Which hull type rises and glides on top of the water?

The correct answer is Planing Hull, which is designed to rise and glide on top of the water as it gains speed. This type of hull has a flat, broad shape at the bottom that allows it to generate lift. When a planing hull reaches a certain speed, it can skim across the surface, reducing drag and enabling higher performance. This characteristic makes planing hulls popular for activities such as water sports and high-speed boating, where quick acceleration and efficient performance are desired.

In contrast, other hull types like the displacement hull are designed to cut through the water and displace it, which is more efficient at lower speeds but does not achieve the same high performance as planing hulls. The flat bottom hull typically offers good stability and ease of construction, being well-suited for calm waters, but does not have the lift characteristics necessary for planing. The deep vee hull, while it offers a smoother ride in rough water and can achieve planing at high speeds, is distinct from the design principle of a planing hull focused primarily on gliding on the water’s surface.
