On July 2010, archaeologists encountered the intact remains of a ship’s hull in lower Manhattan. Because the date of construction and origin of the timbers were unknown, samples from different parts of the ship were for dendrochronological dating and provenancing. After building a floating chronology from the extracted white oak samples, absolute dating and provenance was evaluated against 21 oak site chronologies. The year 1773 showed the strongest evidence for the tree felling date prior to construction. Higher agreement was found between the ship chronology and two chronologies from Philadelphia and eastern Pennsylvania. Our analysis suggest that the timbers used to build the ship originated from the same specific location, supporting the independent hypothesis that the ship was built in a small shipyard. Few 18th century ships have been found and there is little historical documentation of how vessels of this period were constructed. The hull represents a rare and valuable piece of American shipbuilding history.
