About This Tool
The Mast Height Calculator is an essential tool for sailboat designers and owners. It helps determine the optimal mast height by balancing performance goals with practical constraints. The calculator uses established naval architecture formulas to estimate sail area, aspect ratio, and center of effort, providing a solid foundation for your rigging design.

Key Concepts:

Aspect Ratio: Ratio of mast height squared to sail area, affects upwind performance
SA/D Ratio: Sail Area to Displacement ratio, a key indicator of power
Center of Effort: The theoretical point where all wind forces on the sail concentrate
Clearance: Practical limits like bridges and transport height
