What HamiltonJet does
HamiltonJet (legally CWF Hamilton & Co Ltd) is a family-owned New Zealand manufacturer founded in 1939 in Christchurch, where it remains headquartered. The company designs, casts, machines, fabricates, paints, and assembles waterjet propulsion systems entirely in-house, spanning six product series (HJ, HM, HT, HTX, HJX, LTX) and 20 models with power inputs from 150 kW to 5,500 kW, suitable for vessels up to approximately 80 metres. Its broader product surface includes electronic and hydraulic vessel control systems (AVX, AVXexpress, blueARROW, MECS), an autonomy stack (JETanchor dynamic positioning, JETlink autonomous interface, JETfighter firefighting controls, JETsense AI-powered voyage control), and the EHX electric-hybrid drive system for electrified vessels.
The company sells primarily through a global network of 55+ appointed distributors and three regional offices (EMEA in the UK, Asia in Singapore, Americas in Woodinville, WA), reaching more than 70 countries with service support in over 100 countries; 97% of production is exported. Customer segments include fast ferries, patrol and military vessels, search and rescue, fire boats, wind farm support vessels, offshore crewboats, pilot boats, aquaculture, fishing, and recreation, with claimed market shares above 90% in waterjet offshore vessels and leadership positions in ferry and wind farm segments. Revenue is generated through hardware sales of waterjets, control systems, and hybrid drives; an aftersales stream covers spare parts, maintenance, refurbishment, upgrades, training, and a 3+3-year warranty/service agreement structure (up to 6 years of fixed-price service) introduced in June 2025. Capital intensity is high: the Christchurch site has been expanded by 7,500 sqm in October 2025 to 22,500 sqm total manufacturing footprint, boosting production capacity by 40%, and includes in-house foundries for stainless steel and aluminium casting.

HamiltonJet competitors and assessment
Company assessmentDirect peers
- Castoldi S.p.A. Italian manufacturer of waterjet propulsion systems primarily for smaller boats and patrol applications, with overlapping target segments in defense and high-speed commercial craft.
- MJP (Marine Jet Power): MJP (Sweden) manufactures waterjet propulsion systems for high-speed craft, patrol vessels, and offshore vessels, competing directly with HamiltonJet in overlapping power and vessel size segments.
- Kongsberg Maritime (Rolls-Royce waterjets): Kongsberg Maritime acquired the Rolls-Royce commercial marine business (including the former Kamewa waterjet line), making it HamiltonJet's primary direct competitor in marine waterjet propulsion across commercial and defense segments.
Broad incumbents
- Wärtsilä: Finnish marine and energy major providing ship power, propulsion systems (including waterjets historically), hybrid/electric solutions, and lifecycle services — competing with HamiltonJet especially in electrified propulsion and integrated vessel systems.
- Volvo Penta: Volvo Penta supplies marine diesel engines and increasingly integrated hybrid/electric drivetrains and is both a partner and adjacent competitor to HamiltonJet in diesel-electric and hybrid vessel propulsion systems.
- ABB Marine & Ports: ABB competes with HamiltonJet in electric and hybrid marine propulsion, providing power electronics, motors, and integrated propulsion systems for ferries, offshore vessels, and WFSVs.
Others
- Cummins (Marine): Cummins supplies marine diesel and increasingly hybrid-electric propulsion; participates as engine supplier and as system integrator in some segments overlapping with HamiltonJet's hybrid/electric value chain.
- Bruntons Propellers / VARUNA/Yachtcontroller/Marineforce: Bruntons designs marine propulsion propellers and waterjet-adjacent systems; represents the propeller-side competition that HamiltonJet's LTX series is explicitly designed to outperform at low to medium speeds.
Emerging players
- Sea Machines Robotics: Sea Machines is HamiltonJet's collaboration partner for JETsense and an emerging player in autonomous marine navigation; represents the autonomy-stack peer competing for vessel autonomy software integrations.
- ZF Marine Technology: ZF supplies marine transmission, propulsion, and increasingly hybrid drivetrain systems; competes with HamiltonJet's hybrid EHX integration work and offers similar vessel control/monitoring capabilities.
