Kites largely consist of specific or besides spars to which a organ or fabric sail is attached, although some, such as foil kites, have no spars at all
- Classic kites use bamboo, rattan or some other strong but flexible copse for the spars, rag or refulgent fabrics such as flocculent for the sails, and are flown on string or twine
- Modish kites exercise synthetic materials, such as ripstop nylon or fresh exotic fabrics for the sails, fiberglass or carbon fiber for the spars and dacron or dyneema for the kite lines.
MS Beluga Skysails is the world's first profit-making container cargo ship partially powered by a big computer-controlled kite (160 mò or 1,722 sq ft). The kite could reduce fuel consumption by 20%. It was launched on 17 December 2007 and was agreed to leave the northern German port of Bremerhaven to Guanta, Wind Spinners Venezuela on January 22, 2008.
