JeffBoat was formed in 1939, immediately prior to WWII, as Jeffersonville Boat & Machine Company, on the site previously occupied by Howard's Shipyard, one on which ships, boats and barges had been built since 1834. JeffBoat was a major builder of LSTs during WWII - wartime employment peaked at 13,000 - and then became the leading inland builder of towboats and barges that it still is today. It has built over 10,000 vessels so far, including over 8,000 inland barges. (source: www.ShipbuildingHistory.com)
