Wellington is a harbour city so the locals take an interest in the various vessels that come to visit. Cruise ships are common these days, berthed alongside the container ships and various other freighters that use the port as they load and unload their respective cargos.
So if you see locals taking a picture of a ship it’s either something special or something else. This was something else. – maritime utility taken to it’s extreme.
As close as you can get to a floating brick.
