What St. Johns Ship Building does
St. Johns Ship Building, Inc. (SJSB) is a Jones Act-compliant, HUBZone-certified full-service shipyard headquartered at 560 Stokes Landing Rd., Palatka, Florida, on the St. Johns River approximately 68 miles south of Jacksonville. The company specializes in the new construction and repair of aluminum and steel vessels — including crew transfer vessels (CTVs), ferries, tugboats, barges (deck, spud, tank, and stop-log variants), landing craft, offshore supply vessels, and cargo vessels — for U.S. government agencies (notably the U.S. Navy and U.S. Army Corps of Engineers) and commercial marine operators in offshore wind, marine construction, infrastructure, and marine equipment rental. Its production infrastructure comprises an 850-ton dry dock, 500-ton crane capacity, 2,400 feet of waterfront with 900+ feet of bulkhead, a 400-ft launch basin, two rail launch systems, a 425-ft by 75-ft fabrication shop, CNC routing for non-ferrous metals, and ABS/USCG/DNV certified welders; vessels are classed under USCG, ABS, DNV, and BV.
SJSB generates revenue through project-based contracts for new vessel construction and marine repair services, with pricing established via custom quotes based on vessel specifications, materials, and project scope. Its go-to-market is direct enterprise and government field sales — responding to U.S. government RFPs (U.S. Navy, U.S. Army Corps of Engineers) and negotiating commercial contracts directly with operators such as Atlantic Wind Transfers, WINDEA CTV LLC, and Johnson Bros. — supplemented by industry event participation and thought-leadership positioning via President Joe Rella's testimony before the U.S. House Committee on Transportation and Infrastructure. The yard's design partners include Incat Crowther and Chartwell Marine, and its modernized production capacity supports concurrent vessel construction across steel and aluminum programs.
SJSB is a privately held subsidiary of Americraft Marine Group, which was launched in 2022 by the privately held Libra Group (20 businesses across aerospace, renewable energy, maritime, real estate, hospitality, and diversified investments in nearly 60 countries). The 2022 acquisition triggered facility upgrades, workforce expansion, and equipment modernization — including a 100-ton Link-Belt rough terrain crane acquired in October 2025 through MARAD's Small Shipyard Grant Program. Since 2024 the company has delivered five Jones Act-compliant CTVs for the offshore wind market, secured its first U.S. Navy DSV contract in May 2025, and continued to win barge construction awards from government and commercial customers.
