In 1872 Mr. N. G. Herreshoff, the younger of the two brothers connected in yacht-building, and the designer, brought out the 'Shadow,' 37 ft. over all, a sloop whose fame is still fresh in the mind of every yachtsman in America. She has won more races than any American yacht, and even to-day can give the best of the new yachts a very hard pull. The 'Shadow' has the honour of being the first yacht built on what was afterwards known as the 'compromise model'; that is, a design that combines the beam of the American with the depth of the English yacht. From her earliest performance 'Shadow' showed speed and admirable qualities, but strangely enough, her form was not reproduced nor copied for nearly fifteen years, which may be accounted for in a measure by her designer having deserted the yachting field and turned his attention to steam engineering and to the designing of steam yachts. Mr. Herreshoff, however, did not wholly abandon his interest in sailing vessels, and occasionally put forth a sailing yacht, or more properly boat, one of which, the cat-boat 'Gleam,' was very famous for speed both in native and English waters. [Illustration: Lines and midship section of the 'Shadow,' designed by N. Herreshoff, 1872.] Another well-known cat was 'Alice,' 1879; she took twelve first prizes out of eleven starts during her first year, in one race there having been two prizes offered. During the ten years from 1860 to 1870, covering the period of the War of the Rebellion, yachting interests were at a low ebb, and comparatively few pleasure vessels of any kind were built.
