🔍 Key Concepts

• On-load vs. off-load release mechanisms for lifeboats and rescue boats • Purpose of the safety pin in a survival craft release hook • Sequence of actions required before the boat is waterborne

💭 Think About

• Think about what the safety pin is preventing you from doing. After it is removed, what control can now be operated? • In this question, the craft is still suspended from the cable above the water. Is this considered an on-load or off-load condition, and how does that affect which extra motions are needed? • Which combination of actions sounds like a complete, deliberate motion needed to avoid accidental release, rather than something that could be done too easily by mistake?

✅ Before You Answer

• Verify which part actually trips the hook to let the boat off the falls (the cable). • Consider which extra control (ratchet bar or retainer) is associated with controlling the winch versus arming the release hook. • Ask yourself: in real equipment, what secondary device must be overcome to prevent accidental movement of the release handle while suspended?
