The ship has a right-handed propeller and is swinging to starboard when the engines are slow ahead and the rudder is to starboard. The engines are stopped and the rate of swing rapidly slows down. How could the swing to starboard be maintained without the ship making much headway.
Astern on the engines will allow Transverse Thrust to continue the swing
By applying the rudder hard over to starboard and going ahead on the engines.
The only effective method is by using the bow thruster to push the bow to starboard.
Transverse Thrust will reduce the swing and therefore a kick ahead is necessary with full starboard helm applied.

Full power on the forward tug and the after tug ceases to push, but continuously monitor the ship's gyro heading
Considerably more power on the forward tug than the after tug, while monitoring the ship's gyro heading
Experience has shown that the most successful method of double banking (when no tugs used) is:
