Which data is transmitted by the AIS device?

Data transmitted by the Inland AIS station must always be up to date, according to article 4.07 (2) of the Rhine Police Regulations. It is the boatmaster’s responsibility to ensure that all data transmitted by the AIS station matches the vessel’s or convoy’s current data.

Vessels fitted with Inland AIS device transmit and receive information on an automatic and periodical basis from other ships equipped with AIS device. The main information regards the vessel and its current nautical data:

Identity of the vessel
Its exact position
Its course and speed
Other ship-specific data

However some data must be entered manually by the boatmaster. The most prominent of which are :

navigational status of the vessel (e.g. under way, moored or at anchor)
Type of vessel / convoy
Overall length and beam of the vessel / convoy
