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 six 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.

Versoix D35 GP: Consistency rules the day, Alinghi wins

3 June, 2018

If you were to be told that 3 x 2 = 1, would you believe it? In pure maths, maybe not. But in sailing, it's possible! By clocking three second-place finishes today, Alinghi won the Grand Prix de Versoix ahead of Racing Django and Swisscom (for those interested, we also placed 4th, but from the four races validated, the worst score is here for the ranking). Following the victory in the Genève-Rolle-Genève yesterday, Alinghi has therefore scored twice this weekend and added only two points in the overall standings of the D35 season. Mid-championship, the team leads the D35 Trophy by four points, ahead of Zen Too (16 points) and Ylliam Comptoir Immobilier (18 points) – click here for the full ranking. Pierre-Yves Jorand: "With no wind on Friday, this Grand Prix was sailed on one day, with four races today. The wind was unusual, and gave rise to a lot of overtaking. It was necessary to keep the head out of the boat and choose the right options. The left side, which was right upwind, was not necessarily the one going downwind. We've won the Grand Prix by only one point ahead of Racing Django and two on Swisscom. It was very tight, but we were the most consistent. This weekend sees the end to a busy period, what with GC32 worlds, travel and training. We'll now have three days of rest before the preparation for the Bol d'Or." João Cabeçadas, shore crew/rigger, said: "We made good starts and we were, practically, all the time on the right side around the marks, with good maneuvers. We controlled our opponents, when it was the right time to do so. From the outside it looks easy, like when you look at a young person who skates in a skate park. But there is a lot of work behind this apparent ease." The team looks forward to welcoming you on Saturday, June 9, from 10am for the starting gun of the 80th Bol d'Or Mirabaud.

D35 Trophy: A second win!

22 May, 2018

Following on from the opening Grand Prix, Alinghi secured another 'Lac Leman' victory at the Open de Versoix. Over the regatta of ten races – sailed amid shifty wind, blowing five to 12 knots – the team won four and finished second three times. Nicolas Charbonnier, tactician, said: "Friday aside, we had great conditions for this Open de Versoix. The key to this event was to keep picking-up points and not to give-up, especially if we had set-backs. The fleet was packed and every mistake was seized upon. Once, we reached the top mark in third place, but ended up, because of a positioning error, in seventh. Another time, we lost our advantage because of a manoeuvre, first to a rival boat and then to most of the fleet. Everything comes down to the smallest detail. "For the coming Grand Prix, we'll have to keep paying attention to these details and continue to sail at the highest level. But I'm not going to say what we're looking to improve specifically, so as not to give our competitors our secrets!" Arnaud Psarofaghis, mainsail trimmer, also noted the increase in the general level of the competition: "The fleet is becoming way closer in terms of performance levels and it shows in the results – three boats finished on equal points! Looking ahead, one of the things we will look to work on is our decision-making at the gate (stage of the race where we can choose between two marks before starting the next leg). Essentially, if we are aiming for a particular side of the race area, we need to be able to accept the bad air and also the proximity of the other boats that have chosen the same mark to keep in touch with the fleet." Alinghi head to Lake Garda this Tuesday for the GC32 World Championship (24-27 May). The D35 resumes on June 1st and June 3rd, again in Versoix for the Grand Prix. The Genève-Rolle-Genève, the first Lac Leman classic, will take place on the 2nd of June. Click here for the general ranking of leg 2 after 10 races.

Mission accomplished

7 May, 2018

After 11 races, raced amid various conditions, Alinghi took the win in the 2018 D35 season-opener in which the team competed against eight rivals. Ylliam-Comptoir Immobilier and Mobimo occupy the other podium places. Ernesto Bertarelli, skipper and helmsman said: "Friday was a big day, but it provided the sort of challenging conditions in which we like to sail. After that day's five races we were leading the fleet with a slight advantage over Ylliam (by one point). Saturday saw slightly lighter breeze with a fleet much more compact. The starts were tight and we had to find every edge - not without risk! – in order to win the legs. "In the end we are pleased with the result, despite some poor performances that, our mistakes notwithstanding, show the high level of our competitors. Ylliam and Mobimo had a great weekend. One with the same crew identical from 2017; the other with a new make-up. "I would also like to acknowledge the Okalys Youth Project, who, for their first regatta together, made a good impression. They even made a top mark rounding in the lead with us. They're very promising." Nils Frei, headsail trimmer, said: "We feel that the teams have trained and improved a lot before the start of this season, perhaps more so in than the other years, especially when we see the performance of Mobimo, which has almost changed all his crew. "Alongside Ylliam-Comptoir Immobilier, we'll need to watch them closely. Not to mention the others, who will make their mark and certainly progress. "At our level, one of our strengths is our ability to raise our heads and not question everything when we have one or two setbacks. More generally, we are happy with the overall performance and with the fact that we didn't make any big mistakes. Anyway, we don't intend on banking this win, but will focus on continuing to work across all facets of our sailing and will look to continue to improve." The team is looking forward to the next D35 event, taking place from the 19th to the 21st of May in Versoix for the season's second Grand Prix. In the meantime, the team heads to Riva del Garda (Italy) on Tuesday for a few days of preparation for the GC32 world championship to be held May 24-27.

On the starting blocks for the 15th D35 Trophy

2 May, 2018

A one-design multihull contest, nine teams competing, and eight races to be run this season on Lake Geneva, as in 2017. So, here we go again as we begin the 15th edition of the D35 Trophy. Things are not exactly the same, however! As a small aside, the weight limit for crews has gone up by 10kg, to 480. During the 'transfer window', some teams have taken the opportunity to mix things up. Not so, Alinghi, the title holder, who return aiming for a seventh victory in the championship and who welcome back the same sailors that were victorious last time. The weather forecast promises – so far at least – wind for the practice day and for the first day of racing, perhaps enough to see the boats hit something-like 25 knots. Let's hope it turns out to be accurate! We look forward to seeing you from Friday 4th to Sunday 6th of May, with six races scheduled per day in this opening D35 Grand Prix, which is organised by our club, the Société Nautique de Genève.   Follow the action You can keep-up with the racing, with up to six races per day in the Grand Prix by: On Twitter @alinghiteam > Updates after each race, as well as photos and video clips On Facebook @teamalinghi and Instagram @alinghi > Interviews, videos and photos On our website > News and photos   To find out more Event hashtags #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.
