Reference Answer
A comprehensive description of the key safety and operational components of a gravity lifeboat davit is as follows:

**1. Purpose:**
The primary purpose of the centrifugal brake is to automatically control the speed of descent of the lifeboat when it is being lowered under gravity. It ensures the lowering speed remains within safe limits as prescribed by SOLAS, preventing an excessively fast and dangerous descent, irrespective of the number of persons in the lifeboat.
