Two-deckers in general
Two-deckers were sail warships widely used in the 18th and 19th centuries. They carried their guns (70-90 cannons) on two fully armed decks and their crew consisted of 500-700 men.
They were also called ships of the line (french. vaisseau de ligne) from the line formation during battle, where the two columns of opposing warships maneuvered to fire with their cannons along their broadside.
