The D35 was developed as a response to the ever-increasing costs and extremism in multihull sailing on Lake Geneva. A group of owners, including Ernesto Bertarelli, got together with designer Sebastien Schmidt to bring to life a fast, high-tech, but affordable one-design catamaran. In 2004, the first eight boats were launched, since which the class has gone up to twelve boats built.


When the first D35s were launched in 2004, an annual circuit was created. The Julius Baer Challenge combined the classic Lake Geneva regattas – including the Bol d’Or – with several Grand Prix events exclusive to the D35 class. 

Then called the Vulcain Trophy until 2014, the championship is from 2015 known as the D35 Trophy. As well as the Bol d’Or – the classic end-to-end race on Lake Geneva – it includes the famous Genève-Rolle-Genève, and six Grands Prix. With points awarded for each event, competition for first place on the championship podium is often fierce.

Alinghi is extremely proud to have won five D35 titles, continuing a proud tradition of Lake Geneva sailing.

The design of the D35 is an evolution of Sebastien Schmidt’s previous work, the 40ft Alinghi catamaran Le Black, with a central pod used to tie the structure together and withstand the stresses from the platform and rig. The structure is light, which – when coupled with a wing mast that can be rotated up to 45 degrees and a maximum of 230m² sailplan – means that the boat can hit top speeds of some 27 knots.

Alinghi wins its 7th Bol d'Or!

17 June, 2017

After 5h11m of racing in dream conditions and a real match against Ladycat, Alinghi scored a seventh victory in the iconic Bol d'Or. At the same time, Pierre-Yves Jorand has now equaled the record number of victories for individual sailors, drawing level with Philippe Durr and Philippe Stern. After crossing the finishing line, Pierre-Yves said: "It was an incredible regatta, a duel from start to finish with a great team and great opponents. Last week we lost by a single second to Swisscom in the Genève-Rolle-Genève and so we were certainly hungry. This great victory comes at the right time!” For Nils Frei, the key to the race was the Bouveret rounding: "We passed in second place, just seconds behind Ladycat, but were the first to engage the tack to take us heading back to the Swiss side of the lake and to get the Bise back. It was so rare to have the breezes we did across all of the Lake, but it allowed us to record one of the quicker times in the race’s history – the record being 5h01m. It was a real match with Spindrift, with so little in it." Yves Detrey, known not to be the biggest fan of the long distance races on the lake, did not hide his joie de vivre this time around: "If it's like this next year, I will sign-up right away!" Arnaud Psarofaghis, helmsman of the D35 on this occasion, said: "I am really proud to have won with this team, who are all fantastic. For me the key to the regatta was at the entrance to the ‘Petit-Lac', close to Geneva. We chose a different strategy to Spindrift and it was a choice that paid off." Ernesto Bertarelli: "Congratulations to our Team Alinghi for the great achievement on Lake Geneva today – winning the 79th Bol D’or Mirabaud! It was a fantastic day of sailing, with the famous "Bise" as strong as ever, a focus on skill and tactics and very little place for luck. Congratulations also to Ladycat and its team for being an exceptional competitor in this exceptional race. Every year we seem to encourage each other to do even better, which pushes both teams to perform at their best and is wonderful for the sport.   “I would like to pay a special tribute to Arnaud with whom I have the pleasure to share the helm both on the ESS and the D35 Trophy, as well as to the rest of the team, Pierre-Yves, Nicolas, Nils, Coraline, Yves & João who raced today on board as 7th crew and who is normally part of our shore crew who did an amazing job to keep our boat on top shape! Thank you also to Claudy and David who made sure this victory was technically possible. “And well done to all the boats who took part in the race today, many of which are still on the lake and sailing. “I am really proud to be the Vice-Commodore of SNG which organizes the Bol d'Or every year and I thank also all the volunteers who make this very special event so successful."   The crew will now dedicate their summer to four races in the Extreme Sailing Series (ESS), before returning to the D35 Trophy in September for the last three events of the season.

Genève-Rolle-Genève: 2nd by 1 second!

10 June, 2017

The race committee had to resort to photo-finish to determine the winner of the 2017 Genève-Rolle-Genève, today on the Lake. Alinghi, who led the race virtually from start to finish, finished second in the final, just 20cm behind Swisscom. The nerves of the sailors were put to the test this afternoon, at this, the 53rd edition of the first of the two Lake Geneva season classics. Alinghi sailed a great race, staying ahead of their opponents, on the most part. Swisscom, nevertheless, pipped them to the line, thanks to some bold manoeuvres in the last few metres. "Overall, we are happy," said Nils Frei, shortly after crossing the finish line. "It was a real lake race, with turnarounds, little pressures here and there that we had to try to manage. We had a little concern about our timing at the start, we were not quite on it, but after that we were in the game, and we managed to cope very well with the changing wind." Tactician Nicolas Charbonnier believes he has aged ten years, so intense was the stress: "It was a beautiful Lake Geneva regatta with a few things, many of them tricky, for us to deal with. But we sailed well and I didn’t have to go up the rig to look for the wind pressure. Indeed, when sometimes we had no more wind, there was none anywhere! We just had to be patient.” Arnaud Psarofaghis also noted the stress of the race: "We did not have easy choices, and we did not always agree, but in the end we came together, correctly, and, up until the end, it was a very good fight with Swisscom." Yves Detrey, who is not known for being a big fan of long races, observed: "It's really tiring, not physically, but mentally. Decisions do not necessarily pay off right away; you have to wait and see how they will play out, which is really tough on the nerves. In addition, we had to be careful of the depth as we were often looking for local wind effects very close to shore. With a draft of 2.6m, we obviously don't want to run aground. Pierre-Yves Jorand commented: "We finished second just by one second, which was determined by the last little shift at the entrance mark. Swisscom had a good race, they put us under constant pressure all the way back to Geneva, and they managed to slip their bow just before the line. The race committee did a good job, watching and watching again the videos to finally declare them the winner by a few inches. The approach to these long races has changed over the last five or six years. Now, it is a race in which contact is permanent. Sailors do not take unnecessary risks and so the finishes are even tighter." Click here to watch the live rounding in Rolle with João's commentaries.

A complicated day, but still in contention

9 June, 2017

Alinghi finished the first day of the Realstone Grand Prix in third place, five points behind the leader Ylliam - Comptoir Immobilier. The race committee were successful in launching six races between 15:30 and 19:00, taking advantage of the western flow of 9 to 13 knots of wind. The team’s famous black, white and red multihull did not shine in quite the way that it had in the season’s previous races, with a premature start and tricky conditions being just two of the factors that the crew, who described the day as difficult, had to deal with. "Things were not easy," said Yves Detrey. "We had a bit of trouble finding the right trajectories, taking the right shifts (reading the wind), so it's not a memorable day in terms of performance. There is not much difference in points between us and the race leader, and we are third in the provisional standings tonight. We will have Sunday's races to fix things and to get back on track.” The schedule for Saturday is one that is absolutely synonymous with classic Lake Geneva racing, with a start time for 13:00 no matter which wind conditions. Asked about his view about the racing tomorrow - the Genève-Rolle-Genève, the first of the two major D35 Trophy races taking place - Alinghi's bowman pointed out that a capricious weather could be expected: "It's going to be a long race of light wind, but we're used to it." Follow this link to watch Yves's interview. General standings after 6 races (the worst score being discarded): 1st - Ylliam-Comptoir Immobilier : 2-2-2-6-2-1 = 9 points 2nd - Swisscom : 4-3-4-2-1-2 = 12 points  3rd - Alinghi : 1-5-3-4-3-3 = 14 points 4th - Realteam : 7-6-1-3-4-9 = 21 points 5th - Racing Django : 5-4-5-1-8-8 = 23 points Find all the results at:   Hashtags for the event #GoAlinghiGo  //  #D35Trophy If you want to know more about how to follow the racing, about Alinghi’s team, or just about this regatta in general, you will find all that you need in this news story.

21 May, 2017

Alinghi’s red-hot form in all formats continued today with another win in the D35 Trophy, making it two out of two in the championship’s first two events. Taken alongside the team’s impressive performances on their GC32 in the Extreme Sailing Series, the season has started very well indeed. Alinghi had built up a good lead heading into today’s final day, the third of the Open de Versoix. The wind remained patchy, but when it did blow, four races could be run. Having notched a third-place in the first, the team were unlucky not to secure a win in the second when, having led for much, they were pipped by Ylliam, who took the opposite side on the second beat and found the wind. Still, a second place increased the team’s lead overall, and in the next race, amid a breeze that was threatening to go to sleep and with big differences in pressure across the racing area, the team managed a fourth-place. That was followed, fittingly given the team’s overall performance, by a win in the last race of the day and of the Open de Versoix. Having been in the lead, the win was declared as Alinghi’s as the wind finally gave-up. Overall, a very satisfying performance in challenging conditions and a great way to continue the start of this 2017 racing season, with the team’s lead at the top of the D35 rankings assured. The focus is now on keeping this kind of level throughout the summer, with the D35s back in action on June 9th for the Grand Prix Realstone. Afterwards, Nils Frei was able to give an update on the injury that has kept him away from sailing for the past few events. Speaking in a video that is on the team’s facebook page, Nils confirmed that his foot is a lot better than it was, but that he is still two-to-three weeks away from being able to sail with the team again. His crew send him their best wishes for his continued recovered and look forward to welcoming him back so that he can help them to continue this great run. Final Results Alinghi: 15 points Zen Too: 31 points Ylliam Comptoir Immobilier: 32 points Mobimo: 33 points Racing Django: 36 points Swisscom: 36 points Okalys: 40 points Realteam: 41 points To find out more Photo Credit © Loris von Siebenthal If you want to know more about how to follow the racing, about Alinghi's team, or just about this regatta in general, you will find all that you need in this news story. #GoAlinghiGo
