How to navigate? The rules of inland navigation in Europe
European Code for inland waterways (CEVNI) contains a set of harmonized rules for inland navigation providing model rules for national and international legislation and relate to rules of the road, signalling on inland waterways, night and day time marking of vessels as well as waterway signs and marking.
The Code is complemented by the regional and national special requirements, which are tailored to the specific navigational conditions of a particular waterway.
Standardized UNECE Vocabulary for Radio-Connections in Inland Navigation (Resolution No. 35) contains standardized phrases in Dutch, English, French, German and Russian recommended for usage by crew members and shore based personnel during radio communications in order to avoid language barriers.
