Q

A mid-channel buoy, if lighted, will show a __________.

🔍 Key Concepts

• IALA Maritime Buoyage System – mid-channel or safe-water marks • Characteristics of safe water marks (color, shape, topmark, and light pattern) • Difference between lateral marks (red/green) and safe water marks

💭 Think About

• Ask yourself: Is a mid-channel buoy marking the edge of a channel or an area of generally safe water all around? • Think about what light characteristic is used internationally to say "safe water" or "mid-channel" rather than "keep this side". • Which of the listed light characteristics is a standard, distinctive signal that is hard to confuse with red/green lateral aids?

✅ Before You Answer

• Confirm the color and purpose of a mid-channel (safe water) buoy in the IALA system. • Check which light characteristics are commonly associated with lateral marks (port/starboard) and eliminate those choices. • Verify that the remaining light characteristic is specifically associated with safe water / mid-channel marks, not danger or lateral limits.
