<P>PROBLEM TO BE SOLVED: To provide an energy-saving device capable of improving a wake gain while suppressing the turning effect of a rudder, and a single-screw twin-rudder vessel equipped with the energy-saving device. <P>SOLUTION: A propeller 120 is installed on the stern 110 of the single-screw twin-rudder vessel 100 within the hull center-line plane. A pair of rudders 140L, 140R are installed on the lower surface 131 of a stern projecting part 130 so as to be freely tilted. An energy-saving device 150 is arranged within the hull center-line plane behind the propeller 120, and the upper end 152 thereof is fixed to the lower surface 131 of the stern projecting part 130. <P>COPYRIGHT: (C)2012,JPO&INPIT |
