What is documented in a Security Record Book?

The Security Record Book serves as an essential tool for documenting all security-related activities and incidents that occur on a vessel. This includes details about security measures implemented during the voyage, records of security drills, threat assessments, suspicious activities observed, and any incidents that have involved the vessel's security. Keeping comprehensive records ensures accountability and aids in compliance with international and national security regulations. Additionally, it allows for the review and improvement of security protocols based on documented experiences.

The other options, while related to vessel operations, do not pertain to security documentation. Weather conditions, employee personal details, and maintenance logs are managed separately and serve different purposes outside the scope of security recording.
