[../../tbdp_banner_include4.htm]
TBDP© Version 8 Released! (V8.0 released 1Mar2014, current , ) [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. Our 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 one software package!

6. NEW "Performance Analysis Wizard" (Report Writer) - A fantastic, powerful, design-based Report that automatically compiles a narrative summary of the unique key performance characteristics for your specific 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 your 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 a Performance Analysys using TBDP©/VBDP© a new Performance Analysis Summary Report is presented with summary results and related recommendations for your specific design, setup and analysis.  This is NOT a 'standardized' report - it's specifically written for your design, setup and your performance results.

7. Advanced Step Design/Analysis - AR® has developed advanced analysis techniques that accurately calculate the performance effects of single or multiple steps in tunnel hulls or vee hulls.  Step design inputs include multiple step locations, step angles, step heights.  Step analysis provides functional wetted areas, force locations, Dynamic Center of Forces locations -  even shows when each step region is wetted/loaded and when it becomes unwetted/unloaded.  Performance Output screens and Graphics show effective wetted surface lengths and step loading for each portion of step activation, including ‘unwetted’ stages. The Wizard Report provides Step performance summary and recommendations for optimization.  
Multi-step design and performance analysis accounts for local step angle, wetted surface, lift location and step effective velocity.

8. NEW “Motor Wizard” feature includes over  OEM engine specs in a selection database, making input of your engine data to TBDP©/VBDP© as simple as picking your motor from a list...ALL the newest OEM outboard and sterndrive engines.  'Motor Wizard' is updated every year, and is the most comprehensive engine specification database available worldwide.
