About the trip

We have sailed 16000km during 6 months from Brest until the Costa Rica, passing through Canary Islands, Mexico, Bahamas, Panama, Columbia in the pacific side.

With Mecton, our sailing boat, we studied an itinerary depending on sharks migration and weather conditions. We meet 13 species of sharks and among them, bull sharks, tiger, great hammerhead and longimanus.

  1. Marina du château, Brest

    The departure

    We left Brest begining of January in front of our families and friends. It was very emotional after so much preparation before. Before that, 3 weeks of stressfull period waiting for the good window to face the Biscay Bay in winter.

    It was cold, we were hungry but we finally arrived after ç days navigated. Not to bad, when you know, only one of us really knew how to navigate.

  2. Tenerife (Spain)

    Beginning of the transat

    Here we go for 20 days alone in our sailing boat ! 20 easy days at the end, the weather was good and the automatic pilote was working well…

    We started to created habits : we fish mahi mahi, when there is no wind we go free-diving in a very clear water, we swin with dolphins when they let us play with them, we are surfing with Mecton when there is big wave…

    We just enjoy between friends !

  3. Playa del Carmen (Mexico)

    Arrival in Mexico

    Arrived after 2 months travelling, we win our bet, and bull sharks are still hanging around.

    We rapidly go on te water, the spot is just 300 meters away from the shore. And we start to dive with the first huge sharks of the trip.

    We finish our trip in Playa by free-diving with bull sharks at 25 meters deep. Without the bubbles, they are less afraid and come closer. Before that we were training in the cenote

  4. Bimini Island (Bahamas)

    Arrival in the Bahamas

    Probably one of the best place in the world to dive with sharks. Whether in Bimini, Tiger Beach or Cat Island, we have seen many sharks. A heaven to us !!

    Being autonomous in our sailing boat, we can dive differently, not like simple tourists. We don’t feed them, so we have to be patient but it worse it, They finally came at us very close.

  5. Colon (Panama)

    The Panama Canal

    How to pass from an ocean to another in 10 hours.

    It’s an incredible moment, being surrounded by huge taker going up and down to cross the country.

    Now it’s raining a lot and the water is less clear but full of life.

  6. Malpelo Island (Colombia)

    Arrival in Malpelo

    You have to deserve Malpelo ! We broke the boat, we faced bad weather conditions, and we had to deal with a lot of administrative paper.

    But it totally worse it ! It was one of the best part of the trip, school of shark are all around the boat.

    Thanks to Sandra Bessudo and all the Foundation Malpelo.

  7. San José (Costa Rica)

    Back in France

    We have dived in Costa Rica, we saw a bull shark in Bat Island and lot of white tips sharks in Isla del Cano.

    Everything come to an end and we have now to go back in France. Saddly we couldn’t go to Guadalupe.

    We let Mecton in a marina for a while, we will come back in 2020 to finaly dive with the great white shark.

Science

All along the trip, we tried to help scientifics. During the transat, we collected plankton, and we sent the sample so that scientifics in Concarneau could study them. We also took pictures of all the cetaceans with GPS position to study their migration.

We are very proud of our passage in Malpelo. We helped the Malpelo Foundation to study hammerhead shark. We were free diving and collecting DNA sample of hammerhead, recover datas from underwater receptor, and we installed cameras around Malpelo to study the population of pelagic around the island.

Food autonomy

We left Brest hoping that we could survive in our boat in order to dive in remote island. We cultivated seaweeds, germinated seeds, mushrooms, we were breeding crikets, and we were thinking that we could fish a lot. Unfortunatly when the fishing wasn’t good, or forbidden in natural park, we had to eat pasta and rice… For the water we had a watermaker onboard.

Energy

For the electricity, we had five solar panels and one wind turbine. We were totally autonomous even if we had a huge consumption (camputeur, underwater light, cameras…)

We could fill our diving tank with the small compressor we had, it was running with fuel so we had to stock some liters and as well fill up the diesel tank when we were navigate in area without wind (like in Colombia)

About the sharks

We wanted to dive with the five species of shark supposed most dangerous for Human Being. At the end we could see only four of this species. We will go back in 2020 to see the great white shark.

In total, we dived with 13 differents species of sharks, and among them bull shark, tiger shark, great hammerhead and longimanus. We have observed different behaviour depending on where we dived and with what kind of species.

Tiger beach and Malpelo were the best spots. Thoses places are protected area where sharks cannot be fished and we hope it’s going to stay like that.
