70% to pass

The Sailing Directions (Enroute) contain information on all of the following EXCEPT _______________.

A ocean currents
B tidal currents
C outer dangers to navigation
D major port anchorages
AI Explanation

The correct answer is A) ocean currents. The Sailing Directions (Enroute) published by the National Geospatial-Intelligence Agency (NGA) contain detailed information on various aspects of coastal and harbor navigation, including tidal currents, outer dangers to navigation, and major port anchorages. However, the Sailing Directions do not provide comprehensive coverage of ocean currents, which are typically found in other nautical publications such as the Pilot Charts or the Oceanographic Atlas. The other answer choices (B, C, and D) are all types of information that are included in the Sailing Directions (Enroute), which is why they are not the correct answer to the question.
