What document is issued by a classification society to assign Load Lines?

A classification society issues a Freeboard Assignment to determine and assign load lines on vessels. The Freeboard Assignment provides necessary standards for the vessel's structural integrity and safety, which helps in defining how much cargo a ship can safely carry based on its design and construction characteristics. This document specifies the maximum permissible immersion levels for different types of cargo and environmental conditions, ensuring that the vessel maintains adequate safety and stability at sea.

In contrast, the other options serve different purposes related to vessel safety and operational regulations: an Equipment Record details the machinery and equipment onboard, a Cargo Securing Manual outlines best practices for securing cargo to prevent shifts during transit, and a Certificate of Fitness certifies that the vessel is suitable for specific types of cargo, typically pertaining to safety and health regulations. While all these documents contribute to the overall safety and operation of a vessel, it is the Freeboard Assignment that specifically pertains to the assignment of load lines.
