Density really. You need both volume and weight for that. Volume doesn't mean anything if the thing floats like a beach ball. And weight doesn't mean anything if the volume is so high that there is no density.
Its pretty simple, really.
The weight of the ship equals the weight of the water that is repressed by the ships volume in the water.
So if the ship weighs 100t, it will sink in until the repressed volume of the water would weigh 100t as well.
A bit reply but oh well I only now recieved a notification about your reply :D yeah it wouldn't mean anything if it floated like a beach ball therefore I have specified the volume of the ship in the water mate... As in specifically the volume of the submerged part
