This paper presents the effect of stacking sequence on deformation and hydrodynamic perfor-mance, shape re-design and hull-engine-propeller match for a composite marine propeller. A method of fluid and structure interaction (FSI) is utilized to estimate the hydrodynamic performance of the composite propeller,and its shape is then re-designed via pre-deformation approach. In this way, the matching of hull-engine-propeller is investigated under both design condition and off-design conditions. A conclusion is finally drawn that the propulsion performance of ship can be improved by using composite propeller.
