For loaded vessels to float a sizable portion of them have to be below the water line to displace the amount necessary for them TO FLOAT. That area cannot be filled with water as that would cause the vessel to sink due to its weight. Iron Man would have needed to dive under the ship's hull and also welded the split along the keel to prevent it from sinking.
