System Functions
Drift Plot Legend
White-colored vessel contour shows the present vessel's position. It is located in the centre of the plot and directed to
the set heading.
Red-colored vessel contour shows the calculated vessel's position.
Green marker indicates current direction.
Yellow marker indicates wind direction.
Cyan marker indicates wave direction. It matches the wind direction in Auto mode.
Red-colored Watch Circle indicates set drift limit.
Press Change softkey near the Watch Circle Radius text to set a watch circle radius.
In the opened dialog box enter a new value for the watch circle radius and press OK (see Figure 10.73).
Cross time and present heading are displayed under the Drift Plot (see Figure 10.74).
In case the vessel is capable to maintain its position without any drift for the set failure configurations and environ-
mental disturbances (current, wind and waves), the dashes are displayed instead of values for the cross time and heading
(see Figure 10.75).
