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. In recent years ...
Early ships used stern or side paddle wheels, which gave way to screw propellers. The first commercial success accrued to Robert Fulton's North River Steamboat (often called Clermont) in US in 1807, followed in Europe by the 45-foot (14 m) Comet of 1812. Steam propulsion progressed considerably over the rest of the 19th century.
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."
Rotor ship E-Ship 1. A rotor ship is a type of ship designed to use the Magnus effect for propulsion. The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion. "The idea worked, but the ...
A windmill ship, wind energy conversion system ship or wind energy harvester ship propels itself by use of a wind turbine to drive a propeller. They use wind power [1] through a mechanical or electrical transmission to the propeller. Where transmission is electric, storage batteries may also be used to allow power generated at one time to be ...

Alcyone is a ship launched at La Rochelle in 1985 for the Cousteau Society. Alcyone was created as an expedition ship and to test the operation of a new kind of marine propulsion system, the turbosail. Alcyone ' s two turbosails augment its diesel engines. Since the accidental sinking of Calypso, Alcyone has been the Cousteau Society's ...
The shaft was clamped and the ship limped back to Boston mid-Summer 1968, on one propeller shaft, for drydock repairs in East Boston. This negated a planned liberty port call in Edinburgh, Scotland. Eastwind departed Boston 3 weeks later and returned to salvage the remaining Arctic-East summer navigation season in the Greenland Sea.
