What light rhythm is associated with Safe Water Marks?

Safe Water Marks are identified by their distinctive light rhythm, which serves as a navigational aid to indicate that there is safe water ahead and to guide mariners. The correct answer indicates that Safe Water Marks emit an occulting light, specifically one long flash every 10 seconds. This rhythm is designated to provide minimal confusion for mariners while still being easily identifiable among other buoyage systems.

The use of a long flash every 10 seconds allows mariners to recognize the Safe Water Mark from a distance, ensuring they can navigate safely through maritime routes. This light signal plays an essential role in maritime safety, especially in areas where navigation can be challenging.

Understanding the specific light rhythm functions to differentiate Safe Water Marks from other types of buoys, which have different rhythms and characteristics for various navigation purposes, enabling mariners to maintain safe passage based on visual cues.
