🔍 Key Concepts

• Human survival physiology in liferafts and survival craft • Effects of salt intake and dehydration on the body • Standard guidance from survival manuals and SOLAS/USCG liferaft instructions about drinking water

💭 Think About

• Think about what drinking seawater does to your body’s hydration: does it add usable water or increase dehydration? • Consider whether any of these options (rainwater, very small amounts, mixing with fresh water) truly remove the danger from the salt content. • Ask yourself: in real survival training, what are you told about drinking seawater under any circumstance?

✅ Before You Answer

• Verify what standard survival at sea manuals and liferaft instructions say about drinking seawater. • Consider whether diluting seawater with a small amount of fresh water makes it safe or still dangerous. • Check which option best matches conservative safety-first guidance taught on USCG/merchant mariner exams.
