Hi Jerry, I must have been at Greenhithe about the same time as you. I was a deck cadet with P&O and there were 7 of us there for our ONC about '79 and '80. I particularly remember rowing and sailing lifeboats on the Thames in winter. We used to drink in the Railway Tavern, cos there were regular lock ins. When the doors were locked, they used to feed us as well!! Also remember the 'Muscle Factory' very well. We were associate members of their Social Club and went there regularly. Many happy memories!
All the best
