FIELD: transportation.
SUBSTANCE: catamaran comprises a frame and mounted thereon: a saddle, floats made with the possibility of replaceability and rearrangement along the frame length, steering keel control, a stabilising device, a propulsor, and is characterized by the fact that the propulsor is made in the form of a two-pedal drive with the ability to interact with a driving pulley, a belt transmission mounted on the frame and made with parallel belt branches interacting with a driven pulley due to a large sliding friction factor, wherein the belt transmission on the outer sides of the belt is equipped with stroke blades made in the form of second-order curved surfaces of the paraballistic form, directed with their concave part to the opposite side of the catamaran motion in contact with water.
EFFECT: expanding the functionality, providing increased muscular load.
