Different man-overboard manoeuvres may be required, depending upon the situation

prevailing and the type of ship involved.

There are three basic situations:

1. "Immediate action" situation: asualty is noticed on the bridge and action is

initiated immediately!

. "Delayed action" situation: asualty is reported to the bridge by an eye #itness

and action is initiated #ith some delay!

$. "%erson missing" situation: %erson is reported to the bridge as "missing".

&hen a ship ma'es full speed ahead, the follo#ing three standard manoeuvres are

used:

1. (ingle turn )*+ manoeuvre: udder hard over )in an "immediate action"

situation, only to the side of the casualty! after deviation from the original

course by /+, rudder to midship position and stopping manoeuvre to beinitiated.

. &illiamson turn: rudder hard over )in an "immediate action" situation, only to the

side of the casualty! after deviation from the original course by 0+, rudder hard

over to the opposite side! #hen heading + short of opposite course, rudder to

midship position and ship to be turned to opposite course.

$. (charno# turn )not to be used in an "immediate action" situation.: rudder hard

over! after deviation from the original course by +, rudder hard over to theopposite side! #hen heading + short of opposite course, rudder to midship

position so that ship #ill turn to opposite course.

2o#adays these manoeuvrers are not used any more on board modern ships: 3%(

and electronic charts have a "man overboard button" #hich records the ship4s position

and give the navigator the bearing and the distance from the point #here the person

fell.
