How often does the south cardinal buoy flash?

The south cardinal buoy is designed to signal the presence of a navigational hazard to mariners. Its specified light characteristics are crucial for ensuring that boaters can recognize and interpret the buoy's signals correctly.

The correct answer indicates that the south cardinal buoy exhibits a pattern of 6 short flashes followed by 1 long flash, occurring every 10 seconds. This specific timing and pattern help distinguish the buoy from others on the water and convey vital information regarding navigational routes. The sequence indicates that mariners should navigate to the south of this buoy, providing clear guidance on safe passage in the surrounding area.

The precise sequence and interval of flashes are important for recognition. Other options do not reflect the standard for a south cardinal buoy's light pattern, thereby potentially leading to confusion for a mariner trying to determine their course. Having consistent signaling standards like this is essential for maintaining safety on the water.
