Hi Stuart,
You can always go ahead a little, until you clear that starb'd dolphin. Then cant the stern out with port helm and a for'd spring to stop further forward motion and finally come astern until you reach the wider part of Beneluxhaven, stop her and swing round 1800 and off you go. There's more ways to kill a cat!!! Just like that, as Tommy Cooper would say.
Regards,
Angus.
P.S. Attached is a mini mission with PoR and her sister ship moored across the other side of the dock, just as shown in Lucs Video. Try this, and I assure you it can be done with PoR swinging at the berth as in reality. Hint, mooring ropes can be used other than for plain mooring.
