Question 1486Navigation General

The correct answer is D) the type of credential he/she holds and its serial number. The owner or Master of a towing vessel operating within a Vessel Traffic Service (VTS) area is required to report information such as shortage of personnel, lack of charts/publications, vessel maneuverability characteristics, and any malfunctions of critical onboard equipment. However, the type of credential held and its serial number is not required to be reported to the VTS, as this information is not directly relevant to the VTS's role in managing vessel traffic and navigational safety. The other answer choices represent information that the VTS needs to be aware of to properly monitor and coordinate vessel movements within its area of responsibility.
