What Langham Industries does

Langham Industries is a privately-held, family-owned UK engineering holding company founded in 1980 by John Langham and headquartered in Dorchester, Dorset. The group operates nine wholly-owned subsidiaries serving the marine, motorsport, aerospace, and defence sectors through four core business lines: marine propulsion design and manufacturing (Stone Marine Propulsion, Bruntons Propellers), global marine services and repair (Stone Marine Services, Stone Marine Shipcare, Winters Marine), precision engineering and casting (Stone Foundries, NFF Precision, Tridan Engineering), and port operations (Portland Port).

The company's core technology portfolio includes proprietary propeller systems — Controllable Pitch Propeller (CPP), Autoprop, Autoprop Eco*Star, Varifold, NPT, and Cap Fins — developed and manufactured in-house, alongside 5-axis CNC machining (Mazak i500 with Palletech system), specialist sand casting of aluminium and magnesium alloys, and precision fabrication. Portland Port provides deep-water infrastructure accommodating vessels up to 350 metres in length, while Stone Marine Services operates a 24/7/365 global service network across the UK, South Africa, and Namibia with mobile repair workshops.

Langham Industries generates revenue through direct B2B and B2G sales of proprietary products, project-based professional services, port operations (harbour fees, moorings, commercial estate leasing), and outsourced precision machining partnerships. Pricing is bespoke and quote-based. Customers span naval and defence (Royal Navy, Royal Fleet Auxiliary), commercial shipping, premium yacht builders (Southern Wind, Baltic, Swan, Wally, Oyster), cruise operators, aerospace Tier 1 suppliers, and motorsport racing teams. The group holds AS9100, NADCAP, AWS D17.1, SC21 Bronze, and ISO 14001 certifications, and is currently led by Executive Chairman Christopher Langham following founder John Langham's death in April 2017.

Revenue model

1. Manufacturing and Sale of Engineering Products: Revenue is generated through the design, manufacture, and sale of proprietary products including propellers (fixed pitch, controllable pitch, feathering, folding), propeller components, couplings, and castings for the marine, motorsport, defence, aerospace, and electric vehicle sectors. Products are sold directly to vessel operators, shipbuilders, naval architects, yacht builders, and motorsport companies.
2. Marine Services and Repair: Revenue from maintenance, repair, and servicing of marine propulsion equipment, deck machinery, propellers, thrusters, and stern seals. Services are provided 365 days a year, 24 hours a day, from multiple global locations, to ship owners, vessel management companies, and private boat owners.
3. Port Operations and Commercial Services: Portland Port generates revenue from harbour fees, moorings, ship services (bunkering, marine engineering, hull cleaning), and commercial estate leasing to cargo ships, cruise ships, and other commercial enterprises. The port accommodates vessels up to 350m in length.
4. Precision Machining and Assembly Services: Tridan Engineering provides precision CNC machining, fabrication, welding, assembly, and finishing services to aerospace, defence, specialist automotive, marine, food manufacturing, communication, and medical sectors. Revenue is generated through project-based contracts and long-term outsourcing partnerships.
5. Boatyard and Moorings Services: Winters Marine generates revenue from annual deep-water moorings, storage, repairs, maintenance, and related marine services for leisure and commercial boat owners at Lincombe Boatyard in Salcombe Harbour.
