How do Minemen typically mark a cleared minefield?

Minemen typically use buoys or surface markers to indicate a cleared minefield. This method is effective because buoys are highly visible and can be easily seen from a distance, ensuring that both naval and aerial traffic can identify the boundaries of the cleared area. The use of surface markers also provides a physical point of reference that can be monitored and maintained, helping to keep the area safe for navigation.

Markers such as flags and lights, while useful for signaling in some contexts, may not provide the same level of visibility in a maritime environment, particularly at a distance or in rough weather conditions. Painting markers on the water is impractical, as they can easily wash away and are not durable. Satellite coordinates could potentially be used to record and communicate the location of a cleared minefield but would not serve as a physical marking system on-site for immediate visual identification. Therefore, the utilization of buoys or surface markers is the most effective and reliable method for marking a cleared minefield.
