Passage in front of Bonifacio at night, we enjoy a magnificent fireworks display. The night is magnificent, and the crew is struggling to go to bed despite the night shifts which continue. In the morning, a few clouds, but nothing frightening according to the weather forecasts. We pick up the latest weather report announcing heavy storms on the French coast, right towards Marseille, where we are heading. Well it's not ideal, but we should avoid them by changing the cap : we go in a straight line on the continent, straight on Borme-les-Mimosas. Several net samples are taken again. In the afternoon, the wind picks up and Le Labo is well carried by a fresh breeze… well, it's coming from that cloud over there it seems… and it's getting closer quickly no ? ... In a few minutes, the light breeze turns into a real storm. Marie and Sarah throw themselves on the deck to lower the mainsail, Christophe at the helm, Jean-Luc distributes the survival vests and everyone clings : The Lab is caught in a big thunderstorm. The hours pass and the storms follow one another, then all of a sudden everything becomes calm again, the sky is revealed, there is no longer a sound. We find our summer constellations, and sleep.
