Hi Swap,
i have just tried this one out for you. You must push the stern of "OCEANA" well clear of the shallow patch near the red bouy at her stern by using one of the inner engines rotated 90
0. Once that is done if you come astern on both inner engines until she is coming astern at a low speed then you may use the bow thrusters to swing the bow to port. I attach 4 pictures which show the sequence clearly. You can see the positions of the controls as the ship clears her berth.
The engines on "OCEANA" must be moved to the ASTERN position,
OR rotated 180
0 and moved to the AHEAD position, as you can see in the pictures. A little confusing I know, but you soon get the idea I hope. I am somewhat baffled by the fact that your controls would appear to be working incorrectly.
Regards,
Traddles
