Bob Settle has sent me links to a couple of interesting websites :-
The Navy Campaign; http://www.thenavycampaign.com/ . A small, independent, non-profit group that campaigns to promote the Royal Navy and all its constituent parts. There is some good RFA stuff on it but you need to hunt around for it.
Seawaves Magazine; http://seawavesmagazine.blogspot.co.uk/ , Mainly Canadian but with loads of very interesting stuff.
