Wind-assisted propulsion is the practice of decreasing the fuel consumption of a merchant vessel through the use of sails or some other wind capture device. Sails used to be the primary means of propelling ships , but with the advent of the steam engine and the diesel engine , sails came to be used for recreational sailing only.
While the design is meant to be usable for different types of ships and even retrofitted to existing vessels, [7] the first vessel from the Oceanbird concept is planned to be a 200 m (660 ft) long roll-on/roll-off ship with a capacity of up to 7,000 cars. Such ships are optimized for transatlantic routes. The first vessel based on the concept ...
Until the application of the coal-fired steam engine to ships in the early 19th century, oars or the wind were the principal means of watercraft propulsion. Merchant ships predominantly used sail, but during periods when naval warfare depended on ships closing to ram or to fight hand-to-hand, galley were preferred for their manoeuvrability and ...

A commercial cargo ship, the MS Beluga Skysails, was built, and launched in 2007, with a kite rig supplementing conventional propulsion. [4] A European Union -funded four-year study of wind propulsion, using the MS Beluga Skysails , reported that the ship attained 5% fuel savings overall, which translated into 530 tonnes (530 t; 580 short tons ...
A cargo ship equipped with high-tech sails saved up to 11 tonnes of fuel per day, according to findings from a six month test of the technology.. The Pyxis Ocean, owned by Japanese automaker ...
According to the Cousteau Society, "when compared to the thrust coefficient of the best sails ever built (Marconi or square types, i.e. ships of the American Cup [sic] or the Japanese wind propulsion system) that of the turbosail is 3.5 to 4 times superior and gives the system a unique advantage for the economical propulsion of ships."
The first such ship to use the Voith Schneider propeller was the excursion boat Kempten. Two German 1935-type M class minesweepers M-1 and M-2 were fitted with VSPs. The first British ship to use Voith Schneider propellers was the double-ended Isle of Wight ferry MV Lymington , launched in 1938.
