Ocean Hackathon® is 48 hours non-stop to develop a prototype in a team and to think about its use, using various digital data related to the sea. A call for challenges is launched a few months before the event to identify projects on which the teams will position themselves in each of the participating cities. At the end of the weekend, one team will be elected to take part in the international pitching competition at the end of 2021 in Brest and may win one of the prizes offered by our Ambassadors.
