No longer the leading light.

This lightship was originally moored at Calshot Spit, the entrance to Southampton Water, where it used to guide flying boats into their terminal and warned ships of sandbanks. It retired from service in 1987. She was lifted from the water in 1989 and placed at Ocean Village Marina in Southampton.
I blipped it on my second visit to Ikea. I had to return to collect something I'd bought but left behind!
