A planing hull has which of the following characteristics?

A planing hull is specifically designed to rise and glide across the surface of the water at higher speeds. When a boat with a planing hull accelerates, the shape of the hull allows it to lift out of the water, reducing drag and increasing speed as it rides on top of the water rather than through it. This design is efficient for quick movement and is commonly found in powerboats and recreational vessels.

The other characteristics listed do not accurately define a planing hull: it doesn’t dive underwater (which would be more characteristic of a submarine or similar vessel), it does not necessarily weigh more than a displacement hull (in fact, many planing hulls are designed to be lightweight for performance), and while planing hulls can use more fuel than displacement hulls at lower speeds, their efficiency at higher speeds can vary. The fundamental trait of a planing hull is its ability to ride on top of the water effectively when the boat gains significant speed.
