About This Tool
The Shroud Angle Calculator is a specialized tool for sailors and riggers to analyze a key aspect of sailboat rigging geometry. The angle of the shrouds relative to the mast is one of the most critical factors in determining how efficiently the mast is supported and how loads are distributed. This calculator helps you assess your boat's rigging design against established best practices.

Key Concepts:

Shroud Angle: The angle between the mast and the shroud, measured from the vertical.
Chainplate Distance: The horizontal distance from the mast's centerline to the shroud's attachment point on the deck.
Mast Compression: A narrower shroud angle significantly increases the downward compression force on the mast.
Rig Efficiency: A measure of how well the rigging geometry supports the mast with minimal stress and weight.
