Personalise this vessel

We understand that owning a boat is a very personal experience, and we want to help make your boat uniquely yours. We offer the ability to personalise your vessel. Such as increasing fuel capacity, changing engine arrangements, adding or removing doors and hatches, and much more. To get started…

Step 1. Simply tell us what you have in mind, whether it’s a list of changes or sketches of your ideas.

Step 2. We’ll provide you with a fixed price quote that includes any estimated material costs. In the rare case that material costs increase, we reserve the right to charge you for any additional costs. Once you’re ready to proceed, you’ll pay a deposit to secure your place in our project pipeline.

Step 3. When your turn comes up, we’ll begin designing your personalized modifications. We’ll send you images and/or a 3D viewer file to review, and you can provide any minor changes needed. Once you’re satisfied with the design, we’ll create your personalised kit.

Step 4. Finally, you’ll receive your customised kit, just like any standard kit.
With our personalised services, you can make your boat truly one-of-a-kind.

Do you sell boat plans and designs?
In most circumstances, purchasing kits offers greater cost-effectiveness and a wider range of advantages. The first kit in any model includes a licence to build 1 boat. When purchasing future kits of the same model we don’t charge any licencing fees. Kits also include the PDF Construction Drawings and Calculations.
In some circumstances, we are able to sell the 2D CAD Cutting Files. The rights of use of those files differ depending on the situation. This may include single-use, minimal multi use, or unlimited use. In places that we offer kits single use is generally not available. Because of this, you’re purchasing multiple licenses at once and therefore the prices are higher.
In locations where it’s hard to get cutting or even large sheets supplied we offer a full-scale Paper template option. This comes with a license to build 1 boat, all the construction plans, and every part as a paper template in full scale.
Is a Jig Required to Build Your Boats?
No. Our kits are designed to be pulled up on the floor. Once done all that is needed is some props to stabilise the hull.
If you’d like to create a cradle for We can supply what you need to create a cradle for the boat if you like.
The reason we don’t require jigs is we spend extra time in the design phase and complete full studies on every plate to ensure there is limited stress in the plate. No stress, means the plates come together with limited fuss, thus not requiring a jig.
Can you arrange a Builder, or help with fitout?
Yes, absolutely. We work with a network of builders operating all over. When you request final price, tell us what you need and we’ll give you options of who to go to.
We have our certified builders list also.
As we work with builders often they will give us better prices, we can also offer discounts for going through our certified builders. So let us help you with some quotes.
Would you supply a kit to my location?
We currently service the whole of Australia, New Zealand, Canada (US sales shipped from here), and the UK(European kits shipped from here)
