Vagabond is rarely docked in Brest, his home port, but a model of the sailboat is now installed in the Polar Pavilion of Océanopolis, with video and pictures of her expeditions. The small red hull and her family crew are a simple mean to attract audiences wishing to learn more about scientific research in the polar region, and about the culture and way of life of Arctic people. Our privileged relationship with the Inuit, who appointed us Honorary Rangers in Northern Canada in 2012, allows us to help establishing fruitful exchanges between scientists and locals, and to work better together. It is today important for scientists to take account of ancestral knowledge to organize the field campaigns and to analyse the results.
