About J&H Marine
J&H Marine, a Stockton, California-based small business Subchapter S corporation, provides marine vessel repower, overhaul, and repair services to the Department of the Interior as a prime contractor exclusively under total small business set-asides. The vendor operates across NAICS 336611 (ship building and repair) and related maintenance codes, delivering engine replacement, hydraulic system installation, hull inspection, electrical and navigation upgrades, and sea trials for federal research and resource-management vessels.
J&H Marine's customer base concentrates entirely within Interior. The Department of the Interior Bureau of Reclamation accounts for 7 awards valued at $652 thousand (50% of combined potential value), while Interior's Fish and Wildlife Service regions—particularly Region 8—supply the remaining awards. The vendor has executed 14 prime contracts since 2013, all under total small business set-asides, with no subcontract work in the source record.
Recent capability examples include a $423.5 thousand definitive contract awarded May 13, 2026, to repower and overhaul the R/V Confluence research vessel with a QSM11 engine replacement, Vickers hydraulic pump, mast replacement, hull preservation, and sea trials at the contractor's Pittsburg Marina facility, running through December 31, 2027; a $149.8 thousand purchase order from May 2023 for diesel repowering of the 30-foot R/V River Rat with a Cummins QSB6.7 engine and Konrad sterndrive (ultimately completed March 2024); and a $9.7 thousand repair order for the FWO Threadfin vessel awarded April 2026. Activity has remained sparse and irregular—one to two awards per year in recent years, with the sole near-term recompete exposure being the $424 thousand R/V Confluence contract reaching ultimate completion in late 2027. J&H Marine operates as a sole-source Marine service provider to Interior and has not yet positioned itself on multi-award federal vehicles or across other customer agencies.
