Q

Equipment for radiotelephony use in survival craft stations under GMDSS must have what characteristics?

🔍 Key Concepts

• GMDSS survival craft VHF radiotelephone requirements under SOLAS/ITU • Difference between a ship’s main VHF radiotelephone and a survival craft portable VHF • Purpose of Channel 16, Channel 13, and Channel 70 (DSC) in GMDSS

💭 Think About

• Ask yourself: Would a survival craft radio realistically be required to have DSC (Channel 70)**, or is DSC mainly for fixed installations on the ship? • Think about why survival craft equipment needs to be watertight and what power level makes sense for a battery-powered unit used in a raft or boat. • Which VHF channels are most critical for distress and on-scene coordination from a liferaft, and which channels are more for ship-to-ship navigation safety or digital calling?

✅ Before You Answer

• Verify which channels a GMDSS survival craft handheld VHF is specifically required to have (compare Ch-16 vs Ch-13 vs Ch-70). • Check whether survival craft VHF sets are intended to be portable with an integral antenna or high‑power units with 25W output and DSC like the ship’s main set. • Confirm that survival craft radios must be watertight and have at least a certain minimum RF power output suitable for short-range distress and safety communications.
