What is Hydrofoil?
[[File:20091105-TurboJET Urzela.jpg|thumb|200px|A [[Boeing Jetfoil]]]] A '''hydrofoil''' is a type of [[boat]] that can lift its [[Hull (watercraft)|hull]] out of the water with a pair of special wings underwater. These wings are like the wings of an [[airplane]]. == How it works == When a hydrofoil moves quickly, its wings allow it to fly. When this happens the boat is said to be in ''foilborne''. The result of flying means less of the boat is touching the water and can make the boat have less drag which allows it to move faster (drag slows a boat down).or special pontoons when going fast keep it out of the water. == Other websites == {{wiktionary|hydrofoil}} {{commonscat|Hydrofoils}} * [http://foils.org The International Hydrofoil Society] * [http://www.classicfastferries.com Classic Fast Ferries Magazine] {{Webarchive|url=https://web.archive.org/web/20090124192929/http://www.classicfastferries.com/ |date=2009-01-24 }} * [http://www.kjps.co.jp/english/eindex.html Kawasaki Jetfoil] {{Webarchive|url=https://web.archive.org/web/20090830064921/http://www.kjps.co.jp/english/eindex.html |date=2009-08-30 }} * [http://www.rodriquez.it/ Rodriquez Cantieri Navali] * [http://www.riverships.ru/english/types/?grp=3 Soviet-made hydrofoils] {{Webarchive|url=https://web.archive.org/web/20090102015733/http://www.riverships.ru/english/types/?grp=3 |date=2009-01-02 }} * [http://www.hydrofoils.ch Swiss experimental hydrofoils] [[Category:Boats]]
