A clipper was a very fast sailing ship of the middle third of the 19th century. They were fast, yacht-like vessels, with three masts and a square rig. They were generally narrow for their length, could carry limited bulk freight, small by later 19th century standards, and had a large total sail area. Clipper ships were mostly constructed in British and American shipyards, though France, Brazil, the Netherlands and other nations also produced some. Clippers sailed all over the world, primarily on the trade routes between the United Kingdom and its colonies in the east, in trans-Atlantic trade, and the New York-to-San Francisco route round Cape Horn during the California Gold Rush. Dutch clippers were built beginning in the 1850s for the tea trade and passenger service to Java.
The boom years of the clipper ship era began in 1843 as a result of a growing demand for a more rapid delivery of tea from China. It continued under the stimulating influence of the discovery of gold in California and Australia in 1848 and 1851, and ended with the opening of the Suez Canal in 1869.
The term "clipper" most likely derives from the verb "clip", which in former times meant, among other things, to run or fly swiftly. Dryden, the English poet, used the word "clip" to describe the swift flight of a falcon in the 17th century when he said "And, with her eagerness the quarry missed, Straight flies at check, and clips it down the wind." The ships appeared to clip along the ocean water. The term "clip" became synonymous with "speed" and was also applied to fast horses and sailing ships. "To clip it," and "going at a good clip," are familiar expressions to this day.
While the first application of the term "clipper" in a nautical sense is by no means certain, it seems to have had an American origin when applied to the Baltimore clippers of the late 18th century. When these vessels of a new model were built, which were intended to "clip" over the waves rather than plough through them, the improved type of craft became known as "clippers" because of their speed.
