Rotor ships use mast-like cylinders, called [[Flettner rotor]]s, for propulsion. These are mounted vertically on the ship's deck. When the wind blows from the side, the Magnus effect creates a forward thrust. Thus, as with any sailing ship, a rotor ship can only move forwards when there is a wind blowing. The effect is also used in a special type of [[Stabilizer (ship)|ship stabilizer]] consisting of a rotating cylinder mounted beneath the waterline and emerging laterally. By controlling the direction and speed of rotation, strong [[lift (force)|lift]] or [[downforce]] can be generated.<ref>{{cite web|url=https://www.youtube.com/watch?v=9CwPHTN2pSs#t=1m26s| archive-url=https://web.archive.org/web/20130721225913/http://www.youtube.com/watch?v=9CwPHTN2pSs| archive-date=2013-07-21 | url-status=dead|title=Quantum Rotary Stabilizers|website=[[YouTube]]|date=2 June 2009}}</ref> The largest deployment of the system to date is in the motor yacht [[Eclipse (yacht)|''Eclipse'']].
