What is the significance of the AIS Shiptype number?

A vessel's type can be deducted using the information contained in the AIS-transmitted messages that she is emitting. The vessel's crew or the accountable officer are responsible for correctly entering this piece of information to the vessel's AIS transponder.

AIS SHIPTYPE usually consists of two digits.

The first digit represents the general category of the subject vessel:

1 = Reserved
2 = Wing In Ground
3 = Special Category
4 = High-Speed Craft
5 = Special Category
6 = Passenger
7 = Cargo
8 = Tanker
9 = Other

In certain cases (e.g. Cargo Vessels, Tankers), the second digit provides additional information regarding the subject vessel's type of cargo:

1 = Major Hazard (Haz A)
2 = Hazard (Haz B)
3 = Minor Hazard (Haz C)
4 = Recognisable Hazard (Haz D)
