I have made countless trips between Portsmouth and the Isle of Wight over the course of my life. Things change but most of the landmarks are remarkably consistent. I was therefore quite surprised to see some very large posts that had appeared in the approaches to Portsmouth Harbour. I knew that there had been dredging work undertaken to allow the new carriers (see this post) to enter the naval base. I suspected that these new large posts might be connected with the same project. Sure enough, some research after our returned confirmed that navigation lights have been installed to allow the carriers to navigate their way in. These light are mounted on top of large posts sunk into the seabed. They aren’t the most attractive things but I guess they do the job.
