There were at that period three-deckers of sixty-four guns, and two-deckers of only thirty guns. With regard to the guns themselves, the demi-cannon was probably a 32-pounder, the cannon petro a 24-pounder, and the basilisk a 12-pounder; the whole culverin an 18-pounder, and the demi-culverin a 9-pounder; the saker a 6-pounder, and the mignon a 4-pounder. The smaller guns were called swivels, and were mounted on upright timbers, having a pivot on which the gun traversed. Guns at sea were formerly known by the names of beasts and birds of prey, till about the year 1685 they were designated by the weight of the shot they carried.

In 1688 we find mention made of bombs, which were vessels carrying six or eight light guns, and one or two heavy mortars for the purpose of throwing shells into a town. It is said that they were invented by Reynaud, a Frenchman, and that they were first employed at the bombardment of Algiers in 1681.

In the year 1714 we find the navy divided into ten classes, ships carrying 100, 90, 80, 70, 60, 50, 40, 30, 20, and 10 guns. The first-rate descended no lower than to ships carrying 100 guns; the second no lower than to those of 90 guns; the third admitted all classes below and above 60; the fourth between 60 and 50; the fifth between 50 and 30; the sixth comprised all vessels below 50, except sloops, bombs, etcetera.

By the end of the reign of George the First, ships no longer carried guns on their poops.

The English style of naming the decks of a ship differs from that of other nations, and though perfectly understood by her crew, is calculated to puzzle a landsman. In a one-decked ship the deck on which the guns are carried is called the main-deck, while the deck below it, to which there are no ports, the lower or gun-deck. Hence the term gun-room, occupied by lieutenants or gun-room officers; indeed, the lowest deck of every ship is called the gun-deck. The quarter of a ship is that part of the side which lies towards the stern, and hence that part of the deck is called the quarter-deck, in reference to that portion of the ship’s length over which it originally extended. The elevation above it is known as the poop, and the raised deck over the fore-part of the ship is known as the top-gallant forecastle. In early days, as we have seen in the case of the Great Harry and other ships, and even in later days, both at the fore and after-part of the ship there were elevated structures, very properly called castles. In time these were done away with, but short decks elevated above the main or chief deck were still retained, as it was found inconvenient for the seamen when working the ship to descend from one of these elevated decks and then to be compelled to mount the other to get either fore or aft. They were connected by a grating or gangway of sufficient width to allow the crew to pass backwards and forwards. This gangway was still further widened; it being strengthened by beams running across the ship, allowed guns to be carried on it. The after-part had long been called the quarter-deck, and the fore-part the forecastle, while the intermediate part was now known as the gangway. This name was also applied to the space left in the bulwarks for entering or leaving the ship. These portions of the decks now assumed the appearance of an entire even deck running fore and aft, but it still retained the names originally bestowed on it, and its imaginary divisions. The centre part of the ship, where the gangway is placed, is also commonly called the waist, because originally there was no deck. The deck immediately below this once-divided deck is always called the main-deck. In a three-decker the next is called the middle-deck, and the lowest deck on which guns are carried the lower-deck. Below this again is one still lower-deck called the orlop-deck. A two-decked ship has no middle-deck, but possesses only a main and lower-deck, besides the before-mentioned quarter-deck, gangway, and forecastle. The deck on which a frigate’s single battery is carried is always called her main-deck, because the sailors are wont to denominate the upper-deck of every ship carrying guns the main-deck. In a sloop-ship or corvette the only deck, without any one above it on which guns are carried, is thus invariably called the main-deck, and, as has before been said, the one beneath it on which the officers and crew live, and which has no guns, the gun-deck. Ships which have their only gun-deck running fore and aft for the same height all along are called flush-decked ships. When the after-part of the deck is raised they are known as being deep-waisted, as is the case with many merchantmen. The highest deck of many men-of-war of all rates is often perfectly level, but others have a short raised deck, extending from just before the mizen-mast to the stern, which is called the poop, and in many instances serves as a cover to the captain’s cabin. When the admiral is on board he occupies the after-cabins on the upper-deck. In small men-of-war no cabins are placed under the poop, nor are they ever under the topgallant forecastle. On board merchantmen, however, where the poop is of sufficient elevation and extent to allow of it, the best cabins are always placed under it, while the crew are almost invariably berthed under the top-gallant forecastle. Of course, speaking of men-of-war, we are referring to ships as they were till the invention of low-sided armour-plated craft, which necessitated a great, if not an entire, change of terms, and the introduction of a considerable number of new ones.

Line of battle ships, as their name implies, were such as were capable from their size, strength, and the number of their guns, of entering into the line of battle and contending with the largest ships of the enemy. We first hear of ships appearing in that character in 1691, forming the British Channel Fleet under Admiral Russell. As far back, however, as the year 1614, in a list of the ships of the navy, the line of battle ships are separated from the others. They included all ships from the first-rate to the fourth-rate. A fleet was now attended by smaller, swift vessels, whose duty it was to look out for the enemy, and to perform other detached services. These vessels were comprised in the fifth and sixth-rates, and from an early period were denominated frigates. In early days a large number of fast-sailing or fast-rowing vessels, whether intended for war or for carrying merchandise, were called frigates. The word friggot or frigat, as it was often written, derives its origin from a class of long, sharp vessels used in the Mediterranean, and impelled either by sails or oars, which had a deck, the topside of which was higher than that of the galley. It in general had openings like port-holes, through which the oars passed. An Italian describes the fregata as a little vessel with oars, but whence that name is derived is uncertain. A species of swift-flying sea-gull is called by the French a frégate. We have also the frigate-bird; but the name is generally supposed to be derived from the ship, which, however, may not really be the case. It is very clear that its principal quality was the power of moving rapidly either with sails or oars. The French transferred the frégate of the Mediterranean to the northern shore of their country, and constructed it with bluffer bows and of a large size, to contend with the heavy seas of a northern region. English merchant-ships of the early part of the sixteenth century are frequently spoken of as frigates, and in the latter part of the century were often, as we have seen, hired by the sovereign to serve as ships of war. As we know from the accounts we have already given of the early voyages, some of their ships were denominated frigates. Thus, one of the ships serving with Sir Francis Drake is called the frigate Elizabeth Fownes, of 80 guns and 50 men. The Duke of Northumberland, then Sir Robert Dudley, towards the close of the sixteenth century, designed a ship to measure 160 feet in length and 24 in breadth, and constructed to carry a tier of guns on a single whole deck, besides other guns on two short decks, resembling the poop and top-gallant forecastle of a modern ship. He named his vessel a fregata, and her guns were placed exactly as those of a modern frigate.

He designed at the same time seven distinct classes of ships of war, which he named the Galleon, Ranibargo, Galizabra, Frigata, Gallerone, Gallerata, and Passavolante. His designs not being accepted, he, in the year 1594, built a vessel for himself at Southampton, which measured 300 tons and mounted 30 guns—of course, of small calibre. In her he made a voyage to India.

Charles the First possessed two frigates, the Swan and Nicodemus, each of 60 tons, 10 men, and 3 guns. They probably were only used as yachts. The Duke of Buckingham, who was Lord High Admiral from 1619 to 1636, ordered some frigates to be built from the model of two called the Providence and Expedition, captured from the Dunkirkers, mounting, it is supposed, from 20 to 30 guns, the greater number of which were on a single-deck. In consequence of seeing a French frigate in the Thames, Mr Peter Pett took her as his model for building the Constant Warwick in 1649, which was, as he says, the first frigate built in England. She was intended as a privateer for the Earl of Warwick, who afterwards sold her to the king. She measured somewhat under 400 tons, and mounted 60 guns, consisting of 18 light demi-culverins or short 9-pounders on the main-deck, 6 light sakers on the quarter-deck, and 2 mignons on the after-raised deck, which we should now call the poop.

In those days, and for many years afterwards, the English were addicted to crowding their vessels with guns, and there can be no doubt that many, like the Mary Rose and others, were in consequence lost; especially as their lower-deck ports were often not more than three feet above the water. The Constant Warwick had afterwards many more guns placed in her, so that she ultimately rated as a 46-gun ship, when, from being an incomparable sailer, she became a slug. Mr Pepys remarks on this subject, in 1663 and 1664: “The Dutch and French built ships of two decks, which carried from 60 to 70 guns, and so contrived that they carried their lower guns four feet from the water, and could stow four months’ provisions—whereas our frigates from the Dunkirk build, which were narrower and sharper, carried their guns but little more than three feet from the water and but ten weeks provisions.”

Attempts were made to counteract this great defect, but without much success. For several years afterwards Mr Pepys still complained that frigates were unable to stow a sufficient quantity of provisions, or to carry their guns high enough out of the water to make them safe.
