DELFTship Free is a fully functional 3D hullform modeling program perfectly suited for students, home users or anyone else with an interest in ship design. DELFTship uses subdivision surfaces to represent the 3D geometry instead of conventional nurbs. This technique allows for rapidly modeling the most complex shapes in a very flexible way.
DELFTship Free will let you model any type of hull, perform basic hydrostatic and resistance calculations, view, print and export the traditional 2D linesplan view which is calculated from the 3D model (shaded or black & white), use the Lackenby hullform transformation to automatically adjust hull parameters such as displacement and longitudinal center of buoyancy to specified values while maintaining fairness of your model, export to various 2D/3D file formats (.STL, .DXF, .OBJ, .GHS etc.), view plate expansions.
Although it lacks some of the more advanced modeling features of DELFTship Professional, files created with either version of the program are fully compatible.
