About Us

We are 11 young, ambitious and talented engineers with strong ideals for a greener world.

Many of us are TU Delft alumni with a background in Aerospace Engineering, Control Systems, Mechatronics, Computer Science and Structures. Approximately half of our team joined the TU Delft Solar Boat Team during their studies.

In this team we experienced the advantages of hydrofoils and electric powertrains to achieve fast and green sailing. In 2017, we won an award from the International Hydrofoil Society and in 2018 one of our co-founders became Dutch Maritime Designer of the Year. Since then, it has become clear that our focus on sustainable, high-tech maritime solutions is being followed with great enthusiasm from the industry.

Our professional team is applying its expertise in hydrofoils, electric propulsion and data processing on a daily basis.
