About This Tool
The Rigging Load Calculator provides essential estimates for the forces acting on a sailboat's standing rigging. By analyzing factors like sail area, wind speed, and rig geometry, it calculates tensions on shrouds and stays, and compression on the mast. This information is critical for selecting appropriate wire sizes and ensuring adequate safety factors, forming the foundation of a safe and reliable rigging system.

Key Concepts:

Righting Moment: The force that keeps the boat from heeling over, which the rigging must counteract.
Mast Compression: The downward force exerted on the mast by the tensioned rigging.
Shroud Tension: The load on the wires supporting the mast sideways.
Safety Factor: The ratio of a component's breaking strength to its working load.
