What Chartwell Marine does
Chartwell Marine Ltd is an independent naval architecture and vessel design consultancy founded in 2012 and headquartered in Hamble-le-Rice, Southampton, UK, with additional offices in Singapore, Spain and Portugal. The firm specialises in next-generation high-speed vessels, with a core focus on offshore wind crew transfer vessels (CTVs) and service operation vessels (SOVs), supported by a portfolio spanning commercial ferries, patrol and rescue craft, harbour vessels, oil spill response boats, and the Archipelago range of zero-emission explorer yachts. Its proprietary platforms — Ambitious (25.1m), Brevity (27.8m) and Courageous (33.4m) CTV classes, the Midi-SOV, the BARTech30 foiling CTV and the TriFoiler electric trimaran — are validated through CFD analysis and 1:12 scale tank testing, with quantified performance advantages including up to 87% NOx reduction, 38% fuel burn reduction on hybrid daughter craft, and 30-50% better fuel efficiency versus conventional catamarans on the BARTech30.
The company operates a B2B professional services model, generating revenue from design fees, consultancy and vessel partner services spanning concept design, naval architecture, structural engineering and systems engineering. It sells directly to vessel operators, governments and shipyards through enterprise field sales and channel partnerships with major builders including Derecktor Shipyards (USA), VARD (SOV manufacturing), Parkol Marine Engineering (ferry construction), BAR Technologies (foiling technology) and the Cooperative Association of Japan Shipbuilders (CAJS). Customer segments are hybrid: offshore wind operators (primary), commercial maritime operators, government transport authorities and yacht owners. The firm has delivered over 120 vessels globally across Europe, the Americas and Asia-Pacific, employs over 20 specialists, and has secured cumulative grant funding of approximately £2.18 million from Innovate UK and the UK SHORE programme to advance methanol and electric propulsion R&D.
