The condition of the U boat depends on alot of things. I live in Nova Scotia, and if any one has sceen the episode of Clive Custler's Sea Hunters where they dive the wreck of the mine-sweeper HMCS Clayoquot. Since the 190 would be in around the same general location I would expect it to be in simular shape, a good bit of marine growth, and a decent bit of rusting. I doubt it very much that the U-190 would be able to survive a trip to the surface, and weather there would be much left of it to conserve once it reached port, also I doubt very much, unless Halifax shipyard was going to give up a drydock or the synchro-lift, there would be any place to conserve it.
