Introduction to Navigation - MOB
Man Overboard (MOB) Navigation
As soon as you know that you have a man overboard (MOB)
, you should
activate MOB navigation to maximize the chances for a successful rescue.
MOB navigation allows you to create an MOB waypoint to locate the point
at which your man went overboard and the relation of the boat to that point.
Activate MOB navigation:
Press and hold the GOTO key for more than 1.5
seconds to activate the Man Overboard (MOB) function.
When MOB is activated, a MOB waypoint is created at the boat's current
position, regardless of whether the chart cursor is active or not. The MOB
waypoint has a large, distinctive icon. Once MOB is activated, any current
navigation will be cancelled and the current route will be discarded without
user notification. MOB navigation will begin immediately, and the MOB View
will show the following:
• The view will switch to the Chart View, and the elapsed time since
MOB was activated will be displayed.
• A line will be drawn from the boat's current position to the MOB
waypoint, and the MOB waypoint will be targeted.
• The latitude/longitude position of the MOB waypoint will be
displayed in an additional information box.
Cancel MOB Navigation:
From the Navigation X-Press™ Menu, select
Cancel MOB, and press the RIGHT Cursor key. Canceling MOB navigation
removes the route and any waypoints created using the GOTO key but does
not remove any saved routes from memory.
It is not possible to re-activate MOB or modify the current route without
first canceling MOB navigation. The Off Course trigger is also disabled and
the Off Course Alarm circle is not drawn. Any press of the GOTO key, or
selection of a GOTO menu option, will cause an error beep and a short
message will be displayed that will disappear after 2 seconds.
