Porpoise Analysis - NEW TBDP V7.10 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, velocities and Lift characteristics. By analysis of a hull's design and performance characteristics and comparison to the CPA for each velocity in performance range, TBDP® can predict when the hull is susceptible to porpoising and when it is performing in a stable regime. The XPorpoise is presented in regular TBDP® output and in graphic analysis format. It's simple to interpret when the hull is in the "Porpoise regime" or in the "Stable regime"....AND simple to change setup or design features with TBDP V7.10 to make the hull less susceptible to porpoising.  CLICK here to see more about Porpoise Analysis!  [This feature was requested by a TBDP user - and we responded with the improvement!]

Free Expert Performance Analysis Reports on American Offshore (AO3100), STV (Euro19) and Cougar (21MTR) , and Prowler 246 boats - using TBDP software with complete output data - shows how you can apply expertise to your design/setup. Full sample Reports of TBDP® performance analysis of typical hull designs.

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]

Tips

Approximate propeller sizing can be obtained based on your motor specifications.  Engine RPM is predicted by TBDP7 based on your design, setup parameters and operating performance; your predicted propeller pitch is calculated and displayed with recommendations.  [click to see sample screen]

Deadrise Wizard - If you don't know the deadrise angle of your sponsons, use the Deadrise Wizard to determine the angle of the deadrise of your sponsons or center pod running surface.  Just input the height measured at the outside edge and inside edge, and the width of the running surface (pad) - the Calculator will determine the angle and automatically transfer to the input field.

Design Performance Comparisons are NOW easy, with the Dual Graphic Performance presentation.  Automatically compare the performance trends of your 'new' design trial modifications to your 'base' design, with the Graphic Comparison mode.  Is the new design 'better'? Is it faster?  Is stability improved? It's easy to see now!  Makes it EXTRA EASY to see exactly how the design changes affect performance in all areas.  [click to see sample screen]

Lift and Drag distribution can be easily reviewed and analyzed by using the 'pie-chart' view. The percentage (%) of each Lift (or Drag) component of the total Lift (or Drag) is shown. Check the legend to identify the respective components.

TBPD can simulate 3-point hydroplane performance.
(TBDP is best applied to tunnel hull, power catamaran and modified vee hull designs, but is also used for performance analysis of 3-point hydros).

Vee Hull design - QuickLift Wizard for Vee Hulls and Vee-Pad designs.

[TBDP is best applied to tunnel hull, power catamaran and modified vee hull designs, but is also used for performance analysis of vee hulls and vee-pad hulls.] [This feature was requested by a TBDP user - and we responded with the improvement!]

Automatic WAngle increase – when doing a Velocity Optimization performance check, a new feature will test, if you desire, for all angles of attack (Wangle)  for maximum velocity condition.

Imperial or Metric Units feature - with automatic conversion of all input & output data with click of button.  TBDP can now conform to both Imperial (ft-lb-mph) units and Metric (m-kg-kph) units. A simple "click" on the menu <Change Design Units> and the input units on all screens will automatically change from Imperial to metric – or from metric to Imperial. If design data has been entered, it will be automatically converted to the units chosen. All performance analysis (output) data, graphs, recommendations and charts will also be automatically changed to the corresponding units. [see sample screen for control] [This feature was requested by a TBDP user - and we responded with the improvement!]

Features - Your performance hull design analysis now considers performance and stability effects of Center Pod, multiple sponson steps, selectable aerofoil shapes, cockpit configurations - even single or multiple drive train configurations - and lot's more!

Drive Unit Wizard - Calculates hydrodynamic Drag of any lower unit design and includes standard design specs for 19 drives and ability to calculate for ANY drive design - does all the calcs for 1, 2 or 3 drive configurations - and lot's more! [click here for more details and example]
