The Séduisant class was a sub-class of 74-gun ships of the line of the French Navy, comprising two ships built at Toulon Dockyard to a design by Joseph-Marie-Blaise Coulomb in the year immediately following the close of the American Revolutionary War. In reality these two ships followed his design for the Centaure class, but were completed with a length greater by 5¼ feet, and had also slightly less breadth and depth in hold.
^The ship's measurement in 1783 was 173 pieds 3 pouces. The units of measurement pieds (feet) and pouces (inches) were units of measurement in France before the French Revolution; they were slightly larger than the equivalent British feet and inches.
