$P_A = P_B$

Work Step by Step

Since the ship is in equilibrium, the buoyant force on the ship is equal to the ship's weight. The buoyant force is equal to the weight of the water that is displaced by the ship. Therefore, for the points at the floor of the ocean, it does not make any difference if there is a ship or not. The weight of the ship is equal to the weight of the water that is displaced, so the total weight is equal above Point A and Point B. Therefore, $P_A = P_B$.
