The yacht design elements are analyzed by semantics. It extracts the main characteristics of the typical yacht sample parts, makes sorting according to the linear, finds the semantics modeling characteristic line form, and builds the relationship between the whole perceptual image of the yacht. The mapping from design modeling to perceptual image can be quantified and adjusted, and the applicability of reverse Kansei engineering is found in the yacht modeling design method, which provides reference for yacht''s styling design.
