• Free!Ship Plus  
  FREE!ship Plus is a further development of the program with free sourcecode FREE!ship v2.6 under license GNU GPL. FREE!ship Plus it intended for the full parametric analysis of resistance and power prediction. FREE!ship Plus allows the designer to simulate and analyze condition of balance of a complex completely hull - rudders - keels - engine - propellers. The analyzable system includes hull, appendages, a propeller and the engine (i.e. resistance, power, thrust and torque moment), and also various service conditions (heaving, wind, shallow-water effect, tow / pushing, etc.)   (Added: 8-Apr-2008 Hits: 188)  My Links | Rate | Cached | Visit Free!Ship Plus

• Delftship Free  
  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.   (Added: 8-Apr-2008 Hits: 192)  My Links | Rate | Cached | Visit Delftship Free
