Which of the following is an authorized vessel for enforcement actions?

The correct answer indicates that a Coast Guard vessel is an authorized platform for enforcement actions. Coast Guard vessels are specifically equipped, staffed, and trained to perform a variety of law enforcement duties, including search and rescue, fisheries enforcement, and drug interdiction. They operate under authority granted by federal law and are equipped with the necessary tools, training, and support to conduct such enforcement actions effectively.

These vessels also have specific legal authority under maritime law allowing them to board and inspect vessels, enforce regulations, and carry out other law enforcement activities. Their design, capabilities, and legal empowerment make them a critical asset in upholding maritime law and ensuring safety and security in U.S. waters.

The other choices do not hold the same level of authority or capability. Private yachts and commercial fishing boats do not possess the legal authority to enforce maritime laws on other vessels. Military aircraft, while they may have certain roles in maritime operations, are not primarily designated for routine enforcement actions on the water, making them unsuitable for the context of the question regarding authorized vessels for enforcement actions.
