DynaRig

The DynaRig is a conceptualization of a square-rigged form of rigging, designed in the 1960s by the German engineer Wilhelm Prölß.

While having the appearance of the rigging of a 19th-century clipper ship, it was not actually implemented on a sailing vessel until several decades after its design because of a lack of adequate construction materials.

[1] When the original patent rights and residual technology were purchased from the German government by an American investor in 2001, it was renamed the Falcon rig.

[2] The original concept by Prölß was for a combined rig and hull with extremely high efficiency of operation and the use of wind power to propel a large vessel across an open body of water.

When fully deployed, the sails on each mast have no gaps between them, creating a single panel to capture the wind.
