The section curves of rigid inflatable planning boat are constructed by free curves and analytic curves based on NURBS curves combination algorithm. The feature extraction and optimization have been launched in the characteristics of the complex section points and improved skinning has also been applied in smoothing surface to precisely construct the planning hull form with knuckle line and broadside airbag. The above methods provide a good solution for constructing complex hull surfaces. It can be a great technical support for automatic partition of hull surface bin, surface block dividing by using CAD/CAM, statics calculation and the generation of constructed mesh in CFD.
