I've just posted the only one I have of her in the 'coasters' section, on the slip at Strood on 12/4/81. Not the best of pictures, but there are some other classic LRTC barges in the foreground.
A belated but warm welcome to the site Alan. SN is a sound ship with a very able and willing crew, so I'm sure that your query will bring forth a strong response. Enjoy the site and all it has to offer and we look forward to your postings. Bon Voyage
