Leisure boat users may be sailing in the same waters as large commercial vessels and will need to have their position and information noted to avoid any collision. This is what AIS (Automatic Identification System) does.  ...

The AIS system is using the MMSI, not the IMO number, to identify a vessel. The IMO number is part of the static AIS information provided by the vessel crew and can be transmitted additionally.
