Semaine du soir de Versoix

The Semaine du Soir de Versoix is a convivial and festive regatta week that takes place every year in Port Choiseul (Versoix) near Geneva. It is organised by the Yachting Club du CERN and the Club Nautique de Versoix. The event took place between 20 and 24 June 2022!

This year, the Semaine du Soir de Versoix was very happy to be part of the official competitions of the Petit Lac Championship.

After two years of restrictions, events and social activities could again take place after the regattas, see the programme.

The event was a great success despite the not always favourable weather conditions.

A huge thank you to all the participants, the bands, the Versoix Nautical Club restaurant, the foodtrucks and all the volunteers without whom the event could not have taken place!

We look forward to seeing you at the Semaine du Soir 2023!

The final results of the regatta have been published and can be viewed here or directly on the Manage2Sail website.
