Bucentaure-class ship of the line

The Bucentaure class was a class of 80-gun French ships of the line built to a design by Jacques-Noël Sané from 1802 onwards, of which at least 29 were ordered but only 21 ships were launched. They were a development from his earlier Tonnant-class ship of the line.

Armament
As built, the first two ships of this class carried the same 80-gun armament as their predecessors of the Tonnant class - thirty 36-livre guns on the lower deck, thirty-two 24-livre guns on the upper deck, and eighteen 12-livre guns plus six 36-livre obusiers (howitzers) on the spar deck above (the French livre was about 8% greater than the British pound weight, so that the 36-livre round equated to 38lbs 13.6oz).

Under the 1806 règlement, the spar deck ordnance was altered to fourteen 12-livre guns plus ten 36-livre carronades. Subsequently, additional 36-livre carronades were carried by most later ships of the class, raising them to 86-gun ships (with variations in actual numbers).
