Thoma-Sea Shipbuilders
Lockport LA
Most recent update: January 30, 2022.
Thoma-Sea Shipbuilders was started by Walter Thomassie in 2001, when he bought the Lockport shipyard formerly owned by Halter Marine. He then expanded the Houma yard and renamed the combined company Thoma-Sea Marine: visit them at thoma-sea.com. See the Lockport yard, which is on the east bank of Bayou Lafourche, from the air on Google here and the Houma yard, which is on the east side of the Prospect Road bridge here.
