The team

Meet the team

The team is composed of highly motivated students from a wide range of technical disciplines, including mechanical engineering, electronics, electrical engineering, computer science, naval architecture, and design. Each speciality contributes a distinct perspective, allowing the team to handle every stage of the boat’s development in-house, from hull and naval architecture to propulsion, control electronics and visual identity. This multidisciplinary structure enables a comprehensive and integrated approach to complex engineering challenges, combining technical performance, functionality, and a strong visual identity. Throughout the project, the team operates with the continuous support of experienced mentors from the respective fields, who provide technical guidance, ensure adherence to professional standards, and support the transfer of knowledge from academia to real-world application.

The project’s main innovation lies in integrating lithium batteries and solar energy as the core onboard power sources, in line with sustainable engineering principles. Rather than treating these as separate systems, the team designed the vessel around their combined use from the outset, so that propulsion, energy harvesting and storage work as a single coordinated whole. Through fluid dynamics analysis and structural topology optimisation, we achieved an ultra-lightweight hull while maintaining sufficient structural rigidity, reducing drag and improving overall performance and stability. An efficient onboard power management system was developed to coordinate energy generation from solar photovoltaic panels and energy storage in lithium batteries, continuously balancing supply and demand to ensure optimal power distribution to the electric propulsion system. In addition, a cost-effective, high-performance shock absorption mechanism enhances reliability and stability under varying sea conditions, keeping the platform composed through wakes and chop. Taken together, these choices reflect a clear goal: to advance sustainable marine propulsion technologies, demonstrate the practical potential of hybrid propulsion systems, and set a benchmark for energy-efficient, high-performance electric vessels.
