I am not a radio expert, but I have spent a lot of time looking at the isolaters and the antenna wire running up to them. They always are located about 4-6 feet above the deck, and no there does not really seem to be much sense in this, particularly when you consider that the antenna wire is in fact part of the antenna and not as some think a lead to the antenna. However, I am not sure how good it would be for the hydraulic ram to be subjected to 5kV, particularly since it is also presumably connected to your hydraulic pump etc.
As to the burns risk, I am sure you could add a tube to the antenna wire leading to your back stay. However, our experience is that when we use our SSB we are both there listening intently - the evening 's entertainment.
What is very important are the spacer tubes you mention. the antenna wire must be kept well away (4 inches) from any parallel metal (back stay).
Bottom line, changing from what you have would be costly, so why do it?
