GMDSS-ROC-L3.1

Search and rescue communications

GMDSS-ROC-M3 · SAR communications and certification · GMDSS-ROC-M3-A Radio work during search and rescue, and where the ROC is and is not enough on yachts.

Once an alert has gone out, the radio work changes: a **rescue coordination centre** takes control, ships and aircraft talk on **on-scene channels**, and everyone else keeps quiet. An ROC holder may be on the yacht in distress, a yacht assisting, or both.
