Our team

As team members of the TU Delft Solar Boat Team, we developed world's first single-track hydrofoil boat on solar power in 2013.

We applied many new technologies to this innovative flying boat. This gave us hands-on experience with the most modern maritime solutions.

Soon, we realised our team could improve the future of shipping and water-based moblity

So, we started Flying Fish in 2018 to boost maritime innovations

Today, we are working with eight motivated young professionals. Read about us below

Gijsbert Van Marrewijk

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 completion of his BSc. in Aerospace Engineering, he advised the TU Delft Solar Boat Team during the development of their new hydrofoil boats. Currently, Gijsbert works full time for Flying Fish to bring the future of sustainable waterway mobility closer step by step. At home, Gijsbert likes to play the piano or play board games with friends.

Gerben Schonebaum

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 and started working at high tech company ASML as Control Engineer. Now, Gerben is a co-founder of Flying Fish, working there to improve the efficiency of maritime operations by developing the Watertaxi Operations System (WOS). Outside working hours, Gerben is an experienced sailing teacher and book reader.

Johan Schonebaum

Johan Schonebaum, Msc has graduated 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, where he was responsible for the structural design of the hydrofoils and the assembly and maintenance of the entire boat. Now, he is one of the four co-founders of Flying Fish and working there full-time to realise the Flying Fish vision. Thanks to his experiments on hydrofoil dynamics, he received an Msc. honours programme grade of 10/10. Furthermore, Johan is editor of the book for the BSc. course "Advanced Dynamics". He is not only bright but also very practical, as you can see when you visit his well-maintained sailing boat in the old city of Delft.

Thore Roepman

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. Thore is doing an Msc. in Aerospace Structures & Materials and likes to play volley-ball in the evenings.

Casper Vertregt

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. His interest in crunching data to optimise processes was sparked during an internship as Data Analysis Engineer with the British team challenging for the 35th America's Cup in 2017. He now uses this experience to streamline operations more generally in the maritime sector. Casper is a very enthusiastic team member at Flying Fish and loves to realise new engineering ideas. Besides that, he's very sportive too.

Rijk van Wijk

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 Flying Fish to create the same possibilities for the maritime sector. With Rijk, no software problem is unsolvable.

Olivier Prakken

Olivier Prakken, Msc is an experienced entrepreneur and helps us building a winning organisation. He specifically focuses on overall strategy, team performance and commercial partnerships. He lives in Driebergen together with his wife and 3 young children. He loves Africa, biking and spending time around his barbecue with family and friends.

Tim Visser

Tim Visser, Msc gets a smile on his face from working in the field of data analysis and physics modelling. Tim has finished his PhD thesis at the department of Space Engineering at TU Delft and is now contributing full-time to Flying Fish with expert skills on Research & Development, programming and data analysis. Tim is a cheerful team member who loves to hike.

Martijn Steenbergen

Martijn Steenbergen, Bsc is a programming enthusiast who loves to create software solutions in a structured and well-designed way. With his expertise, Martijn helps Flying Fish to continuously improve the software frameworks that are used for Watertaxi operations, data acquisition and business automation. In his free time, Martijn is a true " Life Hacker ", as he likes creating software solutions to get rid of repetitive chores. In this way he saves time for training at the swimming pool.

Jelle Rieske

Jelle Rieske, Bsc was the Technical Manager at the TU Delft Solar Boat Team 2016. Under his supervision, the project was streamlined and the boat was designed and created in less than eight months. This allowed the team to practise racing for a better performance on the actual race. Currently, Jelle is finishing his Msc in Transportation, Infrastructure and Logistics. He is using his knowledge of mobility and transportation to analyse waterway mobility solutions and to determine waterway potential in hundreds of cities.
