The carronade was adopted by the Royal Navy in 1779; the lower muzzle velocity of the round shot when fired from this cannon was intended to create more wooden splinters when hitting the structure of an enemy vessel, as they were believed to be deadly.[68] The carronade was much shorter, and weighed between a third to a quarter of the equivalent long gun; for example, a 32 pounder carronade weighed less than a ton, compared with a 32 pounder long gun, which weighed over 3 tons. The guns were, therefore, easier to handle, and also required less than half as much gunpowder, allowing fewer men to crew them.[69] Carronades were manufactured in the usual naval gun calibers,[70] but were not counted in a ship of the line's rated number of guns. As a result, the classification of Royal Navy vessels in this period can be misleading, as they often carried more cannon than were listed.
