A directional control system of a marine vessel includes a steering control member manually operated by a user and operationally connected to a direction-variation member acting on or in the water, such as at least one rudder blade or at least one outboard engine, the direction-variation member having an angular position that is controlled by the steering control member; and a locking system locking the free variation of the angular position of the direction-variation member, which can be activated and deactivated to allow the variation of angular position and carry out a directional change, the locking system including a hydraulic cylinder having a piston dividing the cylinder into two chambers, which are connected by a bypass circuit that can be opened and closed by a switching member. According to the invention, the fluid in the hydraulic circuit is a magnetorheological fluid, and a magnetic field generator, which can be activated and deactivated by the switching member, is combined with the bypass circuit, the magnetorheological fluid changing viscosity depending on the generated magnetic field, switching from a fluid condition to a substantially solid condition or viscosity that prevents flow in the bypass circuit.
