This paper presents NURBS skinning for the forebody of ship. NURBS skinning is guessed as a good method to generate the faired surface of ship forebody, but it is very problematic in real ship design to generate resonable surface of ship forbody using skinning, because there are lot of problem to apply skinning and to get reasonable surface. One of main problem is data arrangement with design data. Irregular serial contour data arise so serious compatibility problem of knot vector This paper suggests a whole process using skinning successfully in generating hull form of ship forebody This process includes how to make the data set for skinning and how to execute compatibility procedure.
