Clipper ships are small, lightweight vessels with three masts that boast a massive array of sails which allow them to move extremely quickly. The name "clipper" is thought to come from the fact that the bow of such a ship seems to cut through water as it advances, something also true of older types of ship. Certainly, people were using the expression "to go at a good clip" to mean "to travel quickly" long before the advent of the clipper ship, so the explanation seems to make sense. In fact, it is difficult to date the emergence of the first true clipper, since the word was liberally applied to several speedy ships from the early 19th century that did not possess the technical specifications to qualify as clippers under the later definition of the term. What is known, however, is that by the 1840s, several shipyards were engaged in building vessels that were recognizably clipper ships.
