🔍 Key Concepts

• GMDSS manning requirements for compulsory vessels (how many licensed GMDSS operators are required, and is a maintainer always mandatory?) • Difference between a GMDSS Radio Operator and a GMDSS Radio Maintainer (who is allowed to do what to the equipment?) • Radio log requirements under GMDSS, especially for distress, urgency, and safety-of-life communications that you send or receive

💭 Think About

• First, decide which choices correctly describe the minimum number and types of radio-qualified personnel that MUST be on a compulsory GMDSS vessel at sea. • Then, think about what kind of work a GMDSS Radio Operator may do on the equipment and when a dedicated Maintainer (or shore-based/duplication options) comes into play. • Finally, recall what the rules say about logging distress/urgency/safety traffic: does it matter whether your vessel is directly involved, or just that the traffic is sent/received on your watch?

✅ Before You Answer

• Verify whether SOLAS/GMDSS actually says “at least two licensed GMDSS Radio Operators at all times while at sea” or whether the wording is slightly different. • Check if a compulsory vessel is required to carry a GMDSS Radio Maintainer, or if that’s only one of several permitted maintenance arrangements. • Confirm whether all distress/urgency/safety communications handled or monitored must be recorded in the radio log, or only those in which your vessel was directly involved.
