1.18 Man Overboard (MOB)
Use the MOB function if a person or object falls overboard. You need either position
data from a navigation device, or heading and speed data to calculate position by
dead reckoning. You activate the MOB from the chart plotter display and MOB position
is marked on both the chart plotter and radar displays.
To mark the MOB position, long-push the SAVE/MOB key on the chart plotter display.
Then, the following occurs:
• The MOB mark is put on the chart plotter and radar, at the position when the
SAVE/MOB key is pressed.
• The chart scale is automatically set to 0.250 nm.
• The distance and the time to go to the MOB position appear in the far right-hand
side data box. (Chart plotter and radar displays only).
• A red dashed line runs between the MOB position and your vessel on the chart plot-
ter and radar displays. This line is the course to take to go to the MOB position.
