Which of the following is NOT a good technique to navigate through fog?

Navigating through fog presents significant challenges due to reduced visibility, and employing the right techniques is essential for safety. The use of weather satellites, while invaluable for gathering information about larger weather patterns and conditions, is not a practical navigational technique during fog. Satellites can provide data about potential weather systems but do not aid in real-time navigation in low-visibility situations.

In contrast, using a VHF radio allows for effective communication with other boaters, giving you the ability to report your position and receive information about surrounding vessels. Radar is critical as it helps detect objects in the surrounding waters that may not be visible due to fog, enabling you to avoid collisions. Similarly, GPS offers accurate location tracking and assists in navigating to your desired course safely.

Thus, while weather satellites serve a significant role in meteorology, they do not provide immediate, actionable information needed for safe navigation in fog conditions.
