What does a white light flashing more than once signify at night?

A white light flashing more than once at night signifies a safe water mark as it is used to indicate where it is safe for vessels to navigate. This is an important aspect of maritime navigation, helping vessels identify areas free from hazards.

Safe water marks are typically used to denote the presence of navigable waters and often feature a light that can be white and flasing at specific intervals. This aids in guiding mariners through channels or ensuring they avoid shifting hazards.

In contrast, danger signals, restricted visibility markers, and general warnings involve different types of lights or signals that indicate either hazards or specific navigational instructions, which do not align with the characteristics of a white light flashing multiple times. Thus, understanding the purpose of light signals in maritime navigation helps in identifying the correct interpretation of the flashing white light in this context.
