How long must GMDSS Radio Logs be retained...

🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) log requirements under SOLAS and 47 CFR/46 CFR radio regulations • The purpose of keeping radio logs (distress, urgency, safety, routine traffic) for possible investigations or inspections • Difference between very short-term records (like daily checks) and official log retention periods

💭 Think About

• Think about why authorities might need to review GMDSS radio logs long after a voyage—what kinds of incidents or investigations could occur? • Compare the answer choices to typical audit or inspection cycles: which period seems long enough for flag state and port state control to look back at your records? • Consider whether GMDSS logs are treated more like "temporary checklists" or like official records that must cover many months of operations.

✅ Before You Answer

• Check SOLAS Chapter IV (Radiocommunications) for any minimum log retention period mentioned for radio records. • Verify in U.S. regulations (47 CFR or 46 CFR) what they say about how long a GMDSS radio log must be kept onboard in its original form. • Make sure you distinguish between how often logs are made or signed (daily/weekly) and how long they must be kept onboard before they can be landed or archived.
