🔍 Key Concepts

• Differences between navigation tables/references and supplemental sailing directions • Purpose of the U.S. Coast Pilot publications • What type of publication would include environmental protection / marine mammal information

💭 Think About

• Which of these references is specifically designed to give detailed information about coastal areas, hazards, regulations, and local notes for mariners? • Which books are primarily for celestial navigation or sight reduction, and would they normally include whale protection zones? • If you needed to know about seasonal routes, restricted areas, or cautions related to endangered species, which publication would you most logically open first?

✅ Before You Answer

• Identify which options are mainly navigation/astronomical tables (used for sight reduction and celestial calculations) • Identify which option is mainly about medical emergencies and treatment on board • Identify which option provides coastal sailing directions, regulations, and environmental cautions to mariners
