47°Nautik is a local public organization that brings together and manages several nautical centers in the Vannes area of Brittany, France. Rooted in the Golfe du Morbihan, it welcomes visitors year-round and in season at locations including Séné, Arradon, Baden and Sarzeau, with activities also based around Vannes. Its qualified instructors support beginners and experienced participants, from young children discovering the water to adults looking to develop their skills.

The organization offers sailing and watersports courses, private lessons, equipment rentals and guided outings. Activities include catamaran sailing, stand-up paddleboarding and kayaking, alongside traditional sailing trips aboard the Corbeau des Mers. Programs for younger children include the Jardin des Mers and Club Moussaillon, designed to introduce them to the marine environment in a safe setting. 47°Nautik also accommodates groups, holiday stays and sporting or language programs, and organizes company events focused on team cohesion and shared sailing experiences. Online reservations and a prepaid points card make it easier to book lessons and rent equipment.
