BlueNav continues to innovate with the launch of a brand-new biomimetic design

BlueNav’s engineers drew inspiration from biomimetics to design their new BlueSpin. BlueSpin is now a harmonious blend of biomimicry and sustainable innovation.  



Founded in 2020, BlueNav delivers innovative and environmentally friendly motorisation solutions. Medium-sized boats, usually powered by combustion engines and ranging from 8 to 15 meters in length, can be converted into hybrid electric boats by using these solutions.  


At the heart of their innovation lies BlueSpin, a powerful electric motor equipped with a  retractable, compact, and lightweight design. This motor can be effortlessly installed in both newly constructed boats and existing ones as a retrofit option.  

BlueSpin seamlessly integrates with an advanced navigation system, enabling optimal energy usage scenarios while utilising the motor.  


In their pursuit of continuous improvement, BlueNav’s engineering office embarked on a journey to explore pathways for enhancing the efficiency of BlueSpin motors. After a year of research and technical studies, BlueNav announces a groundbreaking innovation – the Whale Design. Drawing inspiration from biomimicry, their engineers have crafted blades in the shape of a whale's fin.



This innovative design will improve the efficiency of their engines, ushering in a new era of performance. The Whale Design represents a culmination of BlueNav's commitment to innovation and sustainable engineering practices.  


"We are proud to introduce the Whale Design, a testament to our dedication to progress and sustainable engineering. Our mission has always been to push the boundaries of what is possible, and with this innovative design, we are one step closer to achieving that goal." - comments Hervé FROUIN, co-founder & CTO of BlueNav.

Biomimetics design with natural efficiency 


Biomimetics is always a source of inspiration for humans. While nature follows an incremental and random bias for its evolution, humans can mimic designs that are more efficient and quieter, even if, sometimes, they defy traditional engineering theories. Based on CFD (Computational Fluid Dynamics), BlueNav engineers demonstrated that the bumps on the flippers of cetaceans and the striations on their bellies reduce drag and increase fluid flow efficiency.  


The “Whale Design” is available as of the second quarter of 2024.
