This is provided as follows.

Claims

[Scope of utility model registration request]

Immediately after the screw propeller of the ship, a reaction rudder consisting of an upper rudder part and a lower rudder part is provided, and the upper rudder part and the lower rudder part each have a constant irregular horizontal cross section in the vertical direction, and are in a neutral state. A reaction rudder for a marine vessel, characterized in that the rudder is inclined at a required inclination angle in opposite directions with respect to the ship's ship direction.
