The Team

The Berthan team at Watertaxi Rotterdam

As team members of the TU Delft Solar Boat Team, we developed world’s first single-track hydrofoil boat on solar power in 2013. Because of the revolutionary hydrofoil configuration, the team won the “Design Award” at the 2014 Dong Energy Solar Challenge. In the years that followed, we were often thinking along with our successors in the Solar Boat Team. By doing these things, we could apply our theoretical knowledge from university courses to a real engineering project. This gave us many new insights and has kept us enthusiastic about sustainable maritime innovations ever since.

Gijsbert van Marrewijk, Msc has graduated cum laude in space systems engineering at Delft University of Technology. Back in 2013, he worked full-time at the TU Delft Solar Boat Team as Chief Hydrofoil Dynamics and Stability, where he was responsible for the dynamics of the first solar-powered single-track hydrofoil boat ever. The fruitful year has been rewarded by the Delft University Fund with the DreamTeam member of the Year award. After cum laude completion of his BSc. in Aerospace Engineering, he advised the TU Delft Solar Boat Team during the development of their new single-track hydrofoil boats. Currently, Gijsbert works full time for Berthan to bring the future of flying boats closer step by step.

Johan Schonebaum, Bsc is MSc. student in high tech engineering at Delft University of Technology. In 2013 he worked full-time at the TU Delft Solar Boat Team as hydrofoil engineer in the department of Dynamics and Stability. He was responsible for the structural design of the hydrofoils and the assembly and maintenance of the entire boat. Together with Gijsbert van Marrewijk and Jodi Kooijman he came up with the idea to use only two hydrofoils for the Solar Boat. Johan is editor of the book for the BSc. course “Advanced Dynamics”. Thanks to his experiments on hydrofoil dynamics, he received an Msc. honours programme grade of 10/10. Johan is an enthusiastic student, who loves to make music with his blues rock band.

Gerben Schonebaum, Msc has been the Chief Engineer at TU Delft Solar Boat Team 2014, where he was responsible for the overall design performance of the flying boat. Two years later, Gerben graduated cum laude in Control & Simulation at the faculty of Aerospace Engineering of TU Delft. Now, Gerben is working at Berthan to improve the efficiency of maritime operations.

Thore Roepman, Bsc is not only one of the race pilots of the TU Delft Solar Boat Team, but he also developed the efficient powertrain, a live data-logging device and a 3D flight simulation interface. With this broad engineering skillset, Thore likes to develop new end-to-end systems for improving maritime operations.

Casper Vertregt, Bsc successfully improved the single-track hydrofoil design and control systems of the TU Delft Solar Boat in 2016 to improve the stability and speed. He completed his Bsc. in Aerospace Engineering cum laude in 2015 and is now finishing his Msc in Control & Simulation. Casper is a very enthusiastic team member at Berthan and loves to realise new engineering ideas.

Rijk van Wijk has years of experience in electrical engineering and computer science projects. Thanks to Rijk, the Solar Boat Team has a robust system for live data visualisation during races and tests. In the past few years, Rijk has seen the potential of live data insights to maximise operational efficiency. He is now working at Berthan to create the same possibilities for the maritime sector.

The prize-winning paper could not have been written without our advisor Dr. Ir. Arend Schwab, who has supported us with his knowledge on bicycle dynamics.

TU Delft Solar Boat Team 2013/2014 wins the Design Award for its revolutionary single-track hydrofoil design.
