The _Sovereign of the Seas_ in Fig. 61, reproduced from an engraving in the British Museum, after the picture by Van der Velde, owes her design to Pett also. The reader will see how much nearer his craft approaches to the old wooden walls of the eighteenth century. Built in 1637, this vessel was for the next generation the admiration and envy of foreign nations. Like the _Prince Royal_ at a later date, she was cut down in 1652 to a two-decker, having been found somewhat crank. But as originally constructed, the _Sovereign of the Seas_ was a three-decker—the first of her kind—and her measurements, probably taken on the gun-deck, were: 169 feet 9 inches long, by 48 feet 4 inches beam, the depth of her hold being 19 feet 4 inches. She had a tonnage of 1683 burthen, and her anchor weighed 60 cwt. Designed by one member of the Pett family, Phineas, she was built under the supervision of Peter Pett. In 1684 she was practically rebuilt and then renamed the _Royal Sovereign_, but twelve years later had the misfortune to be burnt accidentally at Chatham, yet not before she had done excellent service under Blake and others during the seventeenth century wars. Notice in the illustration that instead of the rare use of the topgallant at the main, she carries them on all three masts: further still, observe the fact that by now royals have come into use for the first time. The fore and main have them stowed with yards lowered.[96] Originally the _Sovereign of the Seas_ had four masts. She carried over 100 guns; had a figurehead; and the beak-head, though somewhat similar to that of the _Prince Royal_, is placed lower, while the length of the ship is proportionately greater, and the original tubby appearance of the _Prince Royal_ is improved upon. There is a medal of the time of Charles I., commemorating the Declaration of Parliament of 1642. On one side is shown a conventionalised design of this or a similar ship, showing both topgallants and royals, the latter stowed.
