You are piloting a vessel, which is required to have a radiotelephone, on the navigable waters of the United States. Choose the best answer that states the requirement(s) of the regulations?

Correct Answer: Option D — All of the above

The operator must hold at least a Restricted Radiotelephone Operator Permit to ensure competent operation of the equipment.
