Running rigging refers to the movable ropes, lines, and cables on a sailboat used to raise, lower, and adjust the sails, distinct from the fixed standing rigging. Key components include halyards for hoisting sails, sheets for trimming them, and specialized lines like outhauls, vangs, and traveler lines for shaping the sail to match wind conditions.

Key Running Rigging Components
Halyards: Lines used to raise and lower sails (e.g., Main Halyard, Jib Halyard).

Sheets: Lines that control the angle of the sails relative to the wind (e.g., Mainsheet, Jib Sheet, Spinnaker Sheet).

Boom Vang: A tackle or hydraulic system that pulls the boom down to control sail shape, particularly when sailing downwind.

Outhaul: A line that adjusts the tension of the sail's foot along the boom.

Traveler: A sliding track system for the mainsheet block, allowing lateral movement to control the boom's position.

Reefing Lines: Lines used to reduce the sail area by lowering it slightly.

Topping Lift: A line that holds the boom up when the mainsail is lowered.

Cunningham: A line used to adjust tension in the luff (front edge) of the mainsail.

Preventer: A line that prevents accidental jibes.
