🔍 Key Concepts

• Sheath-screw davit construction – how the screw travels inside the sheath when cranking out • Purpose of the maximum angle marking on davits for lifeboat launching • What can happen if mechanical travel limits are exceeded on screw-type gear

💭 Think About

• Visualize the screw inside the sheath: if you keep turning it past its marked limit, what mechanical problem could occur with the screw and its support? • Ask yourself why the manufacturer would mark the angle rather than just warn about chafe or positioning – what part of the davit’s mechanism is most at risk when over‑extended? • Consider which option describes a direct mechanical consequence to the screw/sheath system itself, not just a secondary effect on the boat or falls.

✅ Before You Answer

• Focus on what a sheath-screw actually is: a threaded screw running inside a fixed sleeve (sheath). What happens if the screw moves too far? • Separate effects on mechanism (screw and sheath) vs. effects on boat position or falls – which is the primary design concern of the angle marking? • Eliminate choices that could occur with any davit type and look for the one that is specific to a screw running in a sheath.
