Question 1 of 31048

Information about direction and velocity of rotary tidal currents for a Port on the Atlantic coast of the United States can be found in which publication?

🔍 Key Concepts

• Differences between tide and tidal current information • Typical contents of Tidal Current Tables versus Tide Tables • Which publication mariners use for direction and velocity of currents at specific ports

💭 Think About

• Ask yourself: which of these publications is specifically designed to give set (direction) and drift (speed) of moving water, rather than just water levels? • Consider what kind of information a navigator needs when planning to enter or leave a port with strong currents. • Think about which of these books astronomers use versus what everyday coastal navigators use for currents and heights of tide.

✅ Before You Answer

• Identify which option deals with currents (movement of water) rather than just height of tide (water level). • Eliminate any publication that is primarily about astronomical data for celestial navigation. • Confirm that the correct book includes tables or diagrams showing direction (in degrees) and rate (in knots) of the current at various times of the tidal cycle.
