"The office refers to the Inland Navigation Ordinance - Article 16., Link opens in a new window There it says it again in black and white: vessels must be registered unless they are shorter than 2.50 metres. And there are further exceptions: Beach boats or paddle boats do not have to be registered either." https://www.srf.ch/sendungen/kassensturz-espresso/gummiboote-ueber-2-50-meter-muessen-angemeldet-werden
