Where are a ship's overall dimensions described?

A ship's overall dimensions are typically described in the Ship's Information Book (SIB). This document serves as a comprehensive reference for a ship, detailing critical information such as its length, beam, draft, and other key dimensions that are vital for operations, navigation, and regulatory compliance.

The importance of this information lies in its influence on various aspects of maritime operations, including stability calculations, loading and unloading procedures, and ensuring that the vessel complies with port and navigation regulations. The SIB is also useful for crew members and engineers when assessing the ship's capabilities and limitations in various environments.

While other documents like the Safety Data Sheet, Maintenance Manual, and Engineering Log contain important information, they do not specifically compile the overall dimensional data of the ship. The Safety Data Sheet is primarily focused on chemical safety information, the Maintenance Manual addresses upkeep and repairs, and the Engineering Log records ongoing technical data and operational specifics rather than overall dimensions.
