That doesn't sound right. In theory, water should weight the same in it's frozen state, as it does in it's liquid state since mass cannot be created or destroyed. If it does weight more, that extra mass has to be coming from somewhere.
Are you sure it's heavier, or does it just feel heavier? Cold causes object to condense, so they feel heavier, but they're not. Foil could be a good example. A 12x12 sheet of foil feels lighter than a 12x12 sheet of foil wadded up into a tight ball.
This is also why steel boats float. If all the weight was focused at one point, it'd drop faster than Obama's credibility. Since the weight is spread out over a large area, it becomes less dense, and more buoyant.
