Advanced Aerodynamics and Hydrodynamics for Powerboats

The Vee Boat Design Program (VBDP©) shows how your boat will perform, how to optimize performance, economy, top speed and dynamic stability.

VBDP© is a Windows™-based software that completes performance analysis and design for all types of vee hulls and vee-pad hulls. Any size of boat - big or small, any hp - huge or little, any configuration. TBDP©/VBDP©'s easy user-interface makes performance analysis a quick, simple task. (See also TBDP©)AR® maintains the most advanced performance powerboat research programs in the industry.

The VBDP© for vee hulls is included as a full-featured part of the the popular Tunnel Boat Design Program (TBDP©) including detailed calculation methods that are key to effective vee hull design.

$399.

Gives the most comprehensive, complete Performance information through on-screen reports and printed reports with full velocity range predictive data and graphs, including unique 'intelligent' Performance Summary Wizard narrative with key observations and recommendations.

Just describe your hull design on input screens and TBDP©/VBDP© gives you all performance information about your boat design and setup, including a detailed Performance Report narrative and full Performance Graphs.

Optimize vee-pad modifications or vee-pad addition to vee hull.

Quickly: predict maximum speed and hull performance for the complete vee hull velocity range; optimize hull design and setup for specific operating expectations; test vee hull modifications for expected performance BEFORE changing the boat; design new vee hulls for optimum performance; analyze performance characteristics in detail, including dynamic stability, all hydrodynamic and aerodynamic Lifts & Drags, HP requirements, trim angles - even vee hull porpoising analysis; steps design, vee-pad optimization, compare performance of existing design with a new design/mods with on-screen graphics. VBDP© eliminates dramatic costs and expensive time delays from traditional "trial-and-error" design processes.

Vee Pad Design - How does a 'pad' help my vee hull performance?  How can I optimize my 'vee-pad' design? 

Design or modify a center lifting "Pad" for your Vee hull - find out if this feature would be a performance improvement for your boat! Optimize pad width, height, length by comparing ultimate performance of different designs. Many VBDP users have great success with the Vee-Pad design feature for their Vee hull mod projects! Analyze 'Delta-pad' or 'Std'/rectangular shaped pad to optimize performance application. Even notched pad configuration. [see video "Vee Pad Modification" with VBDP©]

Excellent for any size of boat - Sport vee, Offshore vees, Ocean racers (OPC) or Recreational vees, including modified Vee style hulls & Vee-Pad hulls, Bass Boats, even RC performance models. Any size, speed and setup conditions are all accounted for by the software.  VBDP principles perform for all types and any sizes of vee hulls/modified vee hulls and vee-pad hulls.  Any vee or flat bottom deadrise, with or without vee-pad, any hull length, steps, trim angles, any engine setup, any weight distribution - all these and 100 other vee hull design/setup parameters are easily accounted for by VBDP®.

 VBDP© provides a fast, detailed method for the vee boat designer, builder, owner or driver to generate a total performance and design analysis. VBDP© makes it easy to clearly predict the effect of any individual or group of design change(s) on the ultimate performance of the hull. 

The software is not a fancy graphic or drafting-aid package. It is a proven, engineering design/analysis program that presents predictive performance results in easy-to-read, comparative-style format, on any Windows-compatible PC system.

Jim Russell is well-known for his research, development and race-testing of advanced hydrodynamic/aerodynamic relationships, including planing lift/drag, porpoising, chinewalk, hull stability and his expansion of Savitsky equations for high-performance hulls and aero-assisted hulls.

VBDP© allows for unlimited variations of hull designs stored in individual files. All design data dimensions and performance requirements for each design configuration are input to "free-form" data-entry screens, and can be easily changed. Predictive performance results are calculated with the same procedure as outlined in the Secrets of Tunnel Boat Design© book, using specialized algorithms. Many essential performance indicators such as "angle-of-attack", "wetted surface", "power ratings", "acceleration", "elapsed time" and "dynamic stability" relations are determined for full velocity range. Complex design features such as different aerodynamic shapes, steps, any cockpit configuration including enclosed "capsule" cockpits or even "cuddy cabin" or "center-console", multiple power trains, and vee-pad hull designs, can be implemented easily into the analysis. Even effects of geographic altitude and the differences of salt and fresh water are included. The resulting effect on all performance characteristics of even small dimensional or setup changes are seen quickly.
