The Vee Boat Design Program (VBDP©) is a PC-based computer program that makes the analysis and design of vee hulls and vee-pad hulls extraordinarily fast and simple. VBDP©  incorporates the same design approach as documented in the Secrets of Tunnel Boat Design book©.  AR® sustains the most advanced performance powerboat  research programs in the industry.

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


The User can 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 with the software 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; compare performance of old design with new design with on-screen graphics. VBDP© takes the dramatic costs and expensive time delays out of traditional "trial-and-error" design processes.

Design or modify "Pad" for your Vee hull - find out if this feature would be a performance improvement for your boat! (many VBDP users have had great success with the Vee-Pad design feature for their Vee hull mod projects!)

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© is now a part of the popular TBDP® software, and provides Vee Hull and Vee-Pad hull design & performance analysis, including dynamic stability and Porpoising analysis.  Full performance analysis; one-button click that automatically changes design configuration to reflect the simulation of a Vee hull or a Vee-Pad hull. Key dimensions are automatically changed, with a 1-key click, to reflect the design simulation and nomenclature of a Vee hull or a Vee-Pad hull.
  VBDP© and TBDP© provides a fast, detailed method for the vee boat designer, builder, owner or driver to generate a total performance and design analysis. VBDP© and TBDP© makes it easy for the designer 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.

Tunnel Boat Design Software by AeroMarine Research VBDP© and TBDP© generates detailed performance Reports, showing complete performance measurements of hydrodynamic Lifts & Drags, aerodynamic Lifts & Drags, forces & coefficients, dynamic stability, center of pressures, acceleration, elapsed times - even a unique Porpoise AnalysisPerformance reporting is done NOT just at one selected speed, BUT for ALL velocities throughout the full operating velocity range of the hulls operating performance range.  Data Reports make it easy to compare design changes, whether complex or simple changes, illustrating the regions of performance that are better or worse. Graphic Performance output is also presented for an easy visual review of all performance characteristics.
VBDP© and TBDP© allow 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 special complex algorithms. Many essential performance indicators such as "angle-of-attack", "wetted surface", "power ratings", "acceleration", "elapsed time" and "dynamic stability" relations are determined for specified velocity ranges. Complex design features such as different aerofoil shapes, sponson pad "steps", open cockpit or enclosed "capsule" cockpits or even "cuddy cabin", multiple power trains, and Mod-VP style centre-pod 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 operating changes can be seen quickly.

 Professional features include On-Line Help Screens, Design File Management with Save, Add New, delete and Copy File, and data file printing to any Windows supported printer.

 Results can be easily analyzed with the powerful on-screen-graphic presentation. All of the essential performance indicators are presented in engineering graph format, for your full velocity range, showing the trends of these important indicators throughout the range of operation.

 Detailed results can be saved to individual design files, or can be printed in Design Performance Reports output for further review, comparison or documentation.
