Your shots are excellent Peter, she is a graceful looking ship.
When the old Queen Mary went to Long Beach, quite a lot of preservation was done on her. The funnels were replaced with stainless steel replicas and a special treatment was applied to the hull to inhibit corrosion. But Andre is right, there is still a huge amount of other ongoing maintenance required to a steel structure in a saltwater environment. When we stayed on ther in September 2001 I noticed that the bottom was dropping out of most of the lifeboats where water had been allowed to accumulate.
