🔍 Key Concepts

• GMDSS documentation requirements for sea areas A1–A4 • The role of station logs under GMDSS and SOLAS • Why ships need up‑to‑date regulatory and planning documents when operating internationally

💭 Think About

• Ask yourself which of these items would be routinely checked during a Port State Control or Flag State inspection on a GMDSS‑equipped vessel. • Consider whether GMDSS focuses only on equipment, or also on records, regulations, and information needed to use that equipment correctly. • Think about which of the listed documents directly support the safe and compliant operation of your radios and distress systems in all sea areas.

✅ Before You Answer

• Verify in SOLAS Chapter IV what documents and records must be carried for radio communications. • Check whether FCC rules (47 CFR Part 80) are required to be physically carried onboard for vessels subject to GMDSS on international voyages. • Confirm if the IMO master plan of shore‑based facilities is intended primarily for administrations or if ships also need an onboard copy.
