Q

If your vessel were proceeding upriver (ascending), how is the port side of the channel marked according to the U. S. Aids to Navigation System on the Western Rivers?

🔍 Key Concepts

• U.S. Aids to Navigation System (Western Rivers) lateral system • Meaning of "red right returning" when traveling upriver (ascending) • Difference between color (red/green) and shape (nun/can) of buoys

💭 Think About

• When you are going upriver (ascending), are you considered to be returning from sea or leaving sea? How does that affect which color is on your starboard side? • Once you know which color is on the starboard side when ascending, what color must be on the port side? • Match the correct shape (nun vs can) to that port-side color under the U.S. system.

✅ Before You Answer

• Confirm that "red right returning" applies when going upriver on Western Rivers. • Verify which buoy shape is normally used for the starboard side color versus the port side color. • Make sure your final choice matches both the correct color for port and the correct shape for that color.
