BlueNav launches new biomimetic design for BlueSpin family

Electric add-on motor manufacturer BlueNav develops solutions to convert medium-sized boats (ranging from 8m to 15m in length) from ICE to hybrid electric propulsion. Central to the company’s offering is BlueSpin, a powerful electric motor designed to be retractable, compact and lightweight – and which can be installed in newly constructed boats and existing vessels as a retrofit option.

Following a year of research and technical studies, BlueNav has announced an innovation for this series – the Whale Design. Drawing inspiration from biomimicry, engineers have crafted blades in the shape of a whale fin, yielding a design that aims to improve engine efficiency and offer new levels of performance.

“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,” said Hervé Frouin, co-founder and CTO of BlueNav.

Using CFD, 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 will be available in Q2 2024.
