🔍 Key Concepts
• Purpose of each publication: Nautical Almanac, Coast Pilot, List of Lights, Sailing Directions
• Difference between local U.S. coastal information and worldwide ocean/route planning publications
• Where mariners look for ocean currents, climate, and route planning outside U.S. waters
💭 Think About
• Ask yourself: which option is mainly for astronomical data and celestial navigation, not ocean currents?
• Which publication is focused on U.S. coastal waters only, and which one is designed for international/coastal descriptions worldwide, including currents and climate?
• Which publication is primarily about aids to navigation (lights, buoys, fog signals) rather than water movement?
✅ Before You Answer
• Verify which publication specifically includes descriptions of ocean currents and climatic conditions along coasts and ocean routes
• Check which book is explicitly limited to U.S. waters, and eliminate it for "areas of the world not covered by U.S. NOS"
• Confirm that the publication you choose is used in voyage planning for foreign coasts and offshore routes, not just star data or light characteristics
