What is the team about?

The TU Delft Solar Boat Team is one of the Dream Teams at Delft University of Technology. Our team consists of 21 ambitious students from eight different fields of study. In one year we go through the process of designing, producing and finally racing a boat that sails on green energy. Our team is fully committed every year to show the applications of our advanced technologies at spectacular races.

For 15 years, we have inspired the maritime industry with our flying solar boats. This year, the 2021 team took the big step with the Hydro Motion project. We are developing our first flying boat that sails on hydrogen! We are moving from generating green energy to storing green energy starting this year.

This project gives our students the opportunity to gain practical experience and learn what it is like to work together in a multidisciplinary team towards an ambitious goal. During one year, they develop in multiple areas and gain skills that will benefit them for the rest of their professional career. With our team we shape the engineers of a sustainable future.

Our mission!

With our project we want to work together with the maritime sector to accelerate the transition to green energy. There is still a lot to be gained in this sector and by thinking together with the maritime world and innovating in the field of sustainability, we contribute to a better and greener future. Because only together we can make a change.




In the history of the TU Delft Solar Boat Team



Have been built in the history of the TU Delft Solar Boat Team

In 2005 several Maritime Engineering students founded the TU Delft Solar Boat Team. A year later, winning the “Frisian Solar Challenge” was set as goal and achieved. Following this success, a second team was founded in 2008 to design an entirely new solar boat. With this, the team was able to prolong its top position.

Every two years a completely new boat was designed and built. The following year this boat was upgraded and optimized, with the current team learning from the mistakes made the year before. However, since 2016 we have decided to build a completely new boat every year instead of optimizing the Solar Boat of the year before.

In 2010 the switch to hydrofoils has been made. This switch introduced a completely new way of sailing. The two teams that followed also used hydrofoils  but were unfortunately not able to win in the Dutch Solar Challenge.

After four years the team went into a new direction. They built a boat that sailed on two so-called struts; T-shaped hydrofoils. While sailing, the hull comes completely out of the water, which is a spectacular sight. With this concept a speed of 51 km/h was reached in 2015, a record within the team. In 2016 that record was broken again with a speed of 55 km/h.

In 2017 the team designed a boat with three hydrofoils. In addition to lowering resistance, the wings now also had the function of improving the stability and manoeuvrability of the boat.

The most important technical development in the Solar Boat of 2018 was the double steering system. Because there were elements in the races where efficiency and manoeuvrability were essential, a system was devised in which the pilot could move the front and rear strut independently. The biggest challenges were to keep it as compact as possible and to guarantee ease of use during the race.

In 2019, the team designed a solar boat for the open sea. With this boat, they became world champions in the Offshore Class in Monaco.

Last year, efficiency was number one. By reducing the size of the sun deck and thus the hull, the resistance was greatly reduced. This enabled the 2020 boat to sail on just the power of a water cooker.

This year, the 2021 team is moving into uncharted waters with our project Hydro Motion. We switch from generating energy with solar panels to storing energy in a green way. This year we build a hydrogen powered boat. To show the potential and power of hydrogen our boat will race at the world championships on the open sea of Monaco.
