Which statement about logkeeping is true?

• A. Only Distress messages must be logged
• B. Distress, Urgency and Safety messages affecting the station's own ship must be logged
• C. All messages heard must be logged
• D. Logging is optional for MF-HF

Answer: (B)

Logkeeping focuses on recording safety-related communications that affect your vessel. The rule requires that distress, urgency, and safety messages that affect your own ship must be logged. This creates a reliable record of critical events, including when and on what frequency the message was heard, who sent it, and the nature of the message, which can be important for safety actions and any regulatory review. You don’t need to log every message you hear—only those that impact your vessel. And on MF-HF, this logging duty is mandatory for those safety-related messages that affect your ship.
