Man Overboard (MOB) Navigation
(with optional-purchase GPS receiver)
As soon as you know that you have a man overboard, you should activate MOB navigation to
maximize chances for a successful rescue. MOB navigation allows you create an MOB
waypoint to locate the point at which your man went overboard, and the relation of the boat
to that point. When MOB is activated, an MOB waypoint, which is a permanent, sharable
waypoint with a large, distinctive icon, is created at the boat's current position (regardless of
whether the chart cursor is active or not). Any current navigation will be cancelled and the
current route discarded without user notification, and MOB navigation will begin
immediately. A line will be drawn from the boat's current position to the MOB waypoint, and
the MOB waypoint will be targeted. The view is switched to the Chart View automatically
when MOB is activated, and an additional info box that shows the lat/lon position of the MOB
waypoint and the elapsed time since MOB was activated is added to the Chart View.
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 item, will cause an error beep
and a short message will be displayed to the user that will disappear after 2 seconds.
