If a vessel is too close to a danger, what does the ECDIS indicate?

• A. It will display a warning message
• B. It will provide an indication if the danger is shallower than the mariner's contour
• C. The ship's speed will be automatically reduced
• D. No indication is provided

Answer: (B)

The ECDIS is designed to enhance navigational safety, and one of its primary functions is to alert the navigator when the vessel is approaching a danger, such as shallows or obstacles. When the vessel is too close to a danger, the ECDIS will provide indications that are pertinent to the navigation conditions. The correct indication when a vessel is in proximity to a danger is fundamentally linked to the measurement of water depth compared to the mariner's safety depth contour, which is typically referred to as the "contour depth." Option B correctly reflects this functionality of the ECDIS, as it notes that the system provides an indication if the danger is shallower than the mariner's defined contour. This is crucial for managing navigational safety, as it offers the mariner essential information about the risk of grounding or collision based on the shallow water conditions ahead. In contrast, while the ECDIS does have warning systems in place (which relates to option A), the specific aspect described in the answer is more focused on depth perception in relation to navigational safety protocols. The ECDIS does not automatically reduce the ship's speed (option C), as such control must still be managed manually by the mariner. Lastly, ECDIS systems
