The Hermione's keel was laid on a construction dry dock in the Rochefort
arsenal, close to the Corderie Royale, in 1778.
A ship whose extreme length
spans 65 meters, with 1,500 m2 of sail area divided over 3 masts,
the Hermione was built from plans by engineer Chevillard Aîné.
Along with the Courageuse, the Concorde and the Fée, the ship
was one of a series of four frigates constructed in Rochefort.
Belonging to the category of so-called light frigates, characterized
by their speed and easy handling, the Hermione was outfitted with
26 canons firing 12-pound balls, giving it its nickname of "12-frigate".
At 44.20 m long and over 11 m wide, the frigate required 11 months
of work by hundreds of carpenters, metal workers, drillers, hammerers,
caulkers… prisoners… for a total of over 35,000 workdays.
