Abstract
Through the use of wind energy the goals of energy conservation and emission reduction could be realized for ocean-going ships. In this paper the performance coefficients of a sail model and the optimal sail attack angle are determined based on wind tunnel test results. The stability criteria calculation method of sail-assisted ships is proposed on the basis of current literature covering the stability criteria regulations of ocean-going ships. Calculation method for the stability parameter is introduced to investigate the reasonableness of the sail models. Finally a sail model was made and its stability is demonstrated using the proposed stability criteria calculation method of sail-assisted ships.
