Which of the following is NOT part of the standard navigational information that may be passed to a disoriented mariner?

• A. Charted depth of water
• B. Charted range bearings
• C. Charted hazards
• D. World sea state charts

Answer: (D)

When someone is disoriented, the information given is focused on helping that mariner understand their exact location and what to avoid. Depth of water is a direct clue you can compare with the chart to narrow where you might be on a seafloor contour. Range bearings to known features or landmarks let you triangulate your position relative to things you can identify. Charted hazards tell you immediate dangers to steer clear of. These items give concrete, navigational cues that you can act on right away to reestablish your course.

World sea state charts, while important for overall safety and voyage planning, don’t provide a direct means to fix position or identify nearby dangers from the vessel’s current spot. They describe ocean conditions on a broad scale and require interpretation beyond what’s needed to reorient quickly. That’s why this option isn’t considered part of the standard navigational information passed to a disoriented mariner.
