Which of the following is NOT a factor impacting buoy positioning?

Buoy lettering is primarily concerned with the identification of the buoy and does not influence its positioning in the water. This identification is critical for navigational purposes, enabling mariners to recognize specific buoys and understand their meanings. Factors like water currents, weather conditions, and buoy maintenance directly affect how and where a buoy is positioned.

Water currents can shift buoys from their intended locations, potentially leading to hazards for navigation. Weather conditions, such as storms or high winds, can also affect buoy stability and positioning, as buoys must remain in place to provide accurate navigational aids. Buoy maintenance ensures that buoys are functioning correctly but does not play a role in their initial placement. In contrast, buoy lettering does not have an impact on their physical placement or operational effectiveness in marking navigable channels or hazards.
