First night at sea under way

With posts mentioning the landing stage at Liverpool, this reminded me of my short time on the Empress of Canada. As the old landing stage was not considered to be part of the shore, according to the COLREGS, whilst alongside we had to keep sea watches and display nav. lights for a vessel under way but not making way. Is this the casll with the new g stage?
Passing the ro-ro terminal on the Birkenhead side on my many trips to the MSC, the ferries there always left all their NAV. lights on but I guess that was most likely down to ignorance or laziness. I would have thought that those ferries were "made fast to the shore" as per colregs as permanent mooring dolphins were piled into the seabed for their mooring lines (tried to get rid of one when they were building the terminal whilst we were docking in Birkenhead in a gale but only scraped some paint off). On the original landing stage the mooring ropes went to the stage so we were not classed as being made fast to the shore as the stage was not permanently made fast to the shore.
