What is the primary purpose of a stability booklet for a vessel?

The primary purpose of a stability booklet is to provide detailed stability information for safe operation of the vessel. This document contains critical data that helps the crew understand how the vessel behaves in different loading conditions and sea states. It includes information such as the center of gravity, metacentric height, and stability curves, which are essential for ensuring that the vessel remains upright and seaworthy during its operations.

Having this information readily available is vital for making informed decisions about loading, ballast management, and operational practices. The stability booklet plays a crucial role in safety by guiding the crew in maintaining proper stability criteria to prevent capsizing or other hazardous situations while at sea. Understanding these parameters is essential for the crew to safeguard not only the vessel but also the lives of those on board.
