Running Rigging

Lines, wire and associated movable equipment used to hoist, lower, trim or control sails, spars and other gear.

Halyards, sheets, guys, lifts, reefing lines and control lines are typical examples, working through blocks, sheaves, tracks, clutches, cleats and winches. Unlike standing rigging, these components move or are adjusted during operation, although some remain loaded for long periods.

Material, diameter, stretch and construction must suit the function. Chafe, glazing, cover-core movement, corrosion, seized sheaves and poor leads increase failure or handling risk, and replacement dimensions must remain compatible with blocks, clutches and winches.

• Halyards are used to hoist or lower sails.
• Sheets are lines attached to the sails’ clews.
• Downhauls and outhauls are used to tension the sails.
• Vangs (boom vangs or kicking straps) are used to control the angle of the boom.
• Reefing lines allow sailors to reduce the sail area in strong winds.
