What is a significant disadvantage of a flat bottom hull?

The significant disadvantage of a flat bottom hull is that it rides roughly in choppy waters. Flat bottom hulls are designed with a wide and flat base, which provides good stability on calm waters and allows for a shallow draft. However, this design can lead to a less comfortable experience in rough or choppy conditions because the hull does not cut through the waves effectively. Instead, it tends to bounce or pound against the surface of the water, which can result in a rough ride for passengers and crew. This is particularly noticeable in open water or when faced with waves, where more contoured hull shapes (like v-bottoms or round bottom hulls) perform better by providing a smoother and more stable ride.
