What must be fitted on life boat davits to prevent over stressing of falls?

The requirement for safety devices on lifeboat davits is crucial to ensure operational integrity and safety when launching or retrieving lifeboats. Safety devices are specifically designed to limit the load on the falls and prevent over stressing them, which can occur during abnormal conditions such as rough seas or improper handling.

These devices often include mechanisms such as overload indicators or automatic release systems that activate when the load exceeds safe limits. By incorporating such safety measures, the risk of equipment failure or accidents can be significantly reduced, thereby enhancing the safety of the crew and passengers during emergency evacuations.

In contrast, emergency beacons, buoyancy aids, and rescue nets serve different purposes related to survival and rescue operations rather than directly addressing the structural integrity and operational safety of lifeboat davits. While these items are essential for other aspects of safety and rescue preparedness, they do not provide the necessary protection against the risks associated with overloading the falls on lifeboat davits.
