Running rigging refers to the adjustable ropes, lines, and cables on a sailboat used to raise, lower, trim, and shape the sails while underway. Unlike fixed standing rigging, running rigging is dynamic, constantly adjusted to optimize performance in changing wind conditions. Key components include halyards for hoisting, sheets for trimming, and vangs/cunninghams for shaping.

Core Components of Running Rigging:
Halyards: Used to raise or lower sails (e.g., main halyard, jib halyard).

Sheets: Control the angle of the sail relative to the wind (e.g., mainsheet, jib sheet).

Vang (Kicker): Controls the vertical angle of the boom, affecting sail twist.

Outhaul: Pulls the bottom corner of the sail (clew) along the boom to flatten or deepen the sail.

Traveler: A track system for controlling the mainsheet's attachment point on deck.

Downhaul/Cunningham: Tensions the luff (front edge) of the sail to control shape.

Running rigging is usually made of rope (lines) and works with winches and clutches, in contrast to standing rigging, which is typically wire that holds up the mast.
