Neafie & Levy was one of the earliest iron shipbuilders and the chief rival to William Cramp in 19th-century Philadelphia. It was started in 1844 by Thomas Reaney, Jacob Neafie and William Smith; Smith died in 1845 and John Levy took his place; Reaney left in 1859 to start his own shipyard in Chester and from then on it was Neafie & Levy, until it closed in 1907. The shipyard was located in the Kensington section of Philadelphia, on land now occupied by a Philadelphia Electric power plant: the plant's pier is believed to date from the site's days as a shipyard. See it from the air on Google here. The table below lists a tremendous number of vessels without much in the way of detail. If anyone can provide any information about this yard and the ships it built, please e-mail it to me at tim@coltoncompany.com
