The feasibility study for reducing ship resistance was carried out. A thin plate was installed in front of bow to guide the air which was induced to the bottom just following to the hull surface when ship is running fast. To confirm the reduction of surface friction, model test in the high speed CWC and numerical simulation were implemented. The results show that the induced air to the bottom is increasing according to the increasing of air velocity and it plays an important role to reduce the frictional resistance.
