    What can TBDP/VBDP Do?                                                
   

"The best performance powerboat optimization software available to builders, designers , owners, drivers."

Test your hull:
With Steps, CenterPod, any engine/lower unit, any sponson type/width/deadrise, any tunnel width/height/angle/shape/aerofoil, any tunnel angle (more/less "lift"), spray rails/lifting strakes, any cockpit/cowling design, any deck shape/area, any weight distributions, any engine setback.  Even account for climate, air temperature, humidity, altitude, water temp & type (salt/fresh).

What if I modify...?:
Making changes (major or minor) can be a tedious, time-consuming and costly effort when implemented on a boat/setup, without knowing whether the resulting performance is going to be as expected or not. TBDP©/VBDP© can complete the performance analysis of design changes or 'mods' and display the predicted performance results of the 'design modifications' - compared to the 'base design'.  The 'Performance Analysis Report Wizard' even analyzes the changes for you, predicting how your performance will change.

What can TBDP do?

  • What will the performance of my hull be?  Is my boat design stable at 50mph? 
  • How much power do I need for my hull?  How fast will my boat go? 
  • Will my vee hull porpoise?
  • What is the best size of center-pad for my vee hull conversion?
  • What is my best acceleration time?
  • What's the optimum tunnel height for my hull? How much faster will it go if I reduce tunnel height?  how about tunnel width? 
  • When will my boat start to porpoise?  What can I change to avoid porpoising? When does my hull become unstable? 
  • How does hull deadrise affect my hull speed and performance?
  • Will Steps help my boat's performance?
  • Will a center-pod help my performance? 
  • What happens if I shift weight in my setup?  What is the dynamic stability of my boat?
  • At what speed does my hull experience the "hump zone"? 
  • What difference in performance is my hull if I increase HP of my engine?
  • What happens to my performance if I raise my engine by 1/2 inch?
  • Does engine setback change my hull performance?
  • Is my boat faster with....wider sponsons?  more trim?  less deadrise? smaller tunnel depth?  add a step? 
  • What happens to my speed if I close in my boat's cockpit?  What is my acceleration/elapsed time in 1000ft?
  • How fast will my boat go with "X" HP?  How much HP do I need to go "Y" mph? 
  • How much speed do I gain if I reduce hull weight by "Z" pounds? -
  • Any or ALL of these queries are easy to answer with TBDP/VBDP.

    The User can quickly:
    Predict maximum speed and hull performance for the complete hull velocity range; optimize hull design and setup for specific operating expectations; test hull modifications with the software for expected performance BEFORE changing the boat; design new hulls for optimum performance; analyze performance characteristics in detail, including dynamic balance, all hydrodynamic and aerodynamic Lifts & Drags, HP requirements, trim angles - even porpoising analysis; compare performance of old design with new design with on-screen graphics. TBDP© takes the dramatic costs and expensive time delays out of traditional "trial-and-error" design processes.

    And it all works for vee hulls and vee-pad hulls too!

    There is LOT's more Reports, and recommendations available with the click of your mouse; and there is a myriad of design modifications that you can make to compare your boats performance 'before and after' each design change or feature adjustment - see what is going to work best for your hull and setup BEFORE you have to make costly, time-consuming, permanent changes to your actual boat.

    And there is still the 'Power' Analysis feature that gives all the performance data points PLUS Acceleration curves and Elapsed Time maps.

    And see it all in Comparative Graphic Trend Charts, or detailed data Reports, or Printed Performance Reports.
