USCG Exam Practice · GMDSS and VHF distress procedures
When making a voice MAYDAY call on VHF, how many times must the vessel's name be spoken in the initial call-up?
- AOnce
- BTwice
- CThree times✓ correct
- DFour times
Why C is correct
Both 46 CFR §28.265(d)(4)(iv) and 46 CFR §184.510(a)(4) specify that the vessel's name is stated three times in the initial call-up. This repetition ensures the name is clearly received even in poor radio conditions.
