Mangone Shipbuilding, Houston TX
(formerly Anchor Boat Works, later Mangone Swiftships)
Most recent update: May 9, 2012.
Mangone Shipbuilding acquired Anchor Boatworks in the mid-1960s: it failed in 1981, when the offshore market collapsed, and was acquired by Swiftships, but closed permanently a year later. It was located at South 80th Street and Brays Street, in the Magnolia Park section of Houston: see the shipyard from the air on Google here.
