Arkema Sailing

As partners since 2013, Arkema and Lalou Multi decided in 2019 to give a new dimension to their collaboration, still anchored on the common values of innovation and a quest for performance. The construction of the new trimaran Multi50 Arkema 4, the result of close collaboration between both partners’ teams and experts, will be completed in 2020.

With its young skipper Quentin Vlamynck at the helm, the boat is scheduled to be launched this Summer before engaging in a program of races, depending on the health situation.

The team spirit that drives this partnership is reflected in the transmission of knowledge from the skipper, coach and entrepreneur Lalou Roucayrol to Quentin Vlamynck during training periods or in duo or crewed races.

The Arkema’s Sailors



Quentin Vlamynck, skipper of the future Multi50 Arkema 4

Quentin’s adventure began four years ago with the construction of the Arkema 1 trimaran. Under an apprenticeship contract, and with Lalou Roucayrol as his mentor, Quentin has chosen the career of a skipper. So he pursued studies in technical sales at the Lycée de la Mer in Gujan-Mestras, while also following the Mini 6.50 Arkema 3 project and cutting his teeth in ocean racing on board this sailboat.

A very promising start under Lalou's kindly gaze

Passionate, hard-working and talented, Quentin is a fast learner. In 2014, for his first solo racing season on board a Mini 6.50, he battled it out to rank in the top 10 of the various events. In November 2017, the skipper secured 6th place in the overall ranking of his second solo transatlantic race, the Mini Transat.


In 2018, Quentin Vlamynck is working his way through the ranks by becoming boat captain of the Multi50 Arkema 1 and therefore “the right-hand man” of Lalou Roucayrol. Quentin sailed often alongside Lalou Roucayrol when ferrying the boat and also “false solo” training. The young man made the most of this experience to further improve his skills on a Multi50.


In 2019, Quentin is picked, by Arkema and Lalou Multi, to become the skipper of the future trimaran Arkema 4. At the ripe age of 27, the Biscarosse-born sailor is excited at the opportunity he has been given, and make good use of this year with a specific training program on the Multi50 Lalou Multi, coached by Lalou Roucayrol.



Lalou Roucayrol, passionate about the sea

Lalou RoucayrolLalou Roucayrol, the skipper of the Arkema Multi50 trimaran, is much more than a famous sailor. A specialist of ocean racing in multihull boats, he is a consummate racing sailor who surprises with his humanity and simplicity. He was born in the Médoc region, and the ocean is the playground in which he excels.


At odds with various fashions, Lalou successfully chalked up, over 30 years, one of the most impressive records in the multihull world. The skipper has stayed the same since he started: committed to developing his boats, while maintaining a certain kind of simplicity.


Bold and a sailing fanatic, Lalou is a genuine trailblazer in the world of ocean racing.


Lalou is also an entrepreneur who has succeeded in combining his passion for technology and performance with his love for the sea. The Lalou Multi structure which he has set up collaborates with some twenty people all committed to the collective success of the project.

His valuable experience also makes him an expert in materials for sailboats. Hence, Lalou collaborates closely with Arkema’s R&D hub to develop innovative technologies for the future trimaran Arkema 4.


But Lalou Multi goes well beyond sporting performance alone. Sailing is a concentrate of know-how and passion which Lalou has taken it upon himself to pass on to the younger generation, in particular Quentin Vlamynck. Lalou takes this coaching role particularly to heart by supporting Quentin during his training and the construction of Arkema 4.
