Marine Group Boat Works, LLC

Marine Group Boat Works, LLC, doing business as Marine Group Boat Works, is a Chula Vista, California-based shipyard that constructs, repairs, and maintains naval vessels and small craft for the U.S. Navy and Coast Guard as a prime contractor, operating predominantly under full-and-open competition with selective use of small business set-asides. The company is a child entity of Mgbw, LLC, a for-profit limited liability company structured as a manufacturer of goods and vessel construction and repair specialist.

Marine Group Boat Works' federal footprint centers on vessel construction, maintenance, repair, and alteration services for naval watercraft up to 200 feet in length, with secondary work on ship dismantling, specialized boatyard equipment manufacturing, and logistics support. Representative prime work includes a $5.95 million delivery order (awarded September 26, 2025) under the Marine Boatyard Services 2020-2026 IDIQ for maintenance, repair, and operational support on Landing Craft Utility vessel LCU-1632; a $17.5 million delivery order (awarded September 30, 2024) under the same IDIQ for overhaul and repair of Yard Repair Barge YRBM-29; a $9.65 million definitive contract (awarded September 12, 2023) from Naval Sea Systems Command for towing and dismantling three decommissioned Mine Countermeasures vessels; and a $103,629 definitive contract (awarded June 28, 2026) from the U.S. Coast Guard for underwater side scan capability on the CGC Charles David Jr. The company also executes recurring small-dollar delivery orders for paint floats, barrier boats, brow platforms, and emergency maintenance on active Littoral Combat Ships and other naval craft.

Customer concentration is stark and anchored by a single federal customer. Naval Sea Systems Command dominates both volume and dollars, issuing 461 awards (43% of all 1,070 prime and sub awards tracked) with a combined potential value of $2.44 billion (90% of the $2.7 billion total potential value across all awards). The U.S. Coast Guard, the second-largest customer by award count, issued 274 awards with only $44.6 million potential value—less than 2% of the Navy's total. The Navy Installations Command (174 awards, $18.7 million), U.S. Pacific Fleet Forces (80 awards, $99.1 million), and Military Sealift Command (9 awards, $84 million) round out the top five. This concentration creates acute recompete risk: five awards with combined potential value of $60.3 million are completing within the next twenty-four months.

Marine Group Boat Works sits on four primary vehicle platforms. The Marine Boatyard Services 2020-2026 IDIQ under Naval Sea Systems Command carries 73 task orders valued at $64.3 million combined potential; the vendor also holds an earlier Marine Boatyard Services 2015-2020 vehicle with 109 task orders valued at $38.9 million. The Coast Guard's Indefinite Delivery Contract HSCG4015D53015 generated 264 task orders ($20.2 million combined potential). A GSA Multiple Award Schedule carries 98 task orders ($91.8 million combined potential). An additional Navy vehicle (Indefinite Delivery Contract N0002418D4328) shows 217 task orders valued at $163.8 million combined potential, indicating presence on a second major Navy IDIQ beyond the Marine Boatyard Services platform.

Recent activity has declined. Awards issued per year dropped from 32 in 2022 to 7 in 2026 (year-to-date as of mid-June), suggesting either natural cycle variation in task order placement or possible upstream recompete activity. The Marine Boatyard Services 2020-2026 vehicle, which generates the largest individual awards, will run through 2026; recompete readiness is operationally critical.

In its subcontractor role, Marine Group Boat Works delivers boat repair, critical spare parts support, and technical assessment services to Oasis Systems, LLC (multiple labor and material sub-awards from FY2024–2026), Bowhead Marine Support Services, LLC (critical spare parts and field assessment work in Jordan, May 2025), HII Mission Technologies Corp (fleet training support boat repair work, June–July 2024), Leidos, Inc. (material procurement and SOW support, January–February 2024), and Manson Construction Co (vessel repair during Pier 6 replacement work at Naval Base San Diego, July 2022). Sub-award work is sparse relative to the prime footprint—only 23 of 1,070 total awards are subcontract positions.

Marine Group Boat Works received three federal grants from the Maritime Administration and Naval Sea Systems Command for workforce and infrastructure development. The Maritime Administration awarded $248,402.50 (August 2025) for purchase and installation of a Flow Mach 500 waterjet metal cutting table under the Assistance to Small Shipyards program (CFDA 20.814); $1,142,447 (July 2023) for acquisition of a 100-ton marine travelift, electric forklift, and shuttlelift crane under the same program; and Naval Sea Systems Command awarded $633,005 (November 2025) under the Improvement of Navy Ship Repair or Alterations Capability Program (CFDA 12.031) for a welder training and certification program targeting approximately 100 welders in Tungsten Inert Gas and Metal Inert Gas welding for aluminum alloy groups used in Navy vessel construction. Grant work reflects the company's positioning as a critical Navy industrial base asset facing skilled-labor constraints in the San Diego maritime market.

Service Contract Inventory data captures a narrow and intermittent slice of Marine Group Boat Works' federal services activity: $13.8 million in SCI-reportable invoicing in FY2023 across 11.4 full-time equivalents, with zero invoicing recorded in FY2022 and FY2024. The sparse SCI coverage reflects that most Navy boatyard work—vessel construction and repair—falls under goods/product classification rather than service contract code, and that much federal work occurs at sub-$150,000 thresholds outside SCI reporting. Across the three FY2023 SCI prime records, hourly rates ranged from a 10th percentile of $4,719.71/hr to a median of $23,210.81/hr to a 90th percentile of $41,701.90/hr, reflecting a mixed labor portfolio of shop technicians and skilled trades alongside engineering and management staff.

Marine Group Boat Works operates almost entirely as a prime contractor (98% of awards), building its own delivery teams rather than relying on subcontractor ecosystems. The company competes in full-and-open procurement, not set-aside categories; although some delivery orders carry small business set-aside designations, the vendor's overall posture and award history reflect unrestricted competition. The Marine Boatyard Services and Coast Guard IDIQs constitute the operational backbone of the business, with task order velocity and recompete timing posing the dominant near-term business risks.
