Naval artillery in the Age of Sail encompasses the period of roughly 1571–1862: when large, sail-powered wooden naval warships dominated the high seas, mounting a large variety of types and sizes of cannon as their main armament. By modern standards, these cannon were extremely inefficient, difficult to load, and short ranged. These characteristics, along with the handling and seamanship of the ships that mounted them, defined the environment in which the naval tactics in the Age of Sail developed. Firing Firing a naval cannon required a great amount of labour and manpower. The propellant was gunpowder, whose bulk had to be kept in the magazine, a special storage area below deck for safety. Powder boys, typically 10–14 years old, were enlisted to run powder from the magazine up to the gun decks of a vessel as required. A typical firing procedure follows. A wet swab was used to mop out the interior of the barrel, extinguishing any embers from a previous firing which might set off the next charge of gunpowder prematurely. Gunpowder was placed in the barrel, either loose or in a cloth or parchment cartridge pierced by a metal 'pricker' through the touch hole, and followed by a cloth wad (typically made from canvas and old rope), then rammed home with a rammer. Next the shot was rammed in, followed by another wad to prevent the cannonball from rolling out of the barrel if the muzzle was depressed. The gun in its carriage was then 'run out'; men heaved on the gun tackles until the front of the gun carriage was hard up against the ship's bulwark, the barrel protruding out of the gun port. This took the majority of the gun crew manpower, as the weight of a large cannon in its carriage could total over two tons, and the ship would probably be rolling. The touch hole in the rear (breech) of the cannon was primed with finer gunpowder (priming powder) or from a quill (from a porcupine or the skin-end of a feather) pre-filled with priming powder, then ignited. The earlier method of firing a cannon was to apply a linstock—a wooden staff holding a length of smoldering match at the end—to the touch-hole of the gun. This was dangerous and made accurate shooting difficult from a moving ship, as the gun had to be fired from the side to avoid its recoil, and there
