70% to pass

If you are the Master of a towing vessel whose only working radar no longer functions, what must you do?

A Anchor the vessel until it is repaired.
B Moor the vessel until it is repaired.
C Notify the Captain of the Port (COTP) if you cannot repair it within 96 hours.
D Notify the Officer in Charge of Marine Inspection (OCMI) if you cannot repair it within 48 hours.
AI Explanation

The correct answer is C) Notify the Captain of the Port (COTP) if you cannot repair it within 96 hours. This is the correct answer because according to U.S. Coast Guard regulations, if a towing vessel's only working radar fails, the Master must notify the COTP if they cannot repair it within 96 hours. This requirement is in place to ensure the vessel can safely operate without a functioning radar. The other options are incorrect because anchoring or mooring the vessel is not required, and notifying the Officer in Charge of Marine Inspection (OCMI) within 48 hours is not the correct notification procedure in this situation.
