About This Tool
The Deadrise Angle Calculator is a crucial tool for boat designers and builders to determine a hull's 'V' shape. This angle is a primary factor in how a boat performs, affecting its stability at rest, its ability to cut through waves, its speed, and its overall handling characteristics. A deeper V provides a smoother ride in rough water, while a flatter hull is more stable and efficient on calm surfaces.

Key Concepts:

Deadrise Angle: The V-angle of the hull bottom.
Chine: The edge where the hull bottom meets the hull sides.
Stability: Resistance to rolling. Lower deadrise = more stability.
Seakeeping: How well the boat handles waves. Higher deadrise = better seakeeping.
