Which resource is used to verify the status of arriving vessels?

• A. MISLE (SANS) and the Duty Vetter
• B. AIS alone
• C. NAVTEX
• D. Local harbor reports

Answer: (A)

Verifying the status of arriving vessels relies on an authoritative, centralized record and a trusted check by a supervisor. MISLE is the Coast Guard’s central system for tracking vessel compliance, inspections, and port status, and the SANS component provides the arrival-related data you need. The Duty Vetter is the designated person who reviews that data and confirms the actual status before proceeding. This combination gives you an official, validated status for each vessel.

Relying on AIS alone isn’t sufficient because AIS only shows where a ship is or where it claims to be, and it can be turned off or spoofed. NAVTEX delivers weather and navigational warnings, not vessel clearance. Local harbor reports may be useful but aren’t authoritative or always up to date.
