Displacement hulls are a type of boat design that allows vessels to move through water by pushing it aside rather than riding on top of it. This design is efficient for slower speeds and is commonly found in larger ships, such as cargo ships and yachts. The shape of a displacement hull is typically rounded or V-shaped, which helps to minimize resistance and improve stability. Unlike planing hulls, which lift out of the water at higher speeds, displacement hulls remain submerged, creating a wave as they travel. This characteristic makes them ideal for long-distance cruising and heavy loads, as they can maintain a steady course and handle rough waters effectively.
