when construction of the dupont preservation shipyard began
In 1970, Mystic Seaport began construction of the Henry B. duPont Preservation Shipyard, a unique facility with a sawmill, a 90-foot lathe for turning masts and spars and a maritime elevator or lift dock capable of hauling a 375-ton vessel. The Morgan floated free in 1973 after two years of work on her lower hull.
