We often see ocean liners in the Firth of Forth.
The smaller ones come into Leith docks where there is a cruise liner terminal.
The larger vessels won’t fit through the lock into the docks so instead they moor midstream off South Queensferry & passengers who wish to come ashore to see the sights are ferried to the jetty by tender.
Queen Victoria is one of the Cunard fleet of cruise liners & I managed to find several vantage points for photographs.
