Just a little question. Say a boat is floating on water. Imagine now two points in the shallow, flat sea floor. One is below the ship and the other is just water all the way up. Which point has higher pressure? I am imagining that both points have the same pressure due to the concept of hydrostatic pressure: [tex]\rho g h[/tex] But still, I have a little doubt. Wouldn't the boat add a little more pressure along with the atmospheric one?
