Which of the following describes the shapes of planing hulls?

Planing hulls are designed to become more efficient at higher speeds by rising out of the water, reducing drag, and allowing for greater fuel efficiency and speed. The shapes mentioned in the correct answer—flat, Vee, and cathedral—each have distinct characteristics that contribute to the hull's performance and stability.

A flat hull provides a stable surface for the boat to glide on the water, making it easier to plane at higher speeds, which is beneficial for shallow water or quick turns. The Vee shape allows the hull to slice through waves more effectively, decreasing resistance and improving handling in rough water. The cathedral hull combines stability with the ability to handle rough waters well, utilizing multiple hull sections to provide lift and minimize drag.

Understanding these shapes helps boaters select the right kind of hull for their specific needs, whether for speed, stability, or maneuverability on the water.
