Q

Under the IALA Buoyage Systems, a yellow buoy may mark __________.

🔍 Key Concepts

• IALA buoyage systems (Region A and B) and the general meaning of yellow special marks • Difference between lateral marks (red/green) and special purpose marks (yellow) • Examples of areas that are often marked for special purposes rather than for safe water or channel edges

💭 Think About

• Ask yourself: In the IALA system, what is the primary use of yellow buoys compared with red or green buoys? • Think about which of the listed areas would need to be identified for information/special purpose, not to mark the sides of a channel. • Consider whether a yellow buoy is tied to just one of these uses, or if it can be used for multiple types of special areas.

✅ Before You Answer

• Verify what the IALA system defines as a special mark and what color it uses. • Check whether examples like military exercise areas, spoil grounds, and fishing areas fall under that “special mark” category in your study materials. • Confirm that you are not confusing yellow special marks with buoys that mark isolated dangers, safe water, or lateral channel edges (which use other colors and shapes).
