The safe water as defined by the mariner-inputted safety contour is which color when using the night palette?

• A. Blue lines
• B. Red lines
• C. Black lines
• D. Green lines

Answer: (C)

The safe water as defined by the mariner-inputted safety contour is represented by black lines when using the night palette in ECDIS. This choice aligns with the standard conventions set within the system for better visibility and distinction of navigational features during nighttime operations. The use of black lines enhances contrast against the background, allowing mariners to easily identify safe water areas, which is essential for safe navigation and avoiding potential hazards such as shallow water or underwater obstructions. Understanding these visual cues is critical for effective use of ECDIS, particularly during low visibility conditions when precise navigation is essential.
