First time user of Fastship can easily present a complete hull form of the yacht by pressing Reflected Image button in the toolbars to show both sides of the hull form.
Another naval architecture software that is available for free is Delfship. Ship or yacht designers can download the fully functional free version from its official website at delftship.net. Although designing yacht can now be done by computer software, a comprehensive knowledge about hydrostatic and hydrodynamic principles of yacht have to be studied by designers to ensure that the marine vehicles which they design are safe and stable.
