Recently, national attention on the regulations for carbon dioxide emission has risen. Thus, diverse attempts are being actively carried out to reduce the resistance of ships and to develop a new propelling system that reduces the emission of carbon dioxide. This study presents to induce a way to utilize the generated wind power for the electrical energy source of a ship’s lighting, air conditioning and heating by installing a compact wind power facility on the experiment target; a small size high-speed vessel. The vessel targeted for application is a 30ft high-speed leisure boat made of aluminum alloy. The wind power facility installed on the hull and the batteries that will be charged by the electric energy generated by the wind power system were considered at the designing stage of the boat. A new presumption equation for air resistance of wind turbines and efficient measures for management are suggested based on a model test that verifies the basic performance of the wind-powered leisure boat.

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.
