Porpoise Analysis - NEW TBDP V7 BREAKTHROUGH FEATURE! - We have developed a new analysis tool! XPorpoise is an engineering tool developed by AR that helps predict your hull's inherent instabilities leading to porpoising. The technique is based on a unique Savitsky method of hydrodynamic prediction of the critical porpoise trim angle (CPA) for various hull/setup configurations and velocities. TBD/VBD can predict when the hull is susceptible to porpoising and when it is performing in a stable regime.  CLICK here to see more about Porpoise Analysis!  [This feature was requested by a TBD/VBD user - and we responded with the improvement!]

Free Expert Performance Analysis Reports on American Offshore AO3100, STV Euro19, Cougar 21MTR , Charger 16DL Vee-Pad and Prowler 246 boats - using TBD software with complete output data - shows how you can apply expertise to your design/setup. Full sample Reports of TBD/VBD performance analysis of typical hull designs.  See some of the powerful analytical & reporting capabilities of TBD/VBDas used by Professional designers.

Graphic Performance Results -  Performance Results are presented in Graphic format, for easy review. When predictive performance analysis is complete, the key performance indicators can be shown on-screen in engineering graphic format using the GRAPH option. This is a powerful option that allows you to see the trend of each key performance indicator through the range of specified operating velocities. This shows the changes of every Performance characteristic as the hull design simulation accelerates through the full range of velocities. The GRAPHIC MENU lists all of the data sets available for on-screen plotting in graphic form. The performance indicators as calculated through the predictive performance analysis are plotted on dynamically adjusted graph axes, as a function of velocity. Make a hard copy print of your performance graphs to any windows compatible printer by selecting the <Print> icon on the Graph screen. [Click here to view ALL of the on-screen Graphic Outputs]

Quick Design Wizard makes it easy to obtain a generalized design by selecting one of the 'standard' performance tunnel hull and power catamaran design styles. The dimensional and setup design arrangements for your selected hull type will be automatically applied to all the design input fields. [click to see sample screen]

Performance Report Wizards provide a unique design-based summary of key performance characteristics, including highlighting of important performance & design features and design/setup situations that may benefit from consideration or correction. This is a unique report for your design that can be over 1200+ words of performance wisdom! [click to see sample screen]
