Commercial Marine Australia designs and builds everything from fishing boats through to naval vessels, yachts, motor cruisers and small recreational boats. Some boats are custom built to a client’s specifications, while others can be built from our existing designs.
Once the customer has determined what kind of boat they want, our CMA shipwrights meets with you directly and discuss the required specifications. CMA prepares drawings for the customer which illustrate how the boat will look, how much it will hold, and how the interior layout will be organised. Once the designs are approved, CMA builds the boat to the approved specifications.
Our goal is to offer our clients the ultimate boat builders Brisbane experience. Let us create for you a new state-of-the-art vessel!
Commercial Marine Australia: Australian Made Aluminium Boats
Aluminium is either used in sheet for all-metal hulls or for isolated structural members. The material requires special manufacturing techniques, construction tools and construction skills. It is the lightest material for building large boats (being 15-20% lighter than polyester and 30% lighter than steel). Aluminium is very expensive in most countries and it is usually not used by amateur builders. While it is easy to cut, aluminium is difficult to weld, and also requires heat treatments such as precipitation strengthening for most applications. It is most commonly used in small pleasure and fishing power boats that are not kept permanently in the water. As qualified boat builders CMA has welders certified to NSCV AS/NZS1665:2004 DNVGL and Lloyds Register standards applicable for all class of vessel.
CMA’s reputation as one of Australia’s best custom boat builders stems from the company’s commitment to innovation; whether it is a special yacht build or the production of a quality pleasure boat or one of our specialist patrol boats, CMA stands for quality.
CMA’s naval architects are professional engineers who design and supervise the construction of sea-going vessels working alongside our marine engineers. It is the naval architect who integrates the activities of a team and takes ultimate responsibility for the overall project. This demanding leadership role requires managerial qualities and the ability to bring together the often-conflicting demands of the various professional engineering disciplines involved to produce a boat.
Our naval architects keep abreast of the latest technological trends and are able to utilise complex computer-aided design and analytical tools. Our job includes making sure our work meets with international safety standards and to ensure that a safe, economic and seaworthy design is produced.
Boats are also brought into our workshop for maintenance, enhancement or refurbishment. Depending on your preferred boat design specifications, CMA will work with different materials and construction techniques in order to assemble or install the interior and above deck components. Refitting boats includes jobs like overhauling, detailing, trimming, engine and transmission maintenance; even the boat’s plumbing and electrical needs are taken care of at CMA.
Our experienced CMA production managers then oversee our team of craftsmen who work on the fit-out. They oversee the installation of marine electrical and electronic systems, the addition of cabin equipment and fittings and coordinate welding, thermal cutting and heating procedures.
As well as managing the team, our CMA refit coordinators work with the customer to identify their requirements and communicate them to the team and to suppliers.
CMA’s marine electricians are some of the best in the business and are responsible for installing, maintaining and repairing the specialised electrical systems required on our vessels, including both DC and AC components. Our electrician’s are responsible for installing or replacing the bridge, cockpit and navigation lights, spotlights or stereo equipment but will also attend to installing and testing snap freezers, holding freezers, portable generators, anchor winches or capstan winches. Depending on the vessel, our CMA marine electricians may also add a 12V radio or TV, or install a 240V converter to run the various AC devices.
CMA can refit an older boat with new wiring and a portable generator to accommodate a microwave, AC TV, inverters for AC or dual supply refrigerators.
CMA has some great marine mechanics who are responsible for performing maintenance and repair work on watercraft equipment.
Our experienced marine mechanics are able to service and repair inboard and outboard boat engines, fuel systems, steering systems, electrical systems, manual starters, and navigational systems on different types of watercraft. CMA marine mechanics have spent years studying the various types of boat engines that are out there and as a result are perfectly placed to advise you on the best power plant solution to your needs. Our marine mechanics are trained to diagnose mechanical, electrical and electronic faults and to do the job properly. You will find our marine mechanics to be easily approachable and happy to discuss details and questions with you, addressing any technical problems our boat owners might have.

- Hot and cold water systems
- Grey and black water control systems.
- Bilge systems, both manual and electric
- Desalination systems
- Fuel systems, fuel treatment and transfer.
Building With Aluminium
The proliferation of aluminium in boat building really took off in the 1960’s with the metal being an appealing alternative to wood and fiberglass. Assembly line-style production kept prices comparatively competitive for smaller builds, with arguably easier usage by owners who deemed the vessels to be lighter in weight and much easier to launch and retrieve.
Aluminium is an ideal material for construction and affords great longevity for our designs. Aluminium also enables us to create fantastic custom designs and build economically. Most importantly aluminium affords the best security for safe cruising.
Aluminium is light, strong, corrosion-resistant, non-sparking and weldable. Because aluminium is not abrasion-resistant, it can be cut with carbide tools. Aluminium is subject to electrolysis, pitting and crevice corrosion, but these liabilities can be managed as long as the installation of dissimilar metals and electrical items are correctly isolated by our CMA technicians.
Aluminium’s lightness can introduce a faster pitching and rolling motion in some hulls. Fairly narrow or light-displacement boats, which tend to have a narrower water plane and less inherent form stability, will benefit most from aluminium construction. Our design engineers and architects will be happy to explain issues with your particular build requirements and offer effective solutions.
An aluminium bare hull, built to the same strength standard, will weigh roughly 25% to 35% less than the same hull in steel. As a result, if high strength is of the highest priority, an aluminium boat can be built to the same structural weight as a steel vessel, and then be considerably stronger. If low weight is the highest priority, then the weight saved will allow the creation of smaller aluminium cruising boats.
There is a lot to be said for aluminium as a material for boat building:
Aluminium is a lightweight material. It weighs three times less than steel. This means that the hull may weigh up to 50% less. A lighter hull offers better performance, a shallower draught, lower fuel consumption and will require less capital outlay for engine and propulsion systems.
Strong and Safe
Aluminium guarantees a stiff and strong boat. Although it has a slightly lower tensile strength, the strength vs weight ratio of aluminium is equivalent to that of steel. There is much less risk of a hole in the hull in the case of a collision, than with a fibreglass hull. This makes aluminium boats safer, especially when at sea, when distances to reach the shore and emergency assistance are often vast.
Long Service Life
Aluminium does not rust. Aluminium reacts very quickly with the oxygen in the air. This results in a thin layer of aluminium oxide on the outside of the metal. Any further contact with oxygen on the inside of the aluminium part is made impossible. Thus, the metal will not be affected by corrosion. The oldest aluminium sea-going yacht – built in 1936 – is still very much afloat.
Low Maintenance Costs
An aluminium yacht does not have to be painted, which reduces building and maintenance costs. An aluminium hull is easy to repair and has little vulnerability to small imperfections such as scratches.
