Abstract In today's world, the fossil fuel is exploited largely, the fuel under the ground is reducing at the high rate. Meanwhile the problem of environmental pollution caused by using a lot of fossil energy has increasingly become global problem. In this condition, all of the world's shipping companies are seeking to reduce fuel consumption and control method of transportation cost. Therefore, they speed up research on renewable clean energy, such as wind and solar power. This paper mainly consists of the following parts. Firstly, research on collection and analysis of relevant information and understand the research status of the sailing boats. Do some analysis of the existing various sail structures of aerodynamic performance to choose a comprehensive comparison and selection of the optimal sail. Secondly, we use wing theory and select the arc profile to match the experimental ship sail size. Thirdly we check the sailing ship stability. Then, we calculate the flow in different speed and different angle of attack of the lift and drag and analyze simulation results through the fluent software aerodynamic performance of the wing analyzing. The numerical simulation results should be applied in the ship to estimate the effect of reducing consumption. Finally， we design an experiment to check the reliability of fluent.
Key words: sail-assisted technology, aerodynamic performance, fluent, stability checking
