Recognising Distress and Preparing the Alert
Deciding when grave and imminent danger justifies distress priority and preparing identity, position, nature and assistance information.
How to prepare for the Marine Radio SRC
Build from station licensing and radio controls to disciplined voice and DSC traffic, then rehearse distress, urgency, safety, false-alert and GMDSS decisions on training equipment.
Core concepts
Concept 1
Distress priority is reserved for grave and imminent danger to a vessel or person when immediate assistance is required.
Exam cue: State the danger, immediacy and assistance required before choosing priority.
Concept 2
Before alerting, obtain the best available position and time, confirm vessel identity and decide whether the nature of distress can be selected without delaying transmission.
Exam cue: Use current GNSS position but be ready to enter position and time manually if the set lacks valid data.
Concept 3
The operator must balance preparation with speed: send the alert promptly, then supply fuller information by voice.
Exam cue: Write a short Mayday information sequence when circumstances permit.
Risk pitfalls and guardrails
Delaying a real distress alert while searching for perfect information.
Guardrail: Do not present the 601-item authoring target as an official RYA paper and do not treat static study as a substitute for the recognised written and practical examination.
Using distress priority for a routine breakdown without grave and imminent danger.
Guardrail: Do not present the 601-item authoring target as an official RYA paper and do not treat static study as a substitute for the recognised written and practical examination.
Assuming the displayed position is current without checking time and GNSS status.
Guardrail: Do not present the 601-item authoring target as an official RYA paper and do not treat static study as a substitute for the recognised written and practical examination.
Memory anchors
Grave + Imminent
Both danger and need for immediate assistance define distress.
Identity
Know vessel name, call sign and MMSI.
Position
Use the best current position with an explicit reference and time.
Nature
Select or state fire, flooding, collision, grounding, sinking or other danger.
Alert Promptly
Do not let missing detail delay the first effective request for help.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A yacht is on fire, flames are spreading and the crew may have to abandon immediately. Which priority applies?
A yacht's engine fails in calm open water with sails available and no immediate hazard. Does that alone justify Mayday?
