What does the term "buoy deterioration" refer to in IALA navigational practice?

The term "buoy deterioration" in IALA navigational practice specifically refers to the wear and tear on buoys that can compromise their visibility and functionality. Over time, buoys can experience physical degradation due to environmental factors such as weather conditions, water currents, and biological growth, which may affect their reflectivity, color, and structural integrity. This deterioration can lead to buoys becoming less effective as navigational aids, potentially posing risks to vessels navigating in the vicinity. Therefore, maintaining the condition and visibility of buoys is crucial for safe navigation, making awareness of buoy deterioration a vital aspect of maritime safety practices.
