What do the different colored navigation lines represent?

[DiAngela]

Yellow indicates warnings, red represents congestion, and blue signifies smooth traffic. Navigation lines: Navigation line navigation is a more convenient and practical method compared to bearing lines and distance circle navigation. During navigation, the true motion north-up display mode is used, and navigation lines are set on the display screen. Depending on their function, one or multiple lines can be set to connect. Application of navigation lines: Using navigation lines for navigation is more convenient and practical than using bearing lines and distance circles. During navigation, the true motion north-up display mode is employed, with navigation lines set on the display screen. Depending on their function, one or multiple lines can be established to connect. During navigation, the vessel's course should always remain parallel to the navigation line while maintaining a constant vertical distance d from the guide line, thus avoiding danger zones. When the navigation line's turning point is abeam of the vessel, steering can be initiated to change course. This method can also be used in relative motion display mode. When using relative motion display, it's preferable to select the north-up display mode. In this case, the navigation lines will move while the vessel's position remains fixed on the display, with the navigation method remaining the same as described above.
