🔍 Key Concepts

• U.S. Coast Pilot purpose and coverage • Difference between Sailing Directions and Coast Pilot • Where U.S. mariners find detailed info on harbor and bay entrances

💭 Think About

• Think about which publication is designed as a supplement to nautical charts for U.S. coastal waters, giving details like channels, dangers, lights, and harbor entrances. • Ask yourself which book you would open when planning a voyage into a U.S. bay entrance to check depths, currents, and local regulations. • Consider which of these titles are official hydrographic publications versus more generic or local guides.

✅ Before You Answer

• Verify which publication is an official U.S. government hydrographic publication for U.S. coasts. • Check which option normally includes detailed descriptions of bays, inlets, and harbor approaches. • Confirm which book specifically covers U.S. coastal waters rather than foreign coasts or local port administration issues.
