As the main naval war machine at the end of the 18th century, the 74 Gun Ship was the result of a compromise, like every successful vessel. Her balance between strong guns and manoeuvrability offered by the 28 gun lower gundeck and firing 36 pound cannon-balls, made the "74" the perfect ship of the line. Since she moved more easily, she was much more useful in combat than the heavy 100 gun three-decker.
Her hull alone represented half of 3000 tons moving. 2800 hundred-year-old oak trees (a whole forest), and 600 tons of iron and wood bolts were needed for her construction. The hold and its orlop-deck could contain victuals for 6 months and water for 12 weeks. The gundeck had to bear the considerable weight of enormous 36-pdr guns, weighing 4 tons each. The upper deck, covered front and back with castles, carried lighter guns. This hull rose 7 meters above water and carried prodigious flights of sails. Each of the three masts, in three elements, rigged three floors of square sails and the main top-mast truck towered at 60 meters. This ship was well designed by her engineer and when correctly used by her crew, she performed superbly at sea in all weathers. In a fair breeze, she could exceed ten knots by sailing quartering.
