Which part of the CFR primarily concerns maritime security regulations?

The correct answer encompasses all aspects of maritime security regulations found within the Code of Federal Regulations (CFR), specifically 33 CFR parts 101, 104, and 105. Each of these parts plays a distinct role in establishing security protocols and guidelines to safeguard maritime interests.

Part 101 outlines the general provisions related to maritime security, including definitions and applicability of the regulations. This foundational part sets the stage for the subsequent, more specific requirements laid out in the following sections.

Part 104 focuses on the security measures applicable to vessels, detailing the responsibilities of vessel owners and operators in implementing security measures to protect against threats and vulnerabilities. This part emphasizes the creation of security plans, training for crew members, and regular drills to ensure preparedness.

Part 105 addresses the requirements for facility security, specifying what facilities must do to ensure they meet security standards that protect against unauthorized access and to combat potential threats. It outlines security assessments, plans, and the roles of designated security personnel.

By understanding that all three parts work together to create a comprehensive framework for maritime security, it becomes clear why the response indicating that all of them are relevant is correct. Each part complements the others, ensuring cohesive security regulations across both vessels and facilities involved in maritime operations.
