Discovered in Lost in the Swell, I contacted Erwan and we drank a beer at the Carroz d’Arraches. When he stepped in the bar in flip-flop I knew that I came to the right place.

This night I saw one of their films… And I wasn’t sure that I cam to the right place anymore when I heard Xavier De Le Rue saying that in the boat, the temperature wasn’t higher than 5°… But whatever , this need to confront ourself to the environment and the will to raise awareness among peoples through committed documentaries makes you easily forget all of these details. And French Brittany doesn’t seems as much worst as the Greenland it isn’t ?

Between see and mountain I can’t choose between them… Passionate by these milieux, I remotely followed Maewan’s adventures until the day I met Marion and Erwan during an event.

I was very touched by their project, their commitement, their values, and their bravery !

So, I try my best in order to make my contribution to bring their actions and their commitement to light in my reports in order to raise awareness among a larger amount of people.

Ah ! Finally ! It’s been 7 years I’ve been waiting to have seasisckness ! And that’s done with the French Brittany-Ireland travel. Finally a trip with Erwan with whom we did some RocTrip together when he was a member of Petzl.
I’m really glad I came aboard Maewan, this brand new mythical boat. Mythical because of its background, its sturdiness, its famous guests, and above all of that, its mythical kind, friendly, welcoming and generous crew ! A true family for sure ! Erwan, Marion and now Hoël, the best little pirate.
During this trip, climbing the astonishing Inis Mór, one the Aran Islands in Ireland, obviously makes me want to sail again with them to discover new cliffs and spend great time with the Wawan Family in their future travels during this crazy project !

Maewan, a boat and its captain, Erwan. Maewan, an acquaintance and a companion. Maewan welcomed me in their adventure in the autumn of 2016, in the Bering Sea. Since then, Maewan has become part of my daily vocabulary. An extraordinary adventure with no boundaries, with fair human values, Maewan is one of the encounters that have marked my life’s evolution. Being on board Maewan is a true honour. An inextensible cocoon where sweat rhymes with warmth. Sharing with mooring.

Kite surfing, highline, climbing, sailing. Alaska, Shishmaref, Nome, Bering Sea, French Polynesia, The Marquesas Islands, Tahiti, Makatea, Rapa, Pitcairn Islands, Easter Island. The list is long and the memories even longer. The only downside of the story is that I still haven’t managed to get my hands on the stash of Chartreuse and Nutella.

I got to know Erwan when I worked for Petzl (2001 to 2017). With Laurent Lafouche, we formed a “magic ” trio to bring out the best in communication and events: not only films, but alsoadvertisement, websites, and events, including the famous PetzlRocTrips. We have worked together for 10 years, always with great energy and creativity. I left the Petzl company shortly after Erwan, and it was a pleasure to be able to join the Maewan association, which represents my values for the environment, education, and sport.

Stef and I set off to join Erwan as he arrived in the Solomon Islands after a month of sailing solo. Neither Stef nor I were sailors, it was a bit hectic, and very soon we were unable to leave the deck. We waited wisely for Erwan to come and bring us some food, it was impossible to go down into the hold, a great lesson in humility! We still survived and shared a magical week in the village of Utupua, sailed in Vanuatu, a great life experience aboard Maewan.

Greenland, Kuriles, New Zealand, French Polynesia, to think I was afraid of “Jaws” as a child, but now I’m much better. However I can no longer drink Vodka since “Maewan aux Kuriles” (fortunately Chartreuse is one of the boat’s sponsors). Over the years Maewan has become a bit of a second home to me. My favourite sleeper is the one close to the engine, it reminds me (from a distance…) of my cat’s purr.

I’m proud to have launched the double-cabestantrend, to eradicate the epidemic of drifting(dingy or zodiac) and to be allowed to charge its batteries on board (even though it was after the captain).
- Distinguishing featureA hyper-active soul, Béber is often the one who makes the traces, sees through the round trip ,to get the best shots of the athletes who embark Maewan, and that's something! Curious (too much?), jack-of-all-trades (too much?), in any case impossible to sleep in, and therefore finds it difficult to stay up until 6am during a night out, however he is capable of emptying apacket freeze-dried fruit in a few seconds. Marion and Erwan have found the solution: special lunchboxes for Béber when he is on board.

TF1 journalist since 2004, in charge of mostly committed articles: nature, adventure, interesting stories, sport, tourism… Erwan and I met during Maewan’s first break in polar regions. We were in the East of Iceland to share life on the boat and film some wonderful moments, including a fabulous climb on an ice fall in a remote fjord during nightfall.

One of our most beautiful reports which won us the award for the best report according to sports journalists of the year 2016. Forever engraved…

It was a truly incredible experience. I am forever grateful, to have been given the opportunity to work within this incredible community through the Makatea project put into place by Maewan. They managed to bring together an amazing team of 15 professionals from all over the world, who all share the same passion.

World class atheletes, photographers, film producers, journalists, educators, and the magic did its thing. Without a doubt one of the best and most productive trips I have ever done. An faultless organisation, whether it was transport, accommodation, food, but also the daily organisation of work for everyone.

My favourite memory is everybody’s joint effort towards a common goal: Makatea’s inhabitants, TheMaewan crew, the Acropol society, and the French Polynesian tourists during the inauguration event. We all felt connected, whether it was at the campsite, during the sports discovery events, or during the evening meals. It was one of the best experiences of all time, and I hope to be able to join them again sometime! I miss you all!

Great vibes your way…

Vous me manquez tous! Great vibes your way……

16 years ago, I met Erwan at the foot of the Champagny-En-Vanoise ice fall. Six months later, we got to know each other better on a chalk cliff in Dover, slightly, where, in the presence of Sam Beaugey, he was testing dry-tooling for a report in the magazine Equipe. At the time, he already had the desire to go to sea… During the Roc Trips he organized for Petzl, including the memorable Chinese edition that earned him the nickname of xiexie (pronounced cheeky) Wawan, I learned to understand his phlegmatic humour that hides an incredible energy and ability to bring people together.

His projects are crazy. He probably is a little crazy. Still, I followed him to Alaska for an unforgettable crossing of the Bering Strait in 2016, then back to the Marquesas two years later. The third time at Makatea in June 2019 for this wonderful project to bring theisland back to life through rock climbing.The Makatea episode sums up “MaErwan”, which has become an extension of his sailboat: adventure at the end of the world, rock, water, solidarity and a great sense of commitment.
- Distinguishing featureCompulsive writer. Never leaves her small spiral notebook and ballpoint pen to ask millions of questions to anyone in her field of vision. Repeats often, not because she's deaf (that's for later), but to make sure she doesn't write nonsense. If there's an easy cliff lying around, she won't say no. If there's a valley that's not too steep for skiing or snowboarding, she always joins in. She can get on any boat, because she never throws up. That's good, because apart from cooking and eating, she doesn't know how to do much else on the water.

As an old friend of Erwan’s I was involved in the early stages of this project both in a literal and more figurative sense. The departure from Britanny and the extreme winter sailing into Iceland and Greenland were a solid beginning where my skills as an amateur sailor were put to the test! Since then I have followed with passion but from a distance, in the warmth of my sofa in the Alps, Maewan’s extraordinary adventures, the evolution of the project into an association. Today, it is with great joy and a emotion that I join the captain and his crew in the warm and isolated waters of Polynesia.
