February - Production
We have been busy with production the last month, with the Hull and Body department in Medemblik at Contest Yachts and the rest of the team working hard at the Dreamhall. A lot of parts have been produced and the whole team is excited to see our design come to life!
Vehicle Dynamics
The Vehicle Dynamics department has been busy with producing a lot of parts the last couple of weeks. The front struts have been produced by a Dreamhall employee; Salim. Vehicle Dynamics was able to fit the push rods early because of the rapid delivery of those by Van Leeuwen Precisie. The push rods will move up and down in the strut to actuate the foils. Furthermore the foil inserts are produced by Mark on the CNC. These are made of stainless steel and will be laminated into the foils to provide a strong connection to the strut. Moreover, the Vehicle Dynamics department visited our Hull and Body department in Medemblik at Contest to laminate the sleeves and tube assembly into the hull. The sleeves and the tube assembly connect the hull of the boat to the struts. The laminating had to be done neatly since the connection must withstand the full weight of the boat plus the propulsion and wave forces.
The next couple of weeks Vehicle Dynamics will prepare the foil production by designing all the layers and creating digital drawings so that they can use the digital cutter at Rondal where the foils will be produced. Furthermore, Vehicle Dynamics will produce the parts for the height control system and the rear strut will be completed. Next to producing their own parts, the push pull cable arrived from DCS International and the linear technology for the height control from LM Systems will arrive soon as well.
Hull & Body
The past month the Hull & Body department was working on the hull of the boat in Medemblik. In the beginning of January they built the bulkheads and prepared the mould of the hull. The mould was spray painted and waxed to ensure that the hull can be released from the mould properly. After the preparation of the mould, the layers of carbon and core material could be layed. To make the hull ready for infusion, a vacuum bag was built over the mould. The infusion of the hull, the process where the vinyl esther is pulled through the carbon laminate with the use of vacuum, was an exciting moment Hull and Body worked towards these past weeks.
After they infused the hull in the end of January, Hull and Body could start aligning and laminating the bulkheads in the hull. Step by step the hull is coming to life and the engineers can start recognizing the compartments which will soon contain their sub-systems they designed. The coming week, the department is finishing the last parts to prepare to lift the hull out of the mould. A big milestone for the Hull & Body Department!
Embedded Systems
In the last month the Embedded Systems department has been focussing on
getting as many on-board systems working as possible. This meant for example that they calibrated the Emrax electromotor, configured the Brightloop DC/DC converter and updated the Horizon fuel cell. Furthermore, the LiFePO4 battery cells have been wirebonded by Accelonix. This means that it will not take long before the buffer battery is finished.
Embedded Systems worked hard to create and optimise the designs of the Printed Circuit Boards in Altium. These designs were then manufactured by Eurocircuits. Using the components of Würth Electronics, ST Microelectronics and Farnell, Embedded Systems is able to assemble reliable PCBs. They made seven different designs for a total of eleven PCB's that will be used in the boat.
After debugging and testing their PCBs, Embedded Systems will build the internals of the Phoenix Mecano boxes at the workplace of Van der Leun. Van der Leun also helps with the installation of high voltage cabling and they assist Embedded Systems with their knowledge of high voltage systems. The department has also made great progress in their height control system. For the height control they use Maxon motors. The motors respond to control software, which Embedded Systems has developed with consultation by Flying Fish. An ultrasonic height sensor from Senix and an inertial measurement sensor from Xsense will be used to acquire accurate data to control these motors in the proper way.
Recruitment
While the engineering departments are busy with producing different parts of our boat, Operations and Management are also focused on recruitment. Even though we are in the middle of a fantastic year we are already recruiting for the new team that starts in August. In the coming weeks there will be a few different interest moments for those who would like to join the new team. Upcoming interest moments will be on the 21st of February, the 27th of February and the 3rd of March. Do you know someone who might be interested? Let them know they can be part of an ambitious and motivated team to put their knowledge into practice to work on a more sustainable future. The latest details about the application are on our website; www.hydromotionteam.nl

Taking the next step
First of all I would like to wish you a Happy New Year on behalf of the TU Delft Hydro Motion Team. Before the holidays, we had an amazing Design Presentation where we could finally share our design with all of you. Let’s look back briefly on this wonderful night!
Over the last 17 years we have built amazing boats that sail on sustainable energy sources, inspiring the maritime industry to move to a more sustainable future. But now it is time to take action; with our design, it is time to turn the tide.
This year we want to win the Monaco Open Sea Class in July 2023 with our foiling hydrogen-powered boat. With this in mind, we researched the possibilities to reach our goal and we started designing our boat. After making hard choices and working long days we finished our detailed design phase.
The hydrofoils are an important part of our boat because they enable the boat to “fly” above the water, which is called foiling. When the boat is foiling the drag becomes significantly less and therefore we can sail faster with less fuel. With this mechanism we can win the World Championship in Monaco.
Foiling is important to win the Monaco Open Sea Class 2023, because it allows us to reach a similar speed as our competitors who sail on batteries. In order to foil, the boat needs to reach 25 km/h. At this speed, the hydrofoils create enough lift to raise the 1400 kg boat out of the water. Because the competition takes place on the open sea, the boat has to withstand waves that can make the boat unstable. At the same time, the boat also needs to be lightweight to foil. In order to get this done we made some improvements compared to last year.
Hull and Body
The Hull & Body Department has focused on a lighter and more efficient hull shape. The boat has become more efficient by adding the chine, the horizontal ledge, where the bottom transitions to the side. In addition, the bow has been rounded and the boat is optimised for our hydrogen system. This year we’ll have a dead man’s switch, which means we’ll only need two pilots compared to three pilots last year. Because of this, the position of the fuel cell has moved forward and the tanks are placed more to the middle instead of the side of the boat. This allows the boat to be more compact and thus lighter. Ultimately, the weight of the boat affects its foiling characteristics.
Embedded Systems
This year the focus of the Embedded Systems department is to make the electrical system robust and reliable, while keeping it as simple as possible. The department will reuse many components of last year’s boat, such as the fuel cell and the motor controller. However, they will also produce and use many new and innovative components. The department will receive a new, stronger and more efficient motor from Emrax. Besides this, they will make use of a new step-down converter from Brightloop to create the lower voltages needed for all auxiliary systems. The auxiliary systems consist of all systems required in addition to the power system, such as the bilge pumps and display.
We are also designing and producing a new buffer this year, which will have a lower mass and will be safer to use. Lastly, the system architecture and height control system will have a completely new design. The cable tree is redesigned, new Printed Circuit Boards are designed, and the height control system will be designed in such a way that it will be more reliable and responsive.
Vehicle Dynamics
The Vehicle Dynamics department has been really busy designing parts in CATIA for the last 2 months. CATIA is a 3D digital modelling program developed by Dassault Systems. They not only designed the cooling, steering and foil actuation system, but also the driveline, struts and foils. It was a very busy period in which they used a lot of knowledge of our partners and alumni. The Vehicle Dynamics department has been working hard on optimising the height control system. This is the system that will enable us to foil in a stable manner. It consists of the actuation system, sensors and control system. The latter is the custom programmed PID controller, which is a way of optimising the flight characteristics.
Operations department
The Operations department was busy with organising the Design Presentation before the holidays. Not only the content of the presentation needed to be written, but also the music, light, and countdown had to be prepared for the presentation. The department worked hard on organising the drinks and questions afterwards. Besides organising the presentation, Operations actively worked on our social media and press releases, and External Relations worked on staying in touch with our partners.

Production
Now that the design phase is finished, we have started the production phase. Everything we designed will be produced, which is really exciting! From now on we will slowly see our design come to life.
Hull and Body
The Hull and Body department has already started production of the hull at Contest Yachts in Medemblik. During production, the department puts a lot of focus on their personal health and safety. They are wearing proper personal protective equipment which is needed when working with carbon fibre. They are building the hull in a direct mould of about 8 by 3 metres and, despite this size, they were able to set the mould down with a precision of 1 mm. This shows that the department works meticulously to minimise the weight of the boat. The Hull and Body department is now 3.5 weeks into production and they plan to build the hull within 7 weeks.
Embedded Systems
During the coming weeks the Embedded Systems department will be designing, producing and testing all components of the electrical system. There are a lot of different systems, which all have to be controlled by software. The department will design and solder PCB’s, which are debugged and tested thoroughly. After that they will put most of the components in watertight boxes from Phoenix Mecano so that the electronics can be put safely in the boat. We will then connect everything together with cables from Phoenix Contact and Van der Leun so that the data and power can be transferred between the systems. After that everything will be dry tested thoroughly, so that we are sure that everything is working correctly when we test the boat in the water.
Vehicle Dynamics
The coming weeks the Vehicle Dynamics department will produce a lot of parts. Those include parts for the steering and foil actuation, but most importantly: the custom designed foils. The department is going to produce these at Rondal in February. Next to that, the struts are being produced in the Dreamhall with the help of Salim, the CNC programmer of the Dreamhall. Furthermore, the sleeves, which connect the struts with the hull, are also produced in-house. In week 6 we will install those in the boat, which will then still be at Contest in Medemblik, together with the tube assembly (connection between the rear strut and hull).
Operations department
The coming weeks, Operations will be busy with designing the wrap of the boat. Designing the wrap will be done in collaboration with the team through brainstorming sessions and by giving the team the opportunity to voice their opinion about the different concepts of the wrap.
Even though we’ve just had our Design Presentation, Operations is already working on the next event. The Christening of the boat will take place in spring and the department will work on preparing this event in the coming weeks as well.

A new year, a new team, a new boat
Each year there is a whole new team that is eagerly waiting to take over the project of last year’s team. Before I’m going to introduce us I will first look back on the previous team and their performance in Monaco.
Last July, the team of 2022 traveled all the way to Monaco, facing an extreme challenge. They managed to become second in the Monaco Open Sea Class 2022. A huge achievement. There was strong competition in the maneuverability race, nevertheless the team managed to secure an excellent second place. This good start unfortunately could not be continued to the speed section, during the race, the boat suffered from technical defects, which prevented it from completing the race. Despite this being a huge disappointment, the team put in an excellent performance in the final section; the endurance race. With 17 laps, they sailed convincingly to first place after the competitors were far behind. Because the competitors still work with batteries, this also showed the power of hydrogen and its advantages for long distances.
With these results, the team then finished 2nd in the world championship. The entire team is extremely proud that they managed to design, build and race a hydrogen-powered boat in just one year.
To enjoy these moments one more time, the after movie is out now!

Meet the team
Now a new year has arrived with a new team, a new goal and a new boat. Last August, the next generation of the TU Delft Hydro Motion Team started. We spent the last three months studying last year’s boat and designing the 2023 boat with the accumulated knowledge. Our aim is to demonstrate the applicability of new technologies by taking the next step in bridging the gap between the ‘technology of the future’ and the current norm. Within one year, we are creating an innovative boat powered by green energy to demonstrate the potential of sustainable solutions in the maritime industry.
Our goal this year is to win the Monaco Open Sea Class 2023 and become world champions with a foiling hydrogen-powered boat.
To get acquainted with the new team, the team reveal video is out now, which can be viewed here:
