Atlantic Corp. and L. H. Shattuck Shipyard, Inc., Portsmouth NH

The Atlantic Corp. shipyard was established in 1918, on the site of a failed paper factory in the area of the Piscataqua River Bridge, and folded in 1920.  The company also built a housing estate for its workers, adjacent to the shipyard.  The shipyard site is now occupied by an Irving Oil heating oil terminal, a U.S. Goldbond gypsum board plant and White Mountain Lumber Company.  See the site of the shipyard from the air on Google here.  In Google's maximum magnification, you can just see the shadow of the old launch ways under the water, in line with the axis of the gypsum plant, which must have been built on the foundations used by the shipyard's fabrication shop.  The lumber company's building with the black roof is believed to be the only one on the site that dates back to the shipyard.  The housing estate is just to the northwest, now separated from the shipyard by I-95.

The L. H. Shattuck shipyard was also established in 1918, on a 110-acre site in the Newington section of Portsmouth, and folded in 1919.  The shipyard site was redeveloped by Atlantic Dyestuff Company, which failed in the Depression, and since then the site has been used by a heating oil terminal.  Some of these vessels were unpowered - design 1113 - but it is not clear which.  The remains of the incomplete and abandoned hulls can still be seen at low tide.  See the site from the air on Google here.
