Like others have said, the ghost doesn't use fans to hover--otherwise, it would kick up all sorts of snow and stuff in the snow levels. So if it uses a gravitational sort of a system to stay a certain distance off the ground, the question is whether the water counts as "ground," because otherwise the ghost would just keep on hovering a few feet above the sea floor.
For my money, ghosts CAN skim the surface. Because it would be cooler.
