DELFTship™ is a complete design package for application in the marine industry. It is characterised by its ability to create any kind of hullform, high flexibility, low learning curve and visual approach. It can be used for almost any kind of floating object. The basic hullform program is free for all users. The following extensions are currently available for the professional designer:

• Critical points extension (downflooding points etc)
• Crosscurves
• Tank modeling and calibration
• Load cases (intact stability)
• Inclined hydrostatics
• Still water longitudinal bending moment and shearforce calculations
• Maximum allowable VCG' calculations for a selected set of stability criteria

• 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.
  

All hydrostatic calculations are carried out using surface integrals. This results in a more accurate assessment of hydrostatic properties compared to the more traditional method of integrating cross section areas.

DELFTship™^free is a slightly simplified version of the professional hull modeling program but fully functional. Some of the more advanced features or file export formats have been excluded from the free version but otherwise both versions are completely the same. Files created by either version are also 100% exchangable without loss of information. The free edition is capable of displaying tanks created with the tank extension but the tanks can not be modified.

DELFTship™ ^free is perfectly suited for students or home users who like to design and visualize ships in 3D or need to perform simple hydrostatic and resistance calculations.
