rig gave her only 5.7kts with wind astern. The beam over her paddle boxes was 56ft 4in.

Disposal. Colbert was BU 1867 at Rochefort.
