Thoma-Sea Shipbuilders, Lockport LA
Thoma-Sea Boatbuilders is a small builder of tugs which increased both its capability and its capacity in 2001 by buying the Lockport shipyard formerly owned by Halter Marine. The company does not have a web site, but you can see the Lockport yard from the air on Google here and the Houma yard, which is on the east side of the Prospect Road bridge here.
