i) If cargo is loaded more on sailing ship, its weight increases, so it will displace more water and may sink.
ii) The density of water of different seas is different. When ship sails from a sea of higher water density to sea of lower density it sinks. It is because, by law of floatation, to balance the weight of ship, a greater volume of water is required to displace in water of lower density of sea. 
iii) Each ship has a white line painted on its side known as Plimsoll line. This line indicates the safe limit of loading the ship in waterof density 1000 kg/m3 . 
Thus, if proper precautions are not taken, it causes ships to sink into the water.
