Well all the old harbours in Lancashire have disapeared over the last 100 years. Some are 20miles inland now. So I suppose if the water level reappears back to normal. All the new marinas will be under water and the old ones will be feasable again. Although maybe not at the 100 years ago prices!!

depends where you are! As I live on one of the few hills in Essex I will inherit an ocean frontage in the new East Anglian arpigeligo <sp?> and therefore will have my own mooring!
Well the North pole will be ice free in about 70 years, but that won't affect sea level. There could be a rash of new marinas in Siberia and North West territiories though.
As Dave-White has hinted, the melting of the North Polar ice cap will theoretically NOT raise sea levels at all. It's basic physics: since the ice cap is floating, it is already diplacing its own weight in water; when it melts the resulting melt water will have the same effect as the original ice on sea levels. Different for the South Pole of course.
Loss of sea ice may mean that the glaciers carve more rapidly, which will (according to the Merchants of Doom) both raise sea level a little and fill the North Atlantic and English channel with icebergs. On the other hand the sea will still freeze in the winter, so there's not going to be a significant change. I think the jury's still out on the precise outcome, but it could start to be a problem by the start of the next century. General consensus on Antarctica seems to be that "Western" Antarctica (Graham Land and Palmer Land, mostly,) may lose its ice sheet periodically (every 10,000 years) but Eastern Antarctica, which contains something approaching 90% of the world's fresh water, will remain intact barring a major catastrophe.
Many of the sea level rise predictions to date were based on salinity measurements, and the assumption that the dilution was due to arctic and antarctic ice melting. It is now apparent that it was almost all due to the arctic sea ice, which means we aren't as doomed as they thought we were, and the Maldives and other low-lying islands are safe for a while yet. Mind you, living on a sand bank in the middle of the Indian Ocean doesn't come into my definition of "safe".
