Before you start
Gather the appropriate supplies and review the specific equipment manual.
- VHF radio manual
- GPS position source
- Crew emergency card
Step-by-step instructions
Check equipment readiness
Confirm the radio works, the antenna is serviceable and DSC identity and positioning are configured where required.
Prepare emergency details
Keep vessel name, call sign or MMSI, position format, people aboard and emergency equipment details handy.
Learn the distress functions
Review the radio manufacturer guidance for DSC alerts and voice distress on the correct local channels.
Practice without transmitting a real distress
Use only authorized training or test procedures; rehearse verbally with crew.
Assign roles
Plan who calls, who handles steering and who prepares lifesaving gear while awaiting instructions.
Safety note
Do not send a false DSC distress alert or MAYDAY call as a drill. In a genuine emergency, follow official radio procedures and local rescue direction.
Key takeaway
A rehearsed emergency message saves precious time when people are under stress.
