Waterjets are particularly suited to high-speed planing vessels operating in the 20 to 50-plus knot range, and can be applied to displacement-speed vessels under certain conditions. The company frames its focus around three areas: vessel performance, vessel control, and overall product lifecycle cost. Advantages over conventional propeller propulsion: **Manoeuvrability.** The split duct reverse bucket design gives precise steering at all speeds. Zero Speed steering provides 360 degree thrusting ability for docking and holding stationary, including sideways movement with multiple jet installations, plus high efficiency astern thrust with power-braking ability at speed. **Efficiency.** Propulsive coefficients as good as or higher than the best propeller systems at medium to high planing speeds. Multi-jet installations can continue operating efficiently on fewer drives. **Shallow water and safe operation.** The HamiltonJet intake is flush with the hull bottom, allowing access to shallow water areas and beach landings with no risk of damage to the propulsion drive. There are no underwater appendages, which reduces hull resistance and improves safety around people and marine life. **Reliability.** Waterjets have fewer moving parts, with most major components inboard, minimising the chance of accidental damage and increasing component life. **Maximum engine life.** The impeller is matched to engine power and absorbs consistent power regardless of boat speed, so the engine cannot be overloaded. **Controls.** HamiltonJet manufactures both hydraulic and electronic control components in-house. Competitive claims stated on the page: superior cavitation resistance giving up to 25 percent more thrust than other waterjets between 0 and 20 knots, and a JT steering nozzle that minimises thrust loss when steering with no central deadband. Performance-prediction software supports jet selection. A global network of distributors is present in over 55 locations, supported by regional offices in the USA, Europe and Asia. --- # WATERJETS Source: https://www.hamiltonjet.com/waterjets Positioning: "Waterjets Without Compromise". Having pioneered the modern waterjet over 70 years ago, HamiltonJet waterjets are described as being at the forefront of propulsion technology. More than 60,000 waterjets have been installed into vessels around the globe over the last seven-plus decades, serving boat builders, naval architects and marine operators.

Model-level specifications are published on the HT Series specifications subpage and in the HT Series brochure. Models referenced in HamiltonJet case material include HT810, HT900 and HT1000. --- # CONTROLS Source: https://www.hamiltonjet.com/controls Positioning: "Advanced Vessel Controls". With knowledge honed over 30 years selling and supporting vessel control systems, HamiltonJet designs and manufactures hydraulic and electronic controls for all its waterjet models. Electronic controls can integrate with a range of other vessel systems including engine and gearbox controls, autopilot, voyage data recorders and dynamic positioning systems, to provide complete manoeuvring control. Current range: AVX and AVXexpress. Legacy systems referenced elsewhere on the site include blueARROW and MECS. ## AVX Controls Source: https://www.hamiltonjet.com/controls/avx AVX is HamiltonJet's next generation of vessel controls and its platform for an increasingly connected future, built on three decades of electronic control system experience. It is organised around three pillars: Thoughtful Design, Robust and Reliable, and Future Ready. **Thoughtful design.** AVX is a modular system, scalable for small or large vessels, configurable with up to six control stations and driving up to six waterjets. Steering options include full helm, mini-helm, steering joystick, tiller, or Mouseboat and 3-Axis controller. It offers seamless management of engine RPM and reverse deflector deployment with either combined or separate levers. A screen display gives immediate feedback on system status, critical information, options and settings. Installation includes full integration with common third-party systems such as autopilots and voyage data recorders, compact and lightweight hardware, clearly labelled cabling with top quality Swiss plug-in connectors, and power supplied via dual connections to the battery banks. **Robust and reliable.** Control modules use IP67-rated sealing with extensive shock and vibration tolerance. Many units are potted with epoxy resin to seal electronics from the environment entirely. Swiss-made LEMO connectors are used throughout for robust networking. The system has built-in fault tolerance, a fully dual-redundant architecture and an entirely separate, independent per-jet backup system. Testing includes salt spray, ingress protection, electromagnetic compatibility, impact, UV and endurance, with every unit subjected to extreme temperature and vibration testing in an in-house HALT and HASS chamber. Since introduction, AVX has been proven in dozens of vessels, from rescue boats to fast ferries. AVX is type approved to DNV and has been designed to meet the standards of most other class approval bodies. **Future ready.** AVX enables integration of skipper assistance, autonomous, electrification and digitalisation technologies, including the JETanchor positioning system, precision manoeuvring in close proximity to vessels and fixed objects (with caution), a class approved Dynamic Positioning Interface (DPI) enabling high-end DP systems to command the waterjets, and JETlink as a standardised interface to automated and remote control systems. ## AVXexpress Controls Source: https://www.hamiltonjet.com/controls/avxexpress AVXexpress is part of the same modular AVX suite, cost-effectively scaled for small to medium size vessels. It can be configured with up to two control stations and two waterjets. Steering options include full helm, steering joystick, tiller, Mouseboat or 3-Axis manoeuvring controller. The key hardware difference from AVX: the backup control system is available on the screen display unit, rather than as separate units. It shares the AVX approach to robustness: IP67-rated sealing on control modules, extensive shock and vibration tolerance, epoxy resin potting, Swiss-made LEMO connectors, fully dual-redundant architecture with an independent per-jet backup system, and the same salt spray, ingress protection, EMC, impact, UV, endurance and HALT and HASS testing regime. AVXexpress is not offered with class approval. Named integrations: JETanchor, with Station Keeping and Virtual Anchor modes plus precision manoeuvring near vessels and fixed objects (with caution); JETsense intelligent voyage control, developed in collaboration with Sea Machines, a 3-in-1 helm-based system featuring navigation, multi-sensor fusion and computer vision that can advise, safeguard or assume active control of open water transits; and JETlink, a standardised interface to modern automated and remote control systems. --- # AUTONOMY AND SKIPPER ASSISTANCE Source: https://www.hamiltonjet.com/autonomy Positioning: "Future Ready: Vessel Autonomy and Skipper Assistance Solutions". These systems are described as revolutionising the way vessels are operated, empowering those at the helm to focus on the most critical elements of their jobs, work more effectively and remove people and vessels from harm's way. **Why waterjets suit autonomy.** Waterjets deliver end-to-end integration and interface simplicity. Jet powered vessels turn on the spot, move sideways and perform rapid stops with ease, all without additional thrusters. Changes in thrust direction are delivered with fluid movements of the control surfaces, meaning pin-point accurate station keeping without noisy gear changes wearing out transmissions over long periods. Impellers are safely contained within the body of the jet with nothing exposed beneath the hull, delivering shallow water and unseen debris capability without damage to the drivetrain, and making waterjets safer around people and marine life. ## JETanchor Source: https://www.hamiltonjet.com/autonomy/jetanchor JETanchor is a GPS-based vessel positioning system with two modes: - **Station Keeping:** automatically holds a vessel's position and heading, giving a high degree of positional accuracy. - **Virtual Anchor:** sets a virtual anchor point around which the boat swings with the prevailing conditions, so the boat naturally settles in the most comfortable and fuel efficient heading. When selected with the AVX control system, JETanchor can be used (with caution) in close proximity to other vessels and fixed objects. Station Keeping holds position around the dock, and when the vessel is moved with the manoeuvring joystick or Mouseboat unit the system continues to use GPS position and heading to deliver accurate control around objects, harbours or marinas. Once the manoeuvring unit is released the boat is brought to a halt and returns to Station Keeping mode, eliminating further drift. Operational caveat stated by HamiltonJet: when operating in any JETanchor mode, the skipper must remain at the helm to ensure the safety of the vessel. Deployed on fishing vessels, military, hydrographic survey and recreational craft. Available with AVX and blueARROW systems. ## JETlink Source: https://www.hamiltonjet.com/autonomy/jetlink JETlink is HamiltonJet's autonomous and remote control interface. It uses a proprietary CAN protocol to allow external systems to command the driveline and perform most of the functions of an onboard skipper. The link is made through a compact onboard interface box, and the proprietary protocol can be made available once an NDA has been signed. With more than 10 years of field experience, JETlink is integrated into military, law enforcement, fire and rescue and survey vessels. It is available on all HamiltonJet electronic control systems. ## JETfighter Source: https://www.hamiltonjet.com/autonomy/jetfighter JETfighter is a control interface providing system integration for firefighting (FiFi) vessels. It automates and manages control of the main engine driving firefighting pumps while also allowing the main engine to control the vessel even when automatically station keeping. This addresses the dual-duty engine problem on FiFi vessels, where one main engine simultaneously drives the firefighting pump and propels or holds the vessel. Stated outcomes are reduced operator workload and increased safety during fire emergencies. It is currently available with MECS control systems. --- # ELECTRIFICATION Source: https://www.hamiltonjet.com/electrification and https://www.hamiltonjet.com/electrification/electric-hybrid-drive Positioning: "Future Ready: Electric Hybrid Drive Solutions". Electrification is increasing vessel efficiency, sustainability and productivity, and low noise operations are improving vessel experiences for crew, passengers, bystanders and wildlife. HamiltonJet states there is no one-size-fits-all approach, and that trust and confidence in integration partners is what drives the marine industry's electric transition. **Why waterjets suit electric and hybrid drive.** Electric-only and hybrid drive technologies are described as ideally suited to waterjets, combining the silence and economy of electric drive with the speed and range of diesel. Four platform arguments are given: extremely efficient (consistent, predictable power consumption delivering more capacity for electric power generation), incredibly quiet, highly manoeuvrable (turning on the spot, moving sideways and performing rapid stops without additional thrusters, which simplifies hybrid electric installation), and much safer (impellers contained within the jet body). AVX controls can be easily integrated with most hybrid electric systems. With JETanchor plus hybrid electric, HamiltonJet claims hours of silent, stationary operation without the need to run the engine. **EHX electro-drive system.** HamiltonJet supplies the electric motors, power electronics and control system, alongside specialist expertise to ensure integration with the waterjets, engines, gearboxes or clutches. The control system manages hybrid energy flow between engines, batteries and motors while charging and discharging the batteries as required. An automatic setting enables operation similar to driving a hybrid car, and a manual setting delivers four modes: Diesel Only, Electric Only, Charging and Electric Boost. EHX is scalable, with motors, battery capacity and components selected per project, and the same system can be configured for an electric-only vessel. **Hybrid options.** Customers choose the level of integration support they want from HamiltonJet, matched to project and budget. **Reference vessels** (vessel, application, country, year): HAE YANG No.3 (patrol and military, South Korea, 2023); ARIA (hybrid systems integration, workboat, New Zealand, 2021); Auckland Transport (electric system interface, ferry, New Zealand, 2025); AMARALINA (hybrid interface, offshore, Brazil, 2020); TEIST, Oslo Ports (Norway, 2021); WORLD TERRAL (windfarm, Denmark, 2022); ECO-TENDER (recreational, Italy, 2019); Fullers 360 (hybrid system integration, ferry, New Zealand, 2025); Chungnam Hospital Ship (South Korea, 2024); Annapolis Patrol (jets and controls, USA, 2011); Chasewell Patrol (UK, 2019); SYDNES LC (Norway, 2021); TAMGU No.7 Fisheries (South Korea, 2023); Port Works No.5 (Hong Kong, 2024). **Case study configurations:** 30m hybrid wind farm support vessel (parallel hybrid, electric at lower speeds, generate, diesel for transits); 15m hybrid research vessel (parallel hybrid); 41m hybrid ferry (parallel hybrid); 24m hybrid low emission ferry (series hybrid with shore charging at the home dock); 35m series hybrid ferry (full electric at lower speeds, shore charging); 15m parallel hybrid demonstrator (electric, electric boost, virtual anchor and station keeping, generate and diesel modes). --- # APPLICATIONS ## Search and Rescue Source: https://www.hamiltonjet.com/search-and-rescue Search and rescue is a mission-critical application where propulsion cannot fail. HamiltonJet states that uncompromising standards put durability and reliability at the heart of everything it does, and that its waterjets and vessel control systems work as hard as the vessels they power to ensure mission critical confidence. Waterjet suitability rests on shallow-water access, agility and the ability to operate in poor sea states. The RNLI Shannon Class is described as the most agile and manoeuvrable lifeboat in the RNLI fleet, with its twin HJ364 installation enabling operation in shallow waters. Chinese Rescue and Salvage boats work in very poor sea conditions and weather, and several referenced designs are self-righting. Waterjet models named: HJ364, HJ403. Control and autonomy products named: JETanchor (Korean search and rescue case study). Vessel references: KNRM NH1816 (2014 ship design of the year, 35 knots, 348nm range); NSSR Simrad-class MP1211 fleet of 15 vessels, Norway; Bei Hai Jiu 311 for China Rescue and Salvage with twin HJ403; Korean Coast Guard vessels with twin HJ364; RNLI Shannon Class with twin HJ364; and a 12.5m Volunteer VI rescue RIB to a Kirby Naiad design in Australia. ## Fireboats Source: https://www.hamiltonjet.com/fireboats HamiltonJet's firefighting technology is described as transforming the way fireboats respond to emergencies, built around JETfighter, a completely integrated FiFi interface for fire pump engagement and operation. JETfighter simplifies pump priming and pump speed operation while the vessel manoeuvres and station keeps precisely using the same engines, removing the need to separate propulsion from pumping duty and letting a crew hold position on a fire while delivering water. Operational requirements addressed: precise station keeping while pumping, manoeuvring in confined waterways and harbours, shallow-draft performance, ice operation, rapid emergency response, and sustained duty including extended 24-hour continuous FiFi operation. Products named: JETfighter, HM721 waterjet (Saemangeum 119), MECS manoeuvring joystick control (Yunagi). Vessel references: Yunagi (Osaka Fire Department); IESHIMA (Himeji City Fire Department ambulance vessel); MRV Fire Rescue (Singapore Civil Defence Force); Ranger 2000; Saemangeum 119 (Bi-eung port). ## Patrol and Military Source: https://www.hamiltonjet.com/patrol-boats HamiltonJet positions itself as the most trusted supplier to the patrol and military segment, with over 70 years serving it. Navies, coastguards and marine police globally rely on the company for reliable, robust waterjet propulsion and vessel control, including autonomous and remote-control interface technology. The case is built on speed and agility: referenced vessels achieve 45-plus knots, with emphasis on sprint capability, manoeuvrability, shallow-water operation, extended offshore patrol endurance, search and rescue tasking, and protection of infrastructure in foreign ports. Vessel references: KM Kidurong, a 22.5m Malaysian patrol boat; MKVI Coastal Patrol for the US Navy Coastal Riverine Force; PC Class FIC for the Malaysian Marine Police, on twin HJ403; Rodman-55 Interceptor for the Spanish Guardia Civil at 50-plus knots; and a Tunisia Navy patrol boat conducting SAR and offshore patrols. ## Pilot Boats Source: https://www.hamiltonjet.com/pilot-boats HamiltonJet waterjets coupled with AVX controls enable busy pilot boats to operate flexibly and safely in all conditions. AVX is the explicitly recommended control platform for this segment. The operational argument centres on the transfer itself: pilot launches must hold station alongside a moving ship in demanding sea conditions. Requirements addressed include secure pilot transfer capability, seakeeping, reliable manoeuvring in coastal and inland waterways, extended operational range, and crew safety and comfort including shock-mitigating seating and improved bridge visibility. Reliability under high-utilisation, round-the-clock pilotage duty is a recurring theme. Waterjet models named: HM461 (TE HAA, New Zealand), HJ322 (Trinidad and Tobago pilot vessels). Vessel references: Kurushima and Hayasui for the Licensed Inland Sea Pilot's Association, Japan; Astoria for the Columbia River Pilot Association, USA; a South West Alaska Pilots vessel; TE HAA at the Port of Wellington, New Zealand; the Trinidad and Tobago Pilots fleet; and a Virgin Islands pilot vessel. ## Ferry Source: https://www.hamiltonjet.com/ferry-segment Positioning: "Powering Efficient, Reliable Ferry Operations". The framing argument is that true efficiency is measured at service speed, not just peak performance. Ferries run a repeating profile of docking, acceleration and cruise, so the propulsion case is built around the whole sailing profile. Stated benefits: fuel savings across the full profile without compromising timetable reliability; strong mid-range thrust and efficient steering for acceleration and course keeping; and protected propulsion with no exposed underwater gear, reducing damage exposure and unplanned downtime while extending asset life. Manoeuvrability in and out of berths is treated as a core requirement of high-frequency docking. Series recommended by role: - **LTX Series:** next-generation low-speed jet (0 to 30 knots) with high bollard pull, for commuter and electric ferries. - **HTX Series:** advanced mixed-speed jet engineered for fast ferries needing strong acceleration and precise control. - **HJX Series:** compact high-performance jet for higher-speed ferries operating in demanding, time-critical service profiles. Control systems named: AVX, MECS. Vessel references: Weta Fast Ferries (twin HT810, MECS, San Francisco Bay); Aremiti 6 (quad HT810, MECS, French Polynesia, 36 knots); Nordlight II (twin HT810, AVX, Germany, 450 passengers); Insel Express (LTX36, AVX, shallow Wadden Sea); Apetahi Express (quad HT900, AVX, Tahiti to Bora Bora, 500-plus passengers); Goodna Fast Ferry (HTX42, AVX, 25-knot service, integrated solar). ## Windfarm Source: https://www.hamiltonjet.com/windfarm HamiltonJet describes itself as the number one provider of waterjets to the wind farm support sector, with more than 80 wind farm support vessels currently operational globally. The stated reason for that position is interface simplicity and reliability. The operational case centres on crew transfer: CTVs must sprint to field, then hold hard against a turbine transition piece while technicians step across. Emphasis falls on high manoeuvrability, station keeping and offshore deployment alongside speed and payload. Referenced performance figures include sprint speeds up to 30 knots, continuous operational speeds exceeding 25 knots, and cargo capacity from 10 to 30 tonnes. Sea keeping and trim optimisation and reliable operation in challenging conditions including the North Sea and Japanese waters are also cited. Products named: JETanchor (ICENI Revenge). Vessel references: ICENI Vengeance CTV; ICENI Revenge (23m, JETanchor); MPI Napoleon WFSV; Red Star II (Akita, Japan); WEM 1 and 2 WFSV; WINDEA 4 WFSV. ## Fishing Source: https://www.hamiltonjet.com/fishing The lead argument is gear protection: one key advantage of waterjets for the fishing industry is the low risk of entangling nets or ropes in the jet, because impellers sit contained within the jet body rather than exposed beneath the hull. For a working fishing boat this removes a common cause of downtime, damage and hazardous in-water clearance work. The second argument is workload: control systems enable precise vessel control in all weather, letting crews concentrate on fishing rather than on managing the vessel. Remaining benefits are grouped as manoeuvrability, shallow draft, efficiency and speed. Operational requirements addressed: shallow draft access, manoeuvrability on the grounds, net and rope entanglement prevention, all-weather handling, and crew safety. Vessel references: Allure II, a general purpose workboat serving crayfishing and charter; and Summer, a tuna farm utility catamaran in the South Australian southern bluefin tuna operation doing diver support, maintenance and crew transfer. ## Recreation Source: https://www.hamiltonjet.com/recreation Waterjets deliver manoeuvrability, shallow water accessibility, speed and safety for recreational vessels. Jet-driven boats can turn on the spot, move sideways and perform rapid stops with ease, which is relevant to berthing, beach landings and picking up people in the water. Impellers contained within the jet body give shallow water capability and safety, with no exposed propeller beneath the hull around swimmers and divers. Operational requirements addressed: shallow draft for beach landings, safety around swimmers and divers, high-speed performance (43-plus knots documented), manoeuvring in tight water, and towing and tender duty. Waterjet models named: HJ364, HJ292. Control systems named: blueARROW, JETanchor. Vessel references: T/T Garcon, a landing craft tender for equipment and crew transport plus dive support; BRIZO 46 Motor Yacht, a 45-knot luxury yacht on twin HJ364; Ocean Blu, a multi-purpose ferry, fishing charter, diving and island-hopping vessel running blueARROW and JETanchor; a Safe Boats fast dive tender, a 43-knot offshore dive boat on twin HJ292 carrying 24 divers; and the Wajer Yacht 55 Sport superyacht sports tender. ## Offshore Crewboat Source: https://www.hamiltonjet.com/workboat The propulsion argument is framed around confidence and workload: HamiltonJet systems are thoughtfully designed, robust and reliable, helping vessels work with confidence in the toughest conditions and reducing crew workload so operators can concentrate on critical operational tasks. Operational requirements covered: high-speed personnel and cargo transport, emergency evacuation, station keeping via dynamic positioning, and multi-mission versatility. DP2 notation appears across the case material, indicating dynamic positioning is a core requirement of this segment. Waterjet models named: HT810 (PUMA and PANTHER). Vessel references: Bourbon Sirocco FPSV (wave-piercing bow, DP2); the FSIV Trio West Africa crew boats; Liam J. McCall FSV, a 37-knot ABS-classed vessel; OCEANICA V and VI DSVs on Petrobras charter (DP2, RINA-classed); PUMA and PANTHER FSVs, twin-hull with quad HT810 waterjets; and Rashid Behbudov 70 LCTV, a 38-knot catamaran with walk-to-work capability. Note on URL: this page sits at the /workboat path but is titled and positioned as the Offshore Crewboat segment. ## Aquaculture Source: https://www.hamiltonjet.com/aquaculture Safety around people and stock is the primary argument: with all impellers contained within the body of the jets and nothing exposed beneath the hull, HamiltonJet waterjets are safer around marine life and people. In an aquaculture setting this matters twice over, since divers routinely work under and around the vessel on net inspection and maintenance, and the vessel operates inside pen systems full of mooring lines, nets and live fish. The second argument is positioning. JETanchor is named as the station-keeping system, enabling accurate positioning for drilling and inspection work without anchoring or repeated engine corrections. Other requirements addressed: dive support operations, ROV inspection, low freeboard and shallow draft, and subsea service and maintenance. Waterjet models named: HJ322, HJ364. Autonomy product named: JETanchor. Vessel references, all Norwegian-registered: an aquaculture dive support vessel built around ROV and dive platform work; GEOCAT, a 15m Arctic-capable drilling catamaran running JETanchor; Katrine, 14.9m with twin Yanmar 6LY440 engines driving HJ322 jets; and SARPEN LDSV, twin HJ364 with JETanchor for dive operations. --- # PRODUCT SUPPORT Source: https://www.hamiltonjet.com/product-support HamiltonJet's after-sales support is presented as four linked pillars delivered through a global network of regional offices and over 55 appointed distributors: - **Maintenance and refurbishment:** preventative routine maintenance, repairs and non-routine maintenance, system upgrades and refurbishment, and optimisation and remote monitoring services. - **Parts and consumables:** genuine OEM parts available globally, regional distribution centres, authorised distributors, and interactive spare parts manuals. - **Warranty:** a 3-year standard warranty included as standard, with an additional 3 years available via a HamiltonJet service agreement. - **Training:** mechanical training, electronics training, and crew and operator training.

He died on 30 March 1978. **Ownership.** HamiltonJet remains a family owned company. **Headquarters and manufacturing.** Christchurch, New Zealand, on a 6.88 hectare site with manufacturing floor space of 17,000 square metres.
