Is a flat bottom hull a displacement hull?

Yes, a flat bottom hull is a type of displacement hull. Displacement hulls are designed to move through the water by displacing a volume of water equal to their weight, and a flat bottom hull achieves this by providing a stable platform that can efficiently displace water. While flat bottom hulls are typically used in shallow water and offer good stability, they may not perform as well at higher speeds compared to other hull shapes designed for planing.
