Here's a question.
At what point did they start the center prop when maneuvering this ship clear
of the dock?
Would seem to me, that if they allowed this prop to simply "freewheel" when
maneuvering and they considered the ship to be "good handling" under this
condition, it would counter the statements that the ship was under ruddered.
However, if they would immediately start the center prop when going ahead
during maneuvering conditions, it would boost the assumption that she needed
this prop wash to improve maneuvering or make it acceptable.
