We combine professional design knowledge with on-water practical experience to deliver advanced vessels, designed for export anywhere in the world. Located in Western Australia, the GMD team have designed and kitted an extensive portfolio of commercial designs, luxury and pleasure craft.

  • 3D Modeling

    We utilises a variety of software packages to create dimensionally accurate 3D models of vessels even before they are built. The software is used to make direct measurements, calculate areas and volumes and perform a full array of design calculations.


    Our primary product is our pre-cut aluminium Marine Kits®. Once designed, the entire boat is pre-cut and flat packed in Complete Knocked Down (CKD) form for shipping. We guarantee the kit’s materials, precision, consistency and accuracy, providing better outcomes for our clients.


    We offer a range of engineering services including the provision of complete vessel engineering systems design and documentation to required survey codes, structural design and finite element analysis, mooring design, lifting arrangements and more.


    Services include Australian NSCV plan approvals, stability approvals or initial surveys for all domestic commercial vessels.


    We offer our consultation services for Naval Architecture, vessel design and performance estimation, stability manuals and a range of Engineering. Our staff are available to travel worldwide to deliver on site results with fast turnaround times.
