The concept of the rotational sail was developed back in the 1920s, but since then this idea has continued to remain only an idea, despite the construction of several experimental ships with such sails. Here we are with youconsidered the principle of such a sailand these experimental ships. And only recently, the sail of the Rotor Sail Solution, which is a large vertical cylinder, was installed on the vessel M / S Viking Grace, owned by the Finnish company Norsepower, which makes regular flights between Finland and Sweden.
The M / S Viking Grace has 800 cabins and can accommodate up to 2,800 passengers, and there is space for 500 cars in its hold. This vessel was commissioned in 2013, it was the first vessel of this size, whose engines run on liquefied natural gas (Liquefied Natural Gas, LNG). To increase the efficiency, the hull of the M / S Viking Grace was maximally optimized from the hydrodynamic point of view, which made it possible to reduce the amount of fuel consumed and the level of noise emitted.
The only Rotor Sail cylinder, 24 meters high and 4 meters in diameter, is the modern version of the so-called Flattner rotor (Flettner rotor). This technology uses the Magnus effect, which provides maximum thrust at an angle of 90 degrees to the direction of the wind. The Rotor Sail system uses sensors that determine the strength and direction of the wind, and when the wind becomes strong enough, the rotational sail makes a significant contribution to the movement of the vessel, which saves a very substantial amount of fuel.

According to preliminary calculations, the savings in fuel consumption due to the use of the rotary sail Rotor Sail will reduce the carbon emissions of the vessel M / S Viking Grace by 900 tons per year.
From April 12 of this year, the vessel M / S Viking Grace, equipped with a rotational sail, began to carry passengers from Turku, Finland, to Stockholm, Sweden. And another company, Viking Line, plans to install two rotary sails Rotor Sail on a new ferry, which is currently under construction and will be launched in 2020.
