Ship of the line
Very large ship bearing between 60 and 100 guns on 3 decks. They had three masts and a bowsprit. The bow (the front) of the ship was lower than the stern (the back). Regarding its rigging, ships of the line had three rows of square sails. These were sails set perpendicular to the keel (which is to say, to the ship). Ships of the line had secondary rigging (jibs) set on the axis of the keel (parallel to the ship), of triangular, trapezoid or square shape.
