What best describes the operation mode of a planing hull?

• A. It moves purely underwater
• B. It primarily displaces water
• C. It glides on the surface with less resistance
• D. It functions best at very low speeds

Answer: (C)

A planing hull is designed to operate efficiently at higher speeds by gliding on the surface of the water. This type of hull shape minimizes water resistance, allowing the vessel to rise above the water rather than pushing it out of the way, which is characteristic of displacement hulls. As the speed of the boat increases, the hull creates lift, enabling it to 'plane' on the surface. This operation mode is particularly advantageous for activities that require speed and agility, such as recreational boating and certain fishing applications. Thus, option C accurately captures the unique operational characteristic of a planing hull, highlighting its ability to glide over the water and reduce drag.
