[[Running rigging]] is the cordage used to control the shape and position of the sails. Materials have evolved from the use of [[Manilla rope]] to synthetic fibers, which include [[dacron]], [[nylon]] and [[kevlar]].<ref name=HowardDoane>

They have common functions between them for supporting, shaping and orienting sails, which employ different mechanisms. For supporting sails,  [[halyard]]s (sometimes haulyards), are used to raise sails and control luff tension. On [[gaff-rig]]ged vessels, [[topping lift]]s hold the yards across the top of the sail aloft. Sail shape is usually controlled by lines that pull at the corners of the sail, including the [[outhaul]] at the [[clew]] and the [[downhaul]] at the [[Tack (sailing)|tack]] on fore-and-aft rigs. The orientation of sails to the wind is controlled primarily by [[Sheet (sailing)|sheet]]s,<ref name=HowardDoane/> but also by [[Brace (sailing)|braces]], which position the [[yard arms]] with respect to the wind on square-rigged vessels.<ref name="Wolfram"/>
