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.
