What is deadrise on a boat?

Deadrise is a term used to describe the angle of the hull of a boat from the keel to the waterline. The deadrise angle is measured in degrees and typically refers to the V-shaped bottom of the hull. A greater deadrise angle generally means a deeper V-shaped hull, which can help a boat handle rough water more effectively.

The deadrise angle can have a significant impact on a boat's performance and ride quality. A deeper V-shaped hull with a greater deadrise angle can provide a smoother ride in rough conditions, as it helps to cut through the waves more efficiently. However, boats with a deeper deadrise may not be as stable at rest or at slower speeds.

The deadrise angle can vary depending on the type of boat. For example, fishing boats and offshore racing boats often have a deeper deadrise angle to help them navigate rough seas more effectively. In contrast, boats designed for calmer waters, such as pontoons or flat-bottomed skiffs, may have a shallower deadrise angle.

In general, when choosing a boat, it's important to consider the deadrise angle in relation to your typical boating conditions and intended use. A deeper deadrise angle may be more suitable for offshore cruising or fishing, while a shallower deadrise angle may be preferable for inland waterways or lakes.
