🔍 Key Concepts

• Hydrostatic release unit (HRU) function on liferaft arrangements • Difference between inflating a raft and freeing it from a sinking vessel • How SOLAS lifesaving appliances are designed to work if the crew cannot launch them manually

💭 Think About

• Think about what actually makes the raft fill with air versus what simply lets it float free of the ship. • Ask yourself: When a ship sinks and no one can reach the liferaft, what device is supposed to act automatically, and what exactly does it do? • Consider which option correctly describes what happens when water pressure increases as the ship goes under.

✅ Before You Answer

• Which choice talks about water pressure / sinking rather than just air or testing? • Which function is specifically tied to a predetermined depth under water? • Eliminate any option that confuses inflation mechanism with release mechanism.
