Claims

[Scope of utility model registration request]

In a reaction rudder placed behind the propeller of a ship, an upper rudder part above the propeller axis level and a lower rudder part below the propeller axis level each have a horizontal cross-sectional shape extending from the leading edge to the trailing edge. They are curved in opposite directions to follow the rotational flow behind the propeller, and
A reaction rudder characterized in that each trailing edge of the upper rudder portion and the lower rudder portion is formed so that the camber line is substantially parallel to the centerline of the hull.
