About This Tool
This calculator uses simplified versions of the Savitsky and Crouch formulas to estimate the performance characteristics of a planing hull. It helps determine the required horsepower and minimum planing speed.

Key Concepts:

Planing Lift: Hydrodynamic force that lifts the hull out of the water.
Deadrise: The V-angle of the hull, affecting ride and efficiency.
Speed-Length Ratio: A key indicator of planing efficiency.
Power-to-Weight: The main driver of acceleration and top speed.
