🔍 Key Concepts

• Difference between tides and tidal currents • What type of data each reference (tables vs almanac) is normally used for in coastal navigation • Which publications are specific to U.S. coastal waters, especially the Pacific Coast

💭 Think About

• Ask yourself: which book is designed specifically to describe the horizontal movement of water (currents) near U.S. ports, not just the vertical rise and fall of the sea level? • Think about which choices are actually standard U.S. government publications used on licensing exams for near-coastal navigation. • Consider which reference a mate or master would open when planning to enter a Pacific Coast harbor with strong currents at a specific time and date.

✅ Before You Answer

• Be clear on the difference between tide height predictions and current predictions. • Identify which option is specifically tied to U.S. coastal and harbor current predictions, not open-ocean currents. • Verify which of the listed publications you would normally find grouped with U.S. Tide Tables in a chart room or on a licensing exam formula sheet.
