how would overloading a ship cause it to sink
Answered by The Community. Making the world better, one answer at a time. Overloading a ship will cause it to sink because it will eventually have a lot of mass and it becomes more dense than water which cause it to sink.hips don't sink because air presses on the ship and keeps it buoyant. A ship will float when the weight of the water it displaces equals the weight of the ship.
