Advanced Aerodynamic and Hydrodynamic
design for Powerboats

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

The Tunnel Boat Design Program/Vee Boat Design Program (TBDP©/VBDP©) is a PC-based (Windows™) computer software that completes performance analysis and design for all types of tunnel hulls, power catamarans, modified tunnels and all types of Vee hulls and Vee-pad hulls.  Any size of hull, big or small, any hp huge or little, any configuration. TBDP©/VBDP©'s easy user-interface makes your performance analysis a fast and simple task for all users. (See also VBDP©)

Determine HOW FAST YOUR BOAT WILL GO!  With fantastic accuracy, extensive flexibility for any hull design, for any size boat, any weight, any power, any configuration. TBDP©/VBDP© software for Performance Analysis makes it easy!

TBDP©/VBDP© doesn't use any 'C' constants or 'factors' to simulate different goups of hull types - it analyzes all design and dimensional aspects of each hull using engineering principles proven by research and verified by full-scale testing. This method of prediction gives highly accurate results based on the critical inter-dependence of aerodynamic, hydrodynamic and stability contributors that are key to proper tunnel hull/vee hull design and accurate performance prediction. NO OTHER SOFTWARE DOES THIS.

How fast will my boat go? When will it become unstable?  Will my boat porpoise?  Can a center-pad make my vee hull faster? What if I change the deadrise of sponson bottoms?  These and dozens of other design and performance questions answered with TBDP©/VBDP© software intellegent report wizard and over  performance data measurments and  performance graphs.

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.
