TBDP© Version 8 Released!                                                                  [see complete updates list]

ALL the standard TBDP standard features...PLUS...

Some of the cool NEW features added to the TBDP©/VBDP© software in Version 8 include:

1. NEW VBDP© - a most significant NEW element is the incorporation of the NEW “Vee Boat Design Program” full-featured software for “Vee hull and Vee-Pad hull” performance analysis. Users asked for Vee hull design capability, and so we’ve now included it! So the TBDP© now also includes the full VBDP© as part of the software package!

2. NEW Auto Convert program to translate your older TBDP© design data files to the new TBDP©/VBDP© data format – so you easily update your previous design files with new advanced format.

3. More (100+) Input variables, more performance data output information (500+ data points), for more flexible design control and even more performance reporting information - including new Whisker Spray Drags (for sponsons, Center Pod, Vee, veepad); Lift/Drag Ratios (for sponsons, center pod, Vee and Veepad), separate Wetted Area data (SWet) for sponsons, center pod, Vee and Veepad; separate drag coefficients for CDWSponson, CDWVee, CDWPod, CDWPad, Trim Tabs lift/drag/coefficient/Aspect Ratio; along with all the other performance measures that TBDP©/VBDP© has presented in previous versions.

 

More Performance Output screens, 490+ data points, 50+ graphs, showing each performance result as it changes throughout full operating velocity range!


 4. NEW “Auto 1-2-3 Performance Analysis" Wizard - automatically steps you through the 3 steps of performance analysis, to calculate Maximum Velocity, Trim Angle analysis and Power (Acceleration/Elapsed Time analysis) with simple guided button clicks. [GREAT NEW FEATURE used all the time by our power-users!]

It's as easy as 1-2-3 to get the highly accurate performance prediction of your boat. [click here to see how it works] OR check out the "Auto 123 Performance Analysis" video...

6 NEW “Performance Analysis Wizard” (Report Writer) - A powerful design-based Report that automatically compiles a narrative summary of your unique key performance characteristics of your performance analysis, including highlighting of important performance & design features and design/setup situations that may require consideration or correction, and even recommendations.

Each Performance Analysis Summary Wizard notes is different, uniquely generated for the specific design, setup and operating conditions input, and compiled based on unique performance results - so every summary has exclusive highlights, comments and recommendations for your design.

Every time you run the TBDP©/VBDP© a new Performance Analysis Summary report is presented with summary results and related recommendations for your design, setup and analysis.

12. Advanced Cockpit drags - NEW analysis for aerodynamic drag resulting from the exposed cowlings, fairings, cockpit openings and/or cockpit covers, including profile drags, friction drags and NEW contribution from complex cavity drag.

NEW Advanced Cockpit/Cowling/Fairing drag now includes complex Cavity Drag analysis. NEW multiple cockpit/cowling design configurations to select from, including Open, Covered, Race Canopy, Cockpit w/Windscreen, even a Cuddy Cabin

 

Cockpit/Cowling/Fairing analysis considers profile, friction and even complex cavity drag

 


13. TBDP©/VBDP© now calculates hydrodynamic drag of ANY lower unit design; includes standard design specs for 40+ OEM drives, including NEW massive Yamaha and Mercury R400 and HD 300-350hp drives, Merc TorqueMaster, SportMaster, and FleetMaster drives; Merc M8 and drysump outdrives, Merc Verado 350Sci HD, Merc SSM4, Merc SSM6, Nissan & Tohatsu SportC, Tohatsu 50HP D-Stock foot, Suzuki DF and Evinrude ETec HO gearcases, Alpha, Bravo, Volvo IO drives, IMCO SCX drives, Ilmor Indy drives, Arneson surface drives, even RC outdrives.
