Mangone Shipbuilding, Houston TX

Mangone Shipbuilding was a subsidiary of Stewart & Stevenson, which acquired Anchor Boatworks in 1965 and renamed it. It was sold to Swiftships in 1981, just in time for the collapse of the shipbuilding market. The yard was located on Brays Bayou, at South 80th Street and Brays Street, in the Magnolia Park section of Houston, where the Cronimet recycling yard is today: see it from the air on Google here.
