🔍 Key Concepts

• “Seelonce mayday” is an international radiotelephone phrase meaning enforced radio silence on the distress channel. • Only certain stations may transmit on the distress frequency once “Seelonce mayday” has been declared. • Vessels already proceeding to assist still have obligations, but must follow radiotelephone discipline.

💭 Think About

• Ask yourself: when radio silence is ordered on the distress frequency, are you supposed to add more traffic, or reduce transmissions? • Consider who is normally allowed to speak on the channel during a Mayday after “Seelonce mayday” is announced: is it every assisting vessel, or just specific controlling/distress stations? • If you are already heading toward the distress position, does “Seelonce mayday” cancel your assistance, or only control radio use?

✅ Before You Answer

• Verify what “Seelonce mayday” actually instructs all other stations to do on that working/distress channel. • Check which parties are permitted to transmit after this order: the distress vessel, the coast station/On-Scene Coordinator, or all assisting ships giving updates. • Confirm whether your duty to continue assisting is affected by a radio silence order, versus only how and when you may transmit.
