🔍 Key Concepts

• IALA B lateral buoyage system (red right returning in the U.S.) • How numbering of buoys (odd/even) relates to the side of a channel and direction of buoyage • Using a chart for Cape Charles to Cape Henry / York Spit area to see what buoy 19 actually identifies

💭 Think About

• Think about what color and shape buoy 19 would be if it is on your starboard side when you are returning from sea, and what that implies about its function in the channel system. • Consider whether a buoy with just a number (like 19), and no letter, would normally mark a junction, a sector light limit, the end of a channel, or simply one side of a specific channel reach. • Ask yourself: would the visibility limit of a light sector usually be marked by a standard numbered lateral buoy, or by a different kind of aid or characteristic noted on the chart?

✅ Before You Answer

• Confirm from your understanding of IALA Region B which side of the channel odd-numbered buoys mark and in which direction the numbers increase. • Check how the York Spit Channel aids are labeled on the chart: do you see a buoy 19, and what feature is it adjacent to? • Verify what kind of aid is typically used to mark sector light limits—is it a lateral buoy with a simple number, or something more specific on the chart?
