Little is known about Continental Iron Works, which apparently only built one ship, except that there is no apparent connection between this yard and the Continental Iron Works that was located in Brooklyn NY and that built several monitors, including the original "Monitor". If anyone can provide any information about this shipyard, or about the ships it built, please e-mail me at tim@coltoncompany.com
