Claims

[Scope of utility model registration request]

An elongated thin plate is provided at a minute distance from the outer surface of the hull outer plate below the water surface, and the thin plate is arranged so that the longitudinal direction of the thin plate is approximately perpendicular to the water flow direction along the hull outer plate, and A front strut that supports the front part of the thin plate and a rear strut that supports the rear part of the thin plate are respectively attached to the hull so that they can be moved in and out.
A strut drive mechanism is provided for moving these front struts and rear struts in and out, and a strut drive auxiliary mechanism is provided for causing a deviation between the amount of movement of the front strut and the amount of movement of the rear strut. A hull frictional resistance reducing device featuring:
