- vessels of 300 gross tonnage and upwards engaged on international voyages
- vessels of 500 gross tonnage and upwards not engaged on international voyages
- passenger ships irrespective of size.
The AIS referred to in the SOLAS convention is often termed ‘AIS Class A’.
AIS class B
AIS Class B is intended for use on non-SOLAS vessels. These can include domestic commercial vessels and pleasure craft.
In regards to the voyage information AIS class A vessels reports Destination and ETA more as compared to AIS Class B vessels. which is normal when looking at global AIS. class B vessels and small class A vessels tend not to report voyage data.
