For some years then after 1851 (the year of 'America's' _début_ here), sails were probably flat enough for the forms they had to drive; and American sailmakers apparently arrived at this conclusion, as they first of all gave up lacing the head sails, and later cut those rounder and rounder, until now American head-sails are cut much fuller than our own, and their mainsails also somewhat fuller. But while the 'America' was undoubtedly the great epoch-making vessel in yacht designing, the cutter 'Mosquito' possessed quite as many original features, and had she only come from abroad instead of being a home production, would have made a far greater stir than the schooner. [Illustration: 'Mosquito,' 50 tons, 1848.] The 'Mosquito' was turned out by the Thames Iron Works Shipbuilding Company. She was designed by that great original genius, Tom Waterman, who had already produced many successful merchant steamers and sailing ships: notably the steamer 'Himalaya,' built originally for the Peninsular and Oriental Company, but afterwards sold to Her Majesty's Government for a troopship, and still a gem of the ocean and mother of the troopers. [Illustration: Midship section.] The 'Mosquito,' besides presenting novelties in form, in the way of an easy and hollow bow, large displacement, well-raked post and deep heel, also upset all preconceived notions of what was yacht fashion, by being built of iron. Great was the discussion over this departure; but, among many prophets of evil, a writer in 'Hunt's Magazine,' in 1854, discussing wood _versus_ iron, predicts that 'the "Mosquito" is likely to be well and hearty when the present wooden craft have gone to that "bourne from which no traveller returns."' This prediction has been exactly fulfilled, as 'Mosquito,' after as long and brilliant a career as has fallen to any yacht, is now, or was a few years ago, doing good work as a pilot boat off Barrow-in-Furness. In 1852, Mr. William Fife, of Fairlie, in Ayrshire, who, with his father before him, had for some years been turning out fast and weatherly boats, produced 'Cymba,' a notable cutter. His father had made Scotch-built yachts, well known by his 'Gleam,' built in 1832, though only fitted out for racing by Sir Robert Gore Booth in 1837; but 'Cymba' was a marked improvement on this model, having a far longer and easier bow, larger displacement, considerable rake of post, and great drag aft. The dimensions of 'Cymba' are appended, and it will be seen that she was just under four beams in length. _'Cymba', built 1852, by Fife_
