Use of AIS text messages between ships must not be used to avoid collisions
when time is critical. AIS systems are not required to have an audible alarm to
indicate the arrival of all text messages.
The use of AIS text messaging does not relieve the vessel of other requirements,
such as the Vessel Bridge-to-Bridge Radiotelephone regulations or of the
requirements to sound whistle signals and display lights or shapes in accordance
with the International or Inland Navigation Rules.
Usage During Emergencies
- With respect to using AIS safety related text messages in emergency situations, users
must be aware that they may not be received, recognized or acted upon as Global Maritime Distress Safety Systems
(GMDSS) messages would be by the Coast Guard, other competent authorities or maritime first responders. Thus
AIS must not be relied upon as the primary means for broadcasting distress or urgent communications, nor used in
lieu of GMDSS such as Digital Selective Calling radios which are designed to process distress messaging.
Nonetheless, AIS remains an effective means to augment GMDSS and provides the added benefit of being ‘seen’ (on
radar or chart displays), in addition to being ‘heard’ (via text messaging) by other AIS users within VHF radio range
(Ref: USCG Safety Alert 05-10).
