“To successfully carry out a project like SVR-LAZARTIGUE, in addition to passion, you need to have knowledge and experience of the boat,” said Antoine Gautier, design office manager at MerConcept. “Our close collaboration with Dassault Systèmes began in 2011, when we built François Gabart’s first IMOCA-class yacht. We used CATIA to design the boat and all composites parts. We have since moved to the 3DEXPERIENCE platform on cloud and our level of expertise with the solution has significantly evolved.”
Before moving to the 3DEXPERIENCE platform, it was challenging keeping everyone up to date with progress and ensuring they were all working with the latest version. Now, MerConcept has a common data environment, where everyone can work together on the same 3D model – critical for orchestrating all participants and successfully bringing the boat from concept to reality.“If we focus on the design phase, we need to work with tools that are as collaborative, intuitive and easy to use as possible,” Normand said. “Using ENOVIA, the construction and design phase is as smooth as it can be, and that we can support effective information sharing among all the different parties.” With multiple people working on the design at any one time, ENOVIA helps to ensure that technical modifications are correctly implemented, and all affected stakeholders are notified.
“For me, the advantages of the 3DEXPERIENCE platform on the cloud are that we can all interact on the same model,” Gautier said. “Everyone needs to be up to date, so that everyone can see what has been done, and avoid interference issues.”MerConcept’s 3D model of SVR-LAZARTIGUE is a true virtual twin of the physical boat, available in the cloud. This virtual twin is a physically accurate 3D model of the trimaran and its systems viewed in the context of its environment at sea through simulation. It allows the team to virtually design SVR-LAZARTIGUE, complete with all system behaviors, and test it in limitless scenarios. “The virtual twin also allows all relevant stakeholders to access the current model in real time and act on the part or the system that interests them,” Normand said. “Different teams can ‘speak the same language’ and know that what they’re working on is directly linked to what is actually going on in the workshop.”
The fact the 3DEXPERIENCE platform is cloud based has been crucial for collecting and retrieving data when the boat is at sea.
“Thanks to the cloud, we are able to connect from anywhere with an internet connection,” Gautier said. “When we’re on the water, we can access the 3DEXPERIENCE platform and see the boat’s plans and 3D model – critical if we experience any damage or otherwise. We can read the plans and try to understand in more detail what has happened. Thanks to this system, we can bridge the gap between virtual and reality.”
“Thanks to SIMULIA and the 3DEXPERIENCE platform, we have superb depictions of where we can see the streamlines illustrating the air deforming around the trimaran,” Gautier said. “We have qualitative images that allow us to identify the points that cause drag. These visual simulations are very useful and reliable. As a result, we discovered drag marks that we had previously not identified, especially around the rear beam, and this prompted us to modify the fairing geometry.”The simulation results have already helped MerConcept to achieve impressive aerodynamics enhancements. It will be applying further recommendations for future competitions. “Through our work with SIMULIA and their experts, we were able to make significant gains in the boat’s aerodynamics, which I hope will be reflected in exceptional improvements in performance on the water,” Gautier said. “When we have put all the elements we have tested on the trimaran, we should achieve a 70% improvement in the aerodynamic drag. There is no other sector where you can make as much progress as this.”
Backed by the power of the 3DEXPERIENCE platform, MerConcept is not only pushing the boundaries of what’s possible in ocean racing but helping to reinvent the very concept of marine transport to preserve the planet and protect the oceans.“We have this extraordinary ability to cover thousands of kilometers using only wind force to make our boats fly at full speed,” Gabart said. “There is still so much to explore. Now more than ever, we must give meaning to progress so that the future remains full of dreams and promises.”

Antoine Gautier, Design Office Manager, MerConcept:
When you have experienced flying on a boat, it’s an extraordinary feeling and you cannot go back.
00:07 – 00:12
Thomas Normand, CEO, MerConcept:We’ve been able to imagine and build many boats. We took part in many races. We are quite proud of our track record.
00:13 – 00:24
François Gabart, Skipper and Founder, MerConcept:
When you see what has happened, what we’ve been able to achieve, the potential of the boat, we believe that everything is possible for tomorrow.
00:25 – 00:53
Before, we sailed with hulls dragging in the water. Today, we fly above the water. Before, an architect had to work on the shape of the hulls to optimize the drag. Today, we have to work on the aerodynamics to improve the performance of our boat. This is our challenge. Thanks to 3DEXPERIENCE, we have great renderings where we can see the flow lines that we call streamlines. So, we see the air warp around the trimaran. We should achieve a 70% gain in the aerodynamic drag of our trimaran.
00:54 – 01:20
For example, on the SVR-Lazartigue trimaran, it's just over 150,000 hours of work. It's a lot of collaborative work. We use the Dassault Systèmes suite mainly to be able to use the virtual twin, a kind of digital copy of the actual boat that is being built in the hangar. It enables the different teams to ‘speak the same language’ using the most up-to-date version of the design, in phase with what is happening in the workshop.
01:21 – 01:41
Antoine Gautier:Thanks to the cloud, we’re able to connect from anywhere. It allows us to access all the plans and the 3D model of the boat. And it’s typically something we’re likely to do when we’re at sea, in the event of damage, we can read the plans and try to understand what happened in detail. Thanks to Dassault Systèmes, we make the link between the virtual and real.
01:42 – 02:08
We’re very motivated to work on performance improvement, to ensure that these boats can win races and to be able to allow the skippers to deliver messages. And also the R&D and innovation that we develop in our design offices can serve a larger cause. Our business is the sea. So we’re also responsible for reducing our carbon footprint on the oceans.
02:09 – 02:34
François Gabart:To do this, we decided to implement a sustainable innovation lab at MerConcept. We can make technology transfers from ocean racing to yachting, to the transport of people and goods, aiming for the lowest possible impact, and move towards sustainable mobility on the oceans.
02:35 – 02:50
Thomas Normand:That's really what we're looking for today: To win races and make sure we can do it in a meaningful way.
