What should a mariner always be cautious of when navigating by buoys?

When navigating by buoys, it is crucial for a mariner to be particularly aware of environmental changes that could affect buoy positions or visibility. Buoys are typically anchored to specific locations; however, shifting tides, currents, and winds can displace them. Additionally, factors such as poor visibility due to fog or heavy rain can make buoys harder to see, increasing the risk of navigating incorrectly.

Understanding that the environmental context can change rapidly emphasizes the importance of assessing the situation continually while at sea. Maintaining awareness of these conditions can prevent potential hazards and ensure safe navigation. While considerations like weather, interactions with other vessels, and buoy types are also important, the dynamic nature of the environment adds a layer of complexity to navigating by buoys, making this awareness paramount.
