How does a bifurcation buoy signal its flashing sequence?

A bifurcation buoy is designed to indicate specific navigational information to mariners, particularly where waterways split or fork. The correct signaling for a bifurcation buoy consists of a sequence of two short flashes followed by one long flash, repeated every 6 to 10 seconds.

This particular flashing sequence serves a crucial purpose: it helps to guide vessels, indicating where to steer in relation to the diverging channels. The two short flashes signify one side of the channel, while the long flash indicates the other side. This clear and distinct pattern is essential for safe navigation, especially in low visibility conditions.

Using the correct signaling sequence helps ensure that boaters can effectively interpret the buoy's message and make informed decisions, reducing the risk of accidents in waterways that can be busy and complex.
