🔍 Key Concepts

• Manufacturer’s maintenance and safety requirements for davits and launching appliances • Purpose and function of a pivot pin at the base of a sheath‑screw boom davit • What must be done to critical moving parts to ensure safe operation and reliability over time

💭 Think About

• Think about what the pivot pin actually does during launching and recovering the boat. Is it a moving part, a locking part, or a temporary fitting? • Which choice describes a realistic, routine safety practice that prevents wear, corrosion, or seizure of a critical joint? • Ask yourself which option sounds impractical or unsafe if applied over the full life of the vessel’s davits.

✅ Before You Answer

• Identify whether the pivot pin is a permanent structural part or something you would insert/remove every time you use the davit. • Consider which option aligns with normal inspection and maintenance routines rather than extreme or unlikely procedures. • Eliminate any answer that would create unnecessary risk of failure or be clearly unrealistic for regular shipboard operations.
