  1. I am now in my 89th year, but I have very many happy memories of holidaying in Dover each year when I was younger, and in particular, going on afternoon ‘cruises’ on board the ‘Lady Savile’ with my father. I would love to get hold of a photograph of the ‘good old tug’; can you point me in the right direction, please? Hope you may be able to help.
