Between 140 and 170 boats will be engaged to transport 10,000 athletes during the opening ceremony of the 2024 Olympic Games in Paris, an unprecedented nautical parade on the Seine, said Thursday March 30 the prefect of the region Marc Guillaume. ” It is a huge challenge which will be to send 140 to 170 boats from the east of Paris, on the edge of Ivry, and to get them from the Pont d’Austerlitz to the Trocadéro “, 6 km further west, indicated the representative of the State during a point before the regional council of Ile-de-France. Between the desire to offer the world an exceptional event and the imperative of security, the preparation of the parade proves to be a headache for the organizers. Like the number of spectators (from 400,000 to 600,000), the number of boats is also the subject of discussion.
