6.4 Man Overboard (MOB)

If you lose a person or object overboard, and need to return to the location, you
should use the Man Overboard (MOB) function.

You can select the type of data used for the MOB position using the set up
menus (see Section 7.3).

Note: To obtain MOB position, you need either of the following:

Position data from a GPS or equivalent device

Heading and speed data, so that the position can be calculated by dead
reckoning

➤ To initiate the MOB procedure, press and hold the MARKS key for two

seconds. The system then performs the following tasks automatically:

Redraws the chart at 1/2 nm (even if cartography is not available but plotter
mode is on).

Marks the current position with a MOB symbol

which replaces any

current active waypoint and route.

Displays the MOB data box, showing the bearing and distance from your
vessel to the MOB waypoint position, and the elapsed time since the MOB
was initiated (Figure 6-3).

Displays the position data box, showing your vessel’s position.

As your vessel moves from the MOB position, a dotted line is displayed
connecting the MOB symbol and the vessel’s current position.

Sounds a 4-second alarm pattern every 30 seconds.

Sends an MOB message (including bearing and distance) to other units in
the system, via the SeaTalk connection.
