Why does the bottom of the boat appear to be larger than the top of the boat in water?

The bottom of the boat appears larger than the top due to the principles of buoyancy and perspective. When a boat is in water, its hull is designed to displace a volume of water equal to its weight, resulting in a wider, more stable base for support. Additionally, the angle of viewing from above can distort perception, making the submerged portion seem more prominent compared to the narrower top structure. This optical illusion reinforces the perception of a larger bottom compared to the top.
