Navy inspectors are not authorized to inspect which type of vessel?

The reason cruise ships are not subject to inspection by Navy inspectors is related to the nature of their operations and the jurisdiction over such vessels. Cruise ships typically fall under the regulation and oversight of the U.S. Coast Guard and other maritime authorities dedicated to passenger safety and commercial operations. These agencies have specific guidelines and standards designed for the tourism and hospitality industry, which differ from those pertinent to Navy inspections focused on operational and military readiness.

On the other hand, commercial cargo ships, military vessels, and research vessels are more aligned with the responsibilities of Navy inspectors, particularly concerning compliance with sanitation and other safety regulations. Military vessels are under the direct jurisdiction of the Navy, while commercial cargo and research vessels can be inspected to ensure they meet relevant standards and practices concerning sanitation, environmental protection, and crew health, which are crucial for operational efficacy and public safety.
