Hot Boat - July 2005The tricky business of balancing the unique combination of lifts, drags, weights, thrust loads for Vee-Pad hull design is addressed in author Jim Russell's design papers and the VBDP performance analysis software.

Secrets of Propeller DesignThe "Secrets of Propeller Design" book outlines fundamentals of propeller design, Pitch, Rake, Skew, Venting, Cupping, Propeller Types, Fundamentals of Cavitation, Ventilation, Blowout, Slip, Nosecones, Labbing, Gearcase design, Surface Drives, and Speed Calculation formula.

Vee Hull and Vee Pad design - Technical Articles  & Reports:





Vee hull design is addressed in the Secrets of Tunnel Boat Design book (1982-2016).  The new edition includes an added 'History of Modified Tunnel Hull (Mod VP) Design'; 'History & Design of Propellers'; 'History & Design of 'Wing in Ground Effect' (WIG) concepts, and the Ten Steps To Performance Powerboat Design.

The new edition includes the developments of the tunnel and Vee hulls, with detailed explanations of hull design, function, potential and characteristics. This unique book also details ten design steps for analysis of hull performance and stability.


STBD book now also includes:
- Design of Propellers
- Design of Lower Unit/Drive Units
- History of the Modified Vee hull
- Development of Vee hulls
- 10 Steps to performance powerboat design

(ISBN# 1-894933-30-3)



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. The VBDP  incorporates the same design approach as documented in the Secrets of Tunnel Boat Design book (1982-2016).  The VBDP software 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; find out if your vee hull will porpoise; see how your vee hull would perform with a vee pad; 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 balance, 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.

Scream and Fly magazine Review of TBDP/VBDP Version 8
"...the very best and most comprehensive performance evaluation tool available."

Tunnel Boat Design Program Version 8.0
TBDP Ver 8.0 Reviewed by
Powerboat & RIB magazine

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.
