What does a Quick Flash mark indicate?

• A. A bend in the channel
• B. A buoy indicating depth
• C. A safe water mark
• D. A no-wake zone

Answer: (A)

Marks that indicate changes in the channel direction use signals that catch your attention and show where the path curves. A Quick Flash mark specifically flags that the navigable channel ahead turns, so you should expect a bend and adjust your course accordingly. It’s a directional warning, not a depth indicator, not a universal safe-water cue, and not a regulatory no-wake point. The other concepts point to depth information, safe-water status, or zones with speed restrictions, which is why this mark is used to alert you to the upcoming bend in the channel.
