What does the term "displacement hull" mean?

The term "displacement hull" refers to a type of hull that is specifically designed to push water aside and float rather than rise up and plane over the surface. This type of hull displaces a volume of water equal to its weight, allowing it to float efficiently. Displacement hulls are typically found on boats designed for slower speeds and greater stability, such as sailboats and larger cruisers. These boats maintain a steady and comfortable ride, especially in varying weather conditions.

This concept contrasts with hulls designed for high-speed performance or those that skim across the water's surface, which require different design characteristics to optimize for speed. Additionally, while inflatable hulls exist, they are not defined by their displacement capabilities in the same way as traditional displacement hulls. Thus, the correct answer accurately reflects the primary function and design characteristics of a displacement hull.
