The color of buoy symbols printed on charts indicates which of the following?

• A. The water depth
• B. The buoy’s color
• C. The wind speed
• D. The vessel type

Answer: (B)

Charts use symbol colors to reflect the real-world appearance of navigational aids. The color of a buoy symbol on a chart matches the buoy’s actual color, so you can quickly confirm you’re identifying the correct mark when you’re out on the water. Depth information on charts comes from depth numbers or shading, wind speed isn’t shown by buoy color, and vessel type isn’t indicated by buoy color. Matching the symbol color to the buoy you see helps you identify marks accurately and navigate safely.
