🔍 Key Concepts

• Lateral buoyage system on the Great Lakes and how “upstream” or “toward the main lake” is defined • How the U.S. system normally arranges aids geographically (e.g., red right returning) and what “returning” means on the Great Lakes • Which specific exceptions exist to the general Great Lakes arrangement

💭 Think About

• Think about the normal direction of buoy numbering and color when you are moving from the ocean or lower water toward the interior of the Great Lakes system—are you generally going west/north or east/south? • Consider which Great Lake or waterway is commonly noted as the exception in Coast Pilot or Light List references, and why that body of water might not follow the general pattern. • Look at the answer choices and match them to your understanding of how an “increasing” direction of buoy numbers is defined for the Great Lakes as a whole.

✅ Before You Answer

• Verify which general geographical directions (westerly/northerly vs easterly/southerly) are associated with increasing buoy numbers on the Great Lakes. • Confirm from your study materials which single lake or canal is cited as the exception to the Great Lakes arrangement. • Make sure you are not confusing the Great Lakes rule with arrangements used on rivers or inland canals elsewhere in the U.S.
