PROLINES 8 is a 3D CAD program for the design of virtually any type of marine vessel. As stated by the developer, “PROLINES provides 3D NURB (Non-Uniform Rational B Splines) to define surface shapes for boat hulls. PROLINES also makes extensive calculations of boat hydrostatic characteristics including stability, wave and friction drag. PROLINES exports 3D CAD files in STL, IGES, DXF formats and supports specific files for interface with other industry standard software for more advanced analysis. PROLINES 8 is excellent for Hobby Boat Design, Professional Yacht Design, Commercial Working boat design of smaller vessels. PROLINES has been in development for over 30 years and has developed a following around the world. PROLINES 2019 PRO provides full 3D boat or yacht hull design and analysis capability in a single package. Where competitor software requires purchase of multiple modules for hull design, stability analysis, wave and friction drag evaluation and CAD export files, PROLINES is a single program that offers all of those features in one “module”. PROLINES 8 is especially designed to work with Windows 10 or newer operating systems and to work at very high 4K screen resolution.”
