🔍 Key Concepts
• Navigation regulations vs. navigational information (rules of the road vs. general guidance)
• Typical contents and purpose of Coast Pilots, Notices to Mariners, Sailing Directions
• Where U.S. Inland Navigation Rules are normally published and how mariners access them
💭 Think About
• Ask yourself: Which of these publications actually contains the legal rules you must follow for steering and sailing on inland waters, not just charts, corrections, or port info?
• Consider what kind of information each option is best known for: port details, chart corrections, coastal pilotage advice, or international ocean passages?
• Which publication would you study for an exam on inland rules of the road and legal navigation requirements, rather than voyage planning or chart updates?
✅ Before You Answer
• Verify which option is directly associated with regulatory rules (COLREGS or Inland Navigation Rules) rather than supplemental guidance.
• Check which publications are U.S.-specific coastal aids versus international/ocean guidance.
• Eliminate any choice that mainly provides chart corrections, hydrographic updates, or route planning advice, not the actual navigation regulations.
