Q

What channel must all compulsory, non-GMDSS vessels monitor at all times in the open sea?

🔍 Key Concepts

• VHF distress, safety, and calling frequencies for non-GMDSS vessels • Difference between calling/distress channels and working channels • What channels are used for DSC (Digital Selective Calling) versus traditional voice watch

💭 Think About

• Which VHF channel has traditionally been used worldwide for distress, safety, and calling by voice for small and older vessels? • Among the options, which channel is associated with DSC/GMDSS rather than continuous voice monitoring on non-GMDSS vessels? • Think about which channels are typically used for ship-to-ship working traffic (tugs, pilots, workboats) instead of mandatory continuous watch.

✅ Before You Answer

• Identify which option is the international distress, safety, and calling voice channel for VHF • Confirm which channel number is primarily used for DSC (Digital Selective Calling) in the GMDSS system • Eliminate any channels you know are mainly used for intership working traffic rather than mandatory watchkeeping
