Standing and Running Rigging

Standing rigging supports masts or spars. Shrouds provide mainly lateral support, while stays support in fore-and-aft directions. It may be wire, rod or suitable fibre, and some boats have adjustable elements. Function, not material alone, distinguishes standing rigging; 'fixed wire that is rarely adjusted' is not a universal definition.

Running rigging is moved or adjusted in operation. A halyard hoists or lowers a sail; a sheet controls a sail's angle and load; reefing lines reduce sail area; and control lines adjust shape or spar position. A kicking strap or vang restrains the boom from lifting and influences mainsail twist on an applicable rig.

Names do not establish safe load, material, condition or handling method. Before using a line, identify both ends, its route, the hardware it loads and the consequence of releasing or tensioning it. Stop if the boat-specific arrangement is unclear.
