Port is passed to the left. I vaguely remember that the bottle is not to be lifted, just slid. To pour, the bottle is simply tipped so it needs to be quite full.<br />
I can't imagine it's done like this outside of Royal Navy mess halls...
the Dutchie goes left..mibbe the port goes right.
Clockwise around the table.
In my case with the wife doggie i pass the port facing west.
