Teacher: Now, understand the problem? Solve this instance: Passage: 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. Running rigging varies between fore-and-aft rigged vessels and square-rigged vessels. They have common functions between them for supporting, shaping and orienting sails, which employ different mechanisms. For supporting sails, halyards (sometimes haulyards), are used to raise sails and control luff tension. On gaff-rigged vessels, topping lifts 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 on fore-and-aft rigs. The orientation of sails to the wind is controlled primarily by sheets, but also by braces, which position the yard arms with respect to the wind on square-rigged vessels.
