Boats or ships
Ships can be a large craft that carries a people and good over water. These forms of transportation are able to float on water.

The structure of an iron ship is such that its density is less than that of water. Anything with a density less than water will float in water.
Metal ships are built to float.
Ships, boats, anything buoyant, really...
