In the 1950's i was on the training ship arethusa and started my C. S. Forester, Hornblower series plenty of headroom though cockroaches could be a problem. Briefly 1950's HMS Victory the main baracks, but made several trips and tours of HMS Victory itself. Was there not a mock-up of the gun decks on the quayside c/w suitable cannon fire and smoke?? This was fed by Hornblower books, later came Patrick O'Brian with his excellent descriptive novels. Peter
