Water craft with a sail

A sailing craft comprising a chassis (1) connecting two float-forming hulls (2) and a sail (5) for wind-powered travel when the floats are on an expanse of water, said craft comprising a central cockpit (6–8) where a helmsman can remain seated and have, within reach, controls for controlling said sail (5) and steering controls which determine variations in orientation, with respect to the longitudinal axis of said craft, of rudder blades (3) with which each of said hulls (2) is respectively equipped, characterized in that said steering controls comprise a handlebar (8) which is fixed such that it can pivot at the end of a handlebar stem (16) and which has two symmetric lateral handles for driving, by pulling on them, two steering control cables (44) each of which is fixed at its respective other end to two symmetric lateral ends of a coordination linkage (47) rigidly connecting two bars which rotate as one with a respective one of the two rudder blades (3), said coordination linkage (47) being situated forward with respect to the rotation axle (50) of said rudder blades (3) on their respective hulls, said cables being forced to follow a guide path with respect to the elements of said chassis which meets said ends of the linkage in a substantially transverse path in order to cause said linkage to move in a translational movement.
