This sounds stupid sorry but I've just gone down a ship rabbit hole and I'm so confused on where the centre of mass should be I originally thought just below the water line but then some sources say above others say below

Then there's the centre of buoyancy which I'm assuming is place of most buoyancy lift but after looking at a diagram I think I'm wrong

Overall I'm curious what forces need to where to balance a ship
