Got Any Questions?

We’ve Got The Answers

A good aluminium boat designer will get to know your requirements inside out.  Only then can they create the optimum path to get you building your dream vessel.  Sometimes that will be by using an existing design, sometimes by modifying an existing design or maybe by completing an all-new custom design.

The designer then completes the naval architecture, scantling design, structure design, digital Marine Kit creation, comprehensive construction drawings and nest/cutting file.  All ready for the builder to commence construction without hold ups.

During construction of the vessel a good designer will provide unlimited support to the builder and vessel owner to ensure the build progresses smoothly.

We do all of that but, unlike some designers, the Global Marine Design team goes beyond just ‘ticking the box’.  We spend the extra time required to truly understand your needs, then produce a shipyard-focussed design and drawing set that is simple for the shop floor to understand and build.

This is a tricky one to answer, and the problem is in the question… Every shipyard and every vessel owner is different, so the custom design to suit their requirements will also be different.  It’s super important for you that your designer recognises this and takes the time to tailor a solution to suit.  Does your shipyard use a particular detail for your vents?  Or a preference to build upright or upside down?  Perhaps you’re 6′ 6″ and need extra headroom throughout your new boat?

The takeaway here is we understand that one size does not fit all, and vary rarely fits a few.  This is why we specialise in gaining a deep understanding of your vessel requirements and creating a custom solution to suit.

We’re looking forward to speaking with you about your next build!
