🔍 Key Concepts

• Tide Tables vs. Tidal Current Tables – one gives water level (height of tide), the other gives the horizontal movement of the water (current) • What type of publication gives predicted times and heights of high and low water for specific ports and dates • The primary purpose of the Coast Pilot and Nautical Almanac

💭 Think About

• Ask yourself: which book is used by small boats and harbor users to know when there will be enough water depth to enter or leave a port? • Which publication is mainly about the motion and timing of currents (flood/ebb) rather than the height of the tide? • Which references are more about general coastal information or celestial navigation, not daily local tide heights?

✅ Before You Answer

• Make sure the choice you pick specifically provides time and height of high and low water at named locations and dates • Confirm that you are not choosing a book that is primarily for currents (speed and direction) instead of water level • Eliminate any resources that are mainly for celestial navigation or sailing directions/coastal information, not tide predictions
