When peace returned, Camden grew rapidly. The Megunticook River provided excellent water power sites for mills. In addition to sawmills and gristmills, by 1858 the town had carriage factories, sash and blind factories and blacksmith shops. There were six shipyards, launching ten to twelve vessels annually. By 1886, the town also made foundry products, railroad cars, woolens and paper mill feltings, anchors, wedges, plugs and treenails, planking, powder kegs, excelsior, mattresses, powder, tinware, oakum, wool rolls, boots and shoes, leather, flour and meal, corn brooms and barrels. Camden was second only to nearby Rockland in the lucrative manufacture of lime, excavated at quarries and processed in kilns before being shipped to various ports around the United States until 1891, when Rockport was set off as a separate town. As the 19th century came to an end, Camden was very much a shipbuilding town with the H.M. Bean Yard launching the largest four-masted schooner "Charlotte A. Maxwell" and the first six-master ever built-the "George W. Wells".
