| Hullform is available in several versions, of which the lowest is available unsupported as freeware. This version allows design based on up to six longitudinal lines (e.g., chine or keel) with curved surfaces between, and up to 100 transverse sections. Lines can be faired using weighted cubic splines, or can include discontinuities. NACA foil sections can also be generated automatically. Hydrostatic analyses, either on a fixed waterline or free-floating,
give a wide range of outputs such as wetted surface, displacement and righting moment. |
