MAN OVERBOARD FACILITY

The Man Overboard Button (MOB) is an optional extra that
activates the Autopilot's Man Overboard alarm procedure. The
MOB can be used whether the Autopilot is engaged or
disengaged.
The purpose of this feature is to aid in the recovery of crew or
passengers lost overboard. By sending the bearing and distance
to the Autopilot, the execution of a "Williamson Turn" can be
achieved automatically. The boat is returned to the position at
which the MOB was pressed.
2.10.1

Man Overboard Procedure

For this facility to operate there is a requirement to have a speed
sensor input. User entered fixed speed or Speed Over Ground
from a position fixer will not activate the MOB procedure.
Sailboats, because of the need to tack or gybe, must use Manual
Recovery. The boat is steered back to the MOB position, following
the bearing and distance displays, either manually or under
Autopilot control.
Powerboat owners, however, can use the Autopilot for Automatic
Recovery. The Autopilot will control the steering of the boat to
execute a "Williamson Turn" and return the boat along the
reciprocal course.
When the MOB is pressed, the Instrument System audible alarm
will sound (if fitted), the LCDs will show the MOB message and if
the back-lighting is ON, the colour will flash from red to green.
Pressing the Enter Key twice on any Full Function Display silences
the alarm.
The full procedures for Manual and Automatic Man Overboard
Recovery are described overleaf. These procedures should be
practised and explained to all crew and passengers on board the
vessel. This practice could help to save a life.
