Because it is a right handed rudder and you are going full astern it will pull the stern to port. So the final heading should be deviated to port. My partners ship is a container ship and I think they will handle similarly. Perhaps his will stop quicker. The LNG will probably come to a stop in 5 min or so. II. LOW FREQUENCY RUDDER CYCLING In a Low frequency rudder cycling situation I think the LNG tanker will stop in about 34 cables.

The LNG will probably come to a stop I 6-7 min. III. HIGH FREQUENCY RUDDER CYCLING In a Hugh frequency rudder cycling situation I think the LNG tanker will stop in 24 cables. Because it is a stopping cycle that has to do with rudder drag it depends which direction
