Boat Building Services
Polaris Marine Group offers specialist boat building services for commercial, government, and private clients across Australia. With a focus on craftsmanship, performance, and marine durability, we design and build vessels that meet the exact needs of their operators, whether for work, transport, or recreation.
Our integrated boat building capability covers everything from steel and aluminium fabrication to outfitting, fitout, and sea trials. We work with clients to deliver new builds that meet specific operational, regulatory, and environmental requirements, with an emphasis on functionality, safety, and long-term performance.
Custom Marine Vessels for Any Application
Polaris Marine Group designs and constructs custom marine vessels to meet a wide range of operational needs. These include workboats, barges, tugs, pontoons, crew transfer vessels, and survey boats, as well as passenger ferries and bespoke craft for harbour or offshore use.
Each project starts with a clear understanding of how the vessel will be used, where it will operate, and the technical specifications it must meet. We then develop a build plan that balances engineering requirements with practical buildability and on-water performance.
We have experience delivering vessels for:
- Port and harbour operations
- Marine construction and maintenance
- Commercial diving and dredging support
- Passenger and cargo transport
- Emergency and utility response
Steel and Aluminium Fabrication
Polaris Marine Group offers in-house steel and aluminium fabrication for marine vessels of all sizes. Our team of qualified fabricators, welders, and marine engineers works to exacting standards, ensuring structural integrity and compliance with Australian and international codes.
We select materials based on the vessel’s purpose and operational environment, including corrosion resistance, impact strength, and weight requirements. All fabrication is carried out under controlled conditions to ensure weld quality, surface preparation, and dimensional accuracy.
We fabricate hulls, decks, superstructures, engine mounts, tanks, and other structural components, with all work certified to the relevant maritime class or flag standards.
Fitout and Outfitting
Once the structural fabrication is complete, Polaris Marine Group undertakes a detailed fitout process to prepare the vessel for service. This includes mechanical and electrical systems, propulsion, fuel and ballast tanks, navigation equipment, and accommodation or control spaces.
We work closely with clients and naval architects to ensure that the vessel’s systems are installed to specification, and that space is optimised for operational efficiency and comfort. Where required, we can install modular systems, wheelhouses, crew areas, and equipment platforms to suit the vessel’s role.
All systems are tested and commissioned in line with safety regulations and manufacturer recommendations.
Integration With Marine Operations
Boat building is not just about constructing a vessel, it’s about creating an asset that performs in the real world. Polaris Marine Group integrates its boat building services with operational marine knowledge, ensuring that vessels are built for the environments and challenges they’ll encounter.
Because we operate our own marine construction fleet, we understand the day-to-day demands placed on marine vessels. This informs our design input, build methodology, and materials selection, delivering boats that are not only compliant, but practical, durable, and efficient.
We build vessels that work as hard as the people who use them.
Project Management and Client Collaboration
Each boat building project is managed by a dedicated team that works closely with the client, designer, and certification authority. From project planning and design development through to fabrication, fitout, and launch, we maintain clear communication and tight control over quality, cost, and delivery timelines.
We assist clients in navigating approval processes, class inspections, and compliance documentation. Our transparent approach ensures that any technical or delivery risks are identified early and resolved proactively.
Clients are welcome to visit the build site, observe progress, and be part of key decision-making milestones during the project lifecycle.
Sea Trials and Handover
Before a vessel is delivered, Polaris Marine Group conducts sea trials to test its systems, performance, and handling. These trials are essential for verifying compliance with design expectations and certifier requirements.
During sea trials, we test propulsion, steering, stability, noise levels, electronics, and navigation systems. We simulate real-world operating conditions to ensure the vessel is safe, stable, and responsive. Any issues are logged, addressed, and resolved before final handover.
Clients receive detailed commissioning reports, warranty documentation, and operational manuals as part of the handover process.
Repairs, Modifications, and Refit Work
In addition to new builds, Polaris Marine Group offers boat repair, modification, and refit services for commercial and government vessels. Whether it’s hull damage, structural upgrades, system replacements, or capacity modifications, our team provides fast, reliable solutions that meet marine standards.
We can drydock, lift, or slip vessels for inspection and works, with minimal disruption to operations. Our experience working on high-use and mission-critical vessels ensures that modifications are delivered safely, efficiently, and with confidence in the outcome.
