FREE!ship© is developed to offer an alternative to hullform definition programs based on NURB surface modeling. Most hull modeling packages use these parametric spline surfaces which can be very tricky to use.
FREE!ship© uses subdivision surfaces instead, which offer many advantages over NURB surfaces, such as:

  • No need for a rectangular control grid divided into rows and columns.
  • More freedom in modeling knuckle lines.
  • Surfaces can contain holes.
  • Even the most complex shapes can be created with just one surface.
  • The possibility to insert just one single control point.
  • Not to mention the fact that FREE!ship is totally FREE and open-source.
