Why a loaded ship is more submerged than an unloaded ship?

A loaded ship is more submerged than an unloaded ship due to the principle of buoyancy, which states that a floating object displaces a volume of water equal to its weight. When a ship is loaded with cargo, its overall weight increases, causing it to displace more water to achieve equilibrium. Consequently, this increased displacement results in the ship sitting lower in the water, making it more submerged compared to when it is unloaded.
