What is the purpose of a hurricane pile?

The correct answer identifies that a hurricane pile is designed as a single, unattached marker that serves to guide the range for aids to navigation (ATON). Hurricane piles are important in maritime navigation, especially for maintaining visibility for vessels during storm conditions. They are used to delineate safe channels and provide guidance to vessels, which is crucial during severe weather when visibility may be compromised.

In addition, hurricane piles are often positioned in a way that makes them more resilient to the forces of storms, ensuring they remain visible and functional even in challenging weather. This function is critical for navigators to make informed decisions regarding safe passage.

While the other options suggest different functions, they either do not encapsulate the primary purpose of hurricane piles or misunderstand their application in navigation. Understanding their unique role helps highlight the importance of effective navigation aids in maritime safety, particularly during adverse weather conditions.
