What type of hull design is characterized by a 20 degree dead rise at the transom?

The correct choice is characterized by having a 20 degree dead rise at the transom, which refers to how the hull's bottom slopes to a specific angle relative to the horizontal plane.

A V-bottom hull design is specifically defined by its V-shaped cross-section, which is responsible for providing better performance in terms of speed and efficiency in rough water conditions. The 20 degree dead rise signifies that the hull is designed to cut through the water more effectively, offering a smoother ride, improving handling, and reducing impacts from waves. This design is particularly advantageous for vessels that operate in choppy or turbulent waters, as it aids in stabilizing the boat and minimizing the effects of wave action.

In contrast, other options do not embody this specific dead rise angle. A planing hull typically has a flatter section allowing it to rise and glide over the surface of the water, often with little to no dead rise. A double chine hull features more than one angle or edge but does not specify a 20 degree dead rise, complicating its categorization. A flat bottom hull is entirely horizontal and lacks a dead rise, making it suitable for calm waters rather than those requiring a sharper angle for effective navigation.

Understanding these distinctions highlights the significance of hull design in relation
