Workflow map
Start at the stage that matches the job in front of you; each stage links directly to the calculators and lookup tools that support it.
- 1
Pick wire size
Estimate stay or shroud wire size from load, breaking strength and safety factor.
- 2
Set load share, tension and stretch
Check COG load share, target tension, sling angle factor and elastic stretch for the selected wire and span.
- 3
Specify replacement length
Convert pin-to-pin length, terminals and turnbuckle take-up into a replacement cut spec.
Tools in this workflow
Calculators come first, followed by lookup tools and reference pages when this workflow needs tabular data.
Calculator Standing Rigging Wire Size Sailboat rigging wire required breaking strength, safety factor, utilization, initial tension and elastic stretch from load and wire data. Calculator Standing Rigging Tension Sailboat standing-rigging target tension, measured tension error, turnbuckle take-up, predicted tension, stretch and utilization from wire strength, span and thread pitch. Calculator Standing Rigging Spec Sailboat replacement stay or shroud cut wire length, pin-to-pin breakdown, turnbuckle setup, take-up reserve, turns and stretch allowance. Calculator Wire Rope Stretch Wire rope or standing-rigging elastic stretch, constructional stretch, total stretch, stiffness and metallic area. Calculator Sling Angle Load Multi-leg sling or bridle angle tension, angle factor, required per-leg WLL and utilization from load, loaded legs and sling angle. Calculator Rigging Center of Gravity Two-pick rigging center-of-gravity load share, left/right pick loads, sling-leg tension, WLL utilization and limiting total load.
