"A", the largest sailing yacht in the world belongs to the Russian billionaire and entrepreneur Andrey Melnichenko and measures 143 m. This three master is equipped with many special features - with an underwater panorama lounge, garages for four dinghies and a mini submarine. The masts are approx. 90 m high and thus the largest free-standing masts made of carbon. The construction is estimated to have cost 400 million euros but actual costs are unknown. The two water-cooled electric motors are used as drives for the bow thrusters. However, they also run as shaft generators or in addition to the diesel engines in booster mode.
