The French navy especially, under the fostering care of Colbert, was greatly strengthened. During the i8th century it was con stantly found that the dimensions of French ships exceeded those of British ships of the same date, and that French vessels were superior in speed. This led from time to time to an increase of the measurements of the various classes of vessels in the British navy. These were now rated according to the number of guns which they were constructed to carry.
"Royal George," launched in 1756, was the result of an effort to improve the line-of-battle ship of the period. She was 178 ft. in length, 52 ft. in beam, was of over 2,000 tons, and carried 1 oo guns and a crew of 75o men. The "Victory," Nelson's flagship, was built nearly ten years later. Her dimensions were 186 ft., 52 ft., 2,162 tons, and she carried ioo guns. During the same period frigates, which were cruisers carrying their armament on one deck, were built to carry 32 or 36 guns, but in this class also the French cruisers were superior in speed and of larger dimen sions. The remainder of the 18th century and the beginning of the 19th witnessed a continuous rivalry in naval architecture, the French and Spanish models being constantly ahead of the British in dimensions and armament. In the American war (1812) the same disparity as regards dimensions became apparent, and the English frigates, and sloops used as cruisers, were generally out classed, and in some instances captured, by American vessels of their own rate. This as usual led to the construction of larger vessels with greater speed, and though, after the conclusion of the long war, the activity of the royal dockyards slackened, yet the great three-deckers of the last period, before the adoption of steam power, had reached a length of over zoo ft., with more than 55 ft. beam, and over 3,00o tons. (For the further development of warship construction, see under the respective classes, e.g., BATTLESHIP, CRUISER, DESTROYER, etc.) The end of the Napoleonic Wars heralded a very great change in the construction of merchant ships and the conduct of the shipping business, so that the years 1815 and 1816 mark the beginning of a new epoch unusually clearly. The steamship was firmly established, but her uses were very limited and the sailing ship was still predominant.
