Question: 1 / 400

In navigation, what purpose does a chart serve?

As a substitute for GPS navigation

To display underwater topography

To assist in plotting a course on water

A chart serves an essential role in navigation by assisting in plotting a course on water. Charts provide detailed information about water bodies, including depths, landmarks, navigation aids, and potential hazards. This information is crucial for mariners to determine the safest and most efficient route to their destination.

While charts often include features such as underwater topography, their primary function is to enable navigators to visualize and plan their movements over water. They help identify safe passages and potential obstacles, thereby enhancing navigation accuracy and safety. This support is vital, especially in areas where GPS signals may be weak or unreliable, affirming why a chart is instrumental for effective navigation beyond merely being a substitute for electronic resources or for showing boat traffic patterns.
