How do we build a Sustainable, Circular, Recyclable and Ecological boat with flax and basalt

Flaxfibers are lightweight and flax is a renewable resource that is fast growing in Belgium, Flanders.
Few, if any, fertilizers or pesticides are used in the cultivation of flax. In fact, often flax comes close to the organic standard without trying.
Flax cultivation does not require irrigation and in many cases is fed by natural rainfall alone.
Our 7,5 m boat retains 1 million gram of CO₂.
Flax fibres are lighter than their carbon fibre equivalent, offer better vibration damping than carbon fibre, as well as representing a significantly lower carbon fibre footprint.

In cooperation with:

The basalt fibers are extruded from 100% volcanic rock. Their natural mineral composition gives them unique properties.
They are ecological, contain no chemicals like glass or carbon fibers, have a better LCA profile, and a lower carbon footprint, are recyclable and are made from sustainable basalt mines.
It offers excellent strength and stiffness properties that are better than those of glass fabrics, combined with unique impact and vibration damping.
The basalt fibers are 10-20% stronger and stiffer than glass fibers.

In cooperation with:

Our approach aims to favor “choices” tested by nature which had 100 million years to understand what works best and what doesn’t.
The boat hull is actualy an artificial leaf structural design.
The most exciting thing about Generative Design, is that it challenges our biases. As engineers, we like right angles, flat surfaces and round dimensions, and Generative Design says that may not be the best solution.
It provides us options where to set the veins for the best result.
