Gareth, I picked up on this thread by chance, my father is also a Bluenose, having served on fishery protection vessels, also he served aboard HMS Caeser (I hope the spelling's right) which is a CA class destroyer, same as the Cavalier presvered at Chatham dockyard, as far as I'm aware they were the last of the open bridge design Destroyer types in the RN.
He went to have a look round the Cavalier a couple of years ago, it brought back a lot of memories, as he left he gave the old lady a pat, to quote Jethro Tull "Last of the breed at an honest days toil".

Great ships, greater men, and a glass and prayer raised to all those who gave their today for our tommrow.
