(b) The most spectacular event in the history of naval architecture in the 18th century was the emergence of the clipper-schooner which became famous during the Revolution. This was a trim, rakish craft known as the Virginia-built schooner, an exclusively Chesapeake type prior to the Revolution. The war created a demand for this fast-sailing vessel and builders all along the coast constructed vessels on the clipper lines thereby converting it to a national type. The war made the clipper-schooner internationally known, however, and before the end of the century, the French, Dutch, and British built schooners on the clipper lines. The pilot boat used in the Virginia Navy was a small fast-sailing craft used as "lookouts", only two of which, the _Molly_ and the _Fly_, were armed. Their duties were attended with many hardships and extreme peril. They were obliged to hover along a dangerous coast in all weathers to give notice of the approach of every sail whether friend or foe. They acted as a flying sentry at the gates of the Chesapeake, but constantly exposed to the broad Atlantic outside. Although the war virtually eliminated Virginia's trading fleet as well as her Navy, her shipbuilding capacity was at its best. Her many shipyards, abundant supplies of available shipbuilding timber, and her skilled craftsmen soon put her trading fleet in operation and it became an integral part of the American Merchant Marine. EARLY VIRGINIA WATERCRAFT (as defined by authorities) _Shallop_--A nondescript type of small boat, from the French "chaloupe," open or half-decked, sometimes with one or two masts for use if needed. It was the most popular boat used in the colony for collecting corn from the Indians, fishing, oystering, and exploring. _Pinnace_--"An old name in English marine nomenclature." A light sailing vessel from the sixteenth to the eighteenth century, decked and having one or more masts, from twenty to thirty tons Burden. The pinnaces _Virginia_, _Discovery_, and the two built at Bermuda, _Deliverance_ and _Patience_ were sea-going vessels. _Barge_--"A term applied to numerous types of vessels throughout the ages." In Virginia it meant a ship's boat, or a flat bottom freight boat used on inland waterways and for loading and unloading ships. _Bateau_--The Chesapeake Bay bateau in colonial times was a double-ended boat having a V-bottomed hull, built in lengths to forty or fifty feet, and was primarily a rowing or poling boat used for rivers and creeks. _Scow_--A large flat-bottomed vessel having broad, square ends and straight sides, sometimes flat-decked. Probably from the Dutch term "schouw." _Flat_--An old form of boat, simple to build, with flat bottom, ends boarded over, used for heavy freight and ferrying, sometimes having a mast. _Skiff_--A light swift open boat, generally double-ended for rowing, but sometimes equipped for sailing.
