The larger men-of-war of the period were greater in size than the largest merchantmen. The greater ships-of-the-line (by which expression is meant those which could take their place in the line of battle, the formation of which was in a single extended column) varied from 4,000 to 3,000 tons displacement. The larger of these, which carried guns on three main decks and some light guns on the upper deck, to the number altogether of 100, or even 120, were 180 to 190 feet on the gun deck, with about 53 feet beam. The most usual size, however, was the “74,” carrying nominally that number of guns, but usually six or eight more, on two main decks (and thus known as a two-decker). This class was about 168 feet long on the gun deck and 47 feet broad. Below this class there were many ships of sixty, fifty, or even forty-four guns, with two gun decks. Such, for a long period, formed part of the line of battle. The frigates had but one covered gun deck. They varied in length from 115 to 130 feet on the gun deck, and were from 32 to 36 feet beam, roughly a fourth of their length. They formed no part of a line of battle, their duty when accompanying a fleet being to remain clear of the line and repeat the admiral’s signals. There was also a small class of ship called a sloop-of-war, which carried guns on only the upper, or spar, deck as it came to be called. These vessels were ship-rigged; that is, they had three masts with square sails on each. They were usually about 100 feet long and about 27 feet beam. The three-deckers, or 100-gun ships, carried about 900 men; the 74’s about 600; the frigates about 160. The guns of the period were of course all smooth-bores and muzzle-loaders. In the large ships, the heavier guns, usually 32-pounders, were carried on the lower gun decks to give stability to the ship; 18’s or 24’s were carried on the middle deck, 9’s and 12’s on the upper, 9’s and 6’s on the quarter deck, which was the part of the upper deck aft of the mainmast, and on the forecastle, which was the part of the upper deck forward of the foremast; the space between the two was called the waist. The larger frigates usually carried 18’s on the gun deck; the smaller, 12’s or 9’s. The sloops carried 9’s or 6’s. The greatest range of even the heavier guns was but little over 2,000 yards, as the ports rarely allowed more than 8° or 9° elevation. Such guns were but toys compared with modern ordnance, but they were common alike to all nations, and all were thus on the same footing.
