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 initial hull form having a 3 gross tonnage and 30 knots class high speed leisure boat is newly developed based on a statistical analysis method. Fluid dynamics characteristics are studied by commercial CFD code, FLUENT. The effect of a fin attached on the hull side is investigated together. It can be found that the fin plays a role of increasing the resistance performan
