Module 9 - GMDSS & Safety Equipment

SART, AIS, And Locating

Search and Rescue Transponders and AIS locating devices help rescuers find a survival craft or casualty after the alert has been raised. They are locating aids, not full two-way distress communication.

AIS can also improve awareness, but it does not remove lookout or COLREG responsibilities and it is not carried by every target.

Key points

  • SART/AIS SART help with final location.
  • AIS is useful but incomplete.
  • Do not rely on one electronic layer.
  • Crew should know where equipment is and how it is deployed.
