Which of the following statements is true regarding shallow and deep contours in ECDIS?

Which of the following statements is true regarding shallow and deep contours in ECDIS?

• A. They generate anti-grounding alarms.
• B. They are primarily for navigation safety.
• C. They are only for informational purposes.
• D. They provide real-time hazard alerts.

Answer: (C)

The statement that shallow and deep contours in ECDIS are only for informational purposes overlooks their primary role in enhancing navigation safety. In fact, while contours do serve to provide information about water depths in a region, their significance extends well beyond mere informational context. Shallow and deep contours are critical for ensuring safe passage through navigable waters. They help mariners identify hazardous areas, such as depths that may be inadequate for the vessel's safe passage, thereby preventing grounding and other dangerous incidents. This aspect of their functionality connects directly to navigational safety, making options like anti-grounding alarms and real-time hazard alerts pertinent to their use. In contrast, the contours serve a practical function by portraying depth variations which are essential for planning and executing safe navigation routes and for making informed decisions based on water depth. Rather than being solely for informational purposes, shallow and deep contours contribute significantly to navigational safety and operational efficiency in ECDIS.
