Expect Vendée Globe time to be crushed

Published on November 3rd, 2020

VPLP, a world-renowned young international team of French-based naval architects and designers, are nearly ready to exhale. With the start of the Vendée Globe on November 8, they can ease back and watch the evidence of their hard work race around the world. In this report by VPLP, they share a view of the past four years since the last race:


The Vendée Globe is always a special moment for VPLP Design, especially since the firm’s designs, in collaboration with Guillaume Verdier, won the last two solo round-the-world races.

Of the seven new boats built specifically for the previous edition of the Vendée Globe, six were designed by the architectural partnership of VPLP Design and Guillaume Verdier. This time round, the eight “2020 generation” boats taking the starting line were designed by four naval architects: VPLP Design (3), Juan Kouyoumdjian (2), Guillaume Verdier (2), and Sam Manuard (1).

According to Vincent Lauriot-Prévost, VPLP co-founder, this rivalry changes everything: “The challenge has taken on a new dimension. Previously, we had to do the best we could; this year we’re having to do better than the others. The choices we’ve made are going to be vulnerable to criticism, which is exciting but much less comfortable!”

Consequently, designers have had to stick their necks out! “We knew nothing about what the other teams were doing when we started working on Charal and Hugo Boss,” recalls Lauriot-Prévost. “We had to take some risks, otherwise the pitfall would have been to design an average boat and we could not allow that to happen.”

According to Quentin Lucet, VPLP naval architect, this led to a radical change in the firm’s approach to design.

“We stand by our choices,” explains Lucet. “The generations of 2008 and 2012 embodied the quest for lightness and power; while the foilers of 2016 sought a compromise in that they could always rely on the keel if the foils failed. All the hulls we’re fielding in 2020 only work with foils.”

In other words, the desire to reduce drag has replaced the quest for more power. “We weren’t afraid to go for it and, fortunately enough, it’s exactly what the teams of Jérémie Beyou (Charal) and Alex Thomson (Hugo Boss) wanted.”

With just three projects in the VPLP portfolio – Charal, Hugo Boss, and DMG Mori (sistership to Charal) – the team was able to concentrate all our efforts on this latest Vendée Globe campaign. “Because only half the number of boats were taking the line this time round, we were able to organize more preferential support,” says Lucet.

“This facilitated dialogue and created a climate of trust. We were sailing more often with the teams, too… We were aboard Charal again just days before she left for Les Sables d’Olonne. This fostered a certain continuity which was very fruitful.”

Adrien Letourneur, VPLP egineer in charge of performance for the Jérémie Beyou project was “working almost full-time for Charal,” says Lauriot-Prévost, “which only happens very rarely.”

This new way of interacting with the teams was all the more necessary because the boats really needed it. “The teams were more demanding and their design offices were expanding,” says Lucet. “Between 2005 and 2016 the time spent on architectural design and the structure increased fivefold. And for this particular Vendée Globe, it grew another 50%! As for the design studies, they doubled in duration compared to the previous campaign, from three to six months.”

As a result the surge in performance is expected to be greater than the usual advances made from one Vendée Globe to the next. “We’ve stepped up a gear,” says Lauriot-Prévost. “Compared to the 2020 generation, the foils of 2016 were matchsticks!” Lucet calculates the performance gains of the new foilers between 70° and 100° off true wind to be “between 20% and 30% compared to their predecessors.”

Each Vendée Globe campaign sees the development of new tools. “Progress has been relentless over the last twelve years,” says Lauriot-Prévost. “What’s new for VPLP Design is that we’re now developing these tools in-house with support from Gurit for the structural calculations. We’ve got all the specialists in the same room, and this increases our responsiveness and flexibility to a considerable extent.”

Now with its very own simulator (SYD), an extremely accurate velocity prediction program (VPP), and increased calculating capacities, the firm is now equipped to delve much deeper into the details.

“Today, we can study in much greater detail how a given foil design works because we know how to calculate its distortion – its twist – and the attendant changes to its angle of attack,” explains Lucet. The same goes for optimizing existing boats: “Thanks to the simulator we have a much clearer idea of how our proposed improvements are going to work. Performance gains and dynamic behaviours are markedly better quantified than previously.”

MACSF (formerly Safran and Queguiner) and SeaExplorer Yacht Club de Monaco (formerly Edmond de Rothschild) have all directly benefited from these powerful new tools during recent extensive optimizations, in particular the addition of new foils.

Despite the sustained advances in the design and construction of the boats, the skipper’s role continues to be an essential performance parameter, perhaps more than ever on this Vendée Globe. “The race is going to lay bare the skippers’ capacity to exploit their boats,” explains Lauriot-Prévost. “The number of parameters they need to master in order to arrive at a good compromise in terms of trim and performance is just enormous.

“We’ve arrived at such a level of complexity that the experience gained from the time spent sailing prior to the race will be even more decisive than before.”

What will be the operating percentage of these ever more demanding boats? “I think we’ll see close to 100%,” says Lauriot-Prévost, “because the skippers have never been better.”

Lucet is betting they will shave two to four days off the time recorded by Armel Le Cléac’h in 2016–17 (74 days 3 hours 35 minutes and 46 seconds). “The VPP are giving a race time of 65 to 70 days with the maximum run in the polar seas,” he says. “But we’re always more surprised by the performances of the skippers in the real world rather than in our simulations!”

The Vendée Globe is the only sailing race round the world that’s solo, non-stop, and without assistance, and it is all systems go for the 9th edition on November 8, 2020. Beginning in 1989 with 13 entries, the start line on November 8th has 33 skippers set to take off from Les Sables d’Olonne, France.

The development of the IMOCA Class toward foiling will see these boats hurl themselves around the world, teetering on carbon skates through inhospitable regions, chasing the record set in 2016-17 by Armel le Cléac’h of 74:03:35:46.

Participation history:
1989-90: 13 boats at the start
1992-93: 15 boats
1996-97: 15 boats
2000-01: 24 boats
2004-05: 20 boats
2008-2009: 30 boats
