What is a Boat’s Deadrise and Why it Matters for Performance and Comfort

The design of a boat hull can have a major impact on the overall performance, efficiency, and stability of a vessel. There are many aspects of a hull, but one of the most important features that offers a great comparison point for different boats is the “deadrise.” Learn more about what deadrise is and why it matters for performance and comfort.

What is Deadrise?

Most boats have a V-shaped hull. These angled hulls drop below the surface, and the V shape allows the vessel to cut through water and waves. Generally speaking, the sharper the angle, the more the boat can cut through water.

The deadrise of a boat is a measurement of the angle at which the boat’s V-shaped hull rises from the bottom point of the V.

For example, a flat-bottomed boat would have a zero-degree deadrise, as there is no angle. However, most boats use a V-shape which can have a deadrise from 10 degrees to as many as 50 degrees.

However, most hulls have multiple deadrise measurements, which are generally higher or steeper towards the front, then become lower at the back. For example, a boat might have a deadrise of 35 degrees at the front, which will then slope to a deadrise of 25 degrees towards the middle. Near the back, the deadrise could flatten to 15 degrees, give or take.

Why Does Deadrise Matter?

Deadrise matters to boaters because it provides a useful metric for determining how well the boat will perform while speeding across the water or moving in rough, choppy conditions. A larger deadrise (higher angle) will cut through seas and lakes more easily and will generally provide a smoother ride, especially at higher speeds. A low deadrise, on the other hand, will slam into waves with more force, creating a harsh ride when traveling at high speeds.

The Disadvantage of A High Deadrise

But there is a disadvantage to having a high deadrise. When the angle is sharp, the boat’s hull sinks lower into the water, which means you won’t have the same amount of access to shallow waters that are enjoyed by low-deadrise boats. This is the reason that flat-bottom boats are the craft of choice for shallow-water fishing or boating in marshes and wetlands.

Boats with the Most Desirable Deadrise from Scout

Most manufacturers—Scout Boats included—try to find a happy medium for deadrise. We design our hulls in-house, which allows us to create a hull with the perfect deadrise for maximum performance.

The hull on the 175 Sportfish, a small boat intended for versatile fishing, has a listed deadrise of 13 degrees. This allows the boat to access shallow-water fishing locations. On the other hand, the 420 LFX has a deadrise of 22 degrees, which creates better stability for this larger craft.
