Within the next 20 years, Lewisville was to become an important shipbuilding center. The extensive forests along the Nanticoke provided abundant supplies of virgin pine, oak and cypress. In 1869, Jonathan Moore of Lewisville established the most important marine railway on the peninsula south of Wilmington. John M. C. Moore, superintendent of Lewisville's Marine Railway Company, originated the well-known Chesapeake sailing ram. This class of sailing vessel was designed as an economical, flatbottom, three masted schooner; its operation required only a small crew. Rams were used for coastal freight primarily on the Chesapeake Bay. Between 1871 and 1918, as many as thirty rams were built in Lewisville shipyards.
