Is there any data about why do rocks sink and supertankers float?

Yes, the data dates back to the Greek mathematician, Archimedes. He discovered that when the mass of an object placed on the water is less than the mass of the water it displaces that object will float. Supertankers cover much area with their mass (thus displacing much water), while rocks generally (with the exception, for example, of pumice) do not.
