Vaughan - I think we sailed together as cadets! Couldn't tell you on which ships, though. If I remember correctly, we were about the same height (not tall!) and both with dark hair and a 'tache.
If it is who I am thinking of - I have a photo somewhere of us messing about in the ship's pool.
Was the 3/E John Beers and his gorgeous wife Cherie on that trip?
