🔍 Key Concepts

• SART operating frequency and which marine radar band can detect it • Importance of a SART being properly mounted and elevated in a survival craft • Difference between 3‑cm (X‑band) and 10‑cm (S‑band) radar for search and rescue

💭 Think About

• Ask yourself: On what radar frequency band does a SART respond, and which ship’s radar band matches that? • Think about how the height and orientation of the SART in the lifeboat affects the radar’s ability to pick it up over the horizon or waves. • Compare the answer choices that combine both the correct radar band AND correct SART mounting – which option has both?.

✅ Before You Answer

• Verify which radar band (3‑cm/X‑band vs 10‑cm/S‑band) is designed to interact with SARTs under GMDSS. • Check that the SART in the chosen option is properly mounted (high and vertical) to maximize line‑of‑sight to the searching vessel’s radar. • Eliminate any option where either the radar band is wrong for SART detection OR the SART is mounted improperly.
