If your boat is in good shape and you're in a harbour it's not a problem. If you're not protected from the open sea by a bulwark of some kind the ice might drift towards land powered by wind and put a lot of pressure on a boat or whatever else is in the way. This will only happen if you're moored somewhere you shouldn't be though. Basically what happens is that your boat just gets stuck in the ice and moves with the ebb and flow of the water. The only problem you have is that you can't go anywhere until the ice breaks up. Last winter I got stuck in the ice somewhere in the Copenhagen harbour a few miles from my homeport and ended up staying there for almost three months.
