Review TBDP Ver8.4 Apr2015]
(April 2015) - Jim, the Pad Vee Speedcraft you helped me
design is doing great! She is the fastest SOB on the Island right now!
We managed to a best top speed 100.4 MPH...at a relatively low angle of
attack which kept it stable at these speeds. We were all impressed and
amazed. BD, Speedcraft, Malta
Russell M (March 2017) - TBDP is an awesome tool.
So far it's predictions and actual boat response have been really similar.
The program is so much easier/quieter/cheaper than grinding and sanding! .

TBDP & CAD design (March 2013) - I purchased the Tunnel Boat Design Program (TBDP) from AeroMarine Research. It is really easy to use and covers just about every detail of what ever hull you are working on. ...Enter all of the dimensions/weight placement, power, etc.; there are also templates/examples in the program to compare to; it will give you max speed, acceleration, stability information,
porpoise, etc. and you can change the design until you are happy with it. [MW, Canada]
||"Donzi Mod" [Oct 2011] - I employed the (performance consulting) services of Jim Russell. Jim is very well known in performance circles and has evolved modeling software that can perform numerous "what if" scenarios. He produced a pretty detailed report that had gads of info. ...suffice to say he was worth every penny and routinely is called upon by UAE types for consultation work.

Marine - 21' SportCat, (Feb 2008) - We have been using the Secrets of Tunnel Boat
Design Book to analyse the performance of our new boat with much success,
the STBD book makes complex calculations straight forward and simple to
use, a great tool for anyone designing or setting up cat or tunnel hull
powerboats. Thanks Jim, you and AeroMarine Research
have been a great help and inspiration to all of my projects.

Marine Boating/TKM Racing Developments, (Jan 2009) - I am really
enjoying working with your software and learn more every time I use it! I
have (had) huge success in South Africa. currently (our RC design) holds
the South African Championship! This is really a great testament to your
program as is did wonders in helping to improve and develop our boats!
[Karl Kretz, South Africa]
Jeff & Denise Talcott, (Nov 2011) - your software has really helped us get where we are today. once we had (Denise's) equipment in top form, we were able to go to the TBDP and predict any changes we wanted to make and instantly see the results. we understand why and how her boat performs and can tune to different course, weather and
water conditions and get the most out of every lap. it's that time of year again i keep the wood burner stoked, and go to the TBDP. [Jeff Talcott, MI, USA]
19' Sterling Tunnel - July 2005 -
The Guru Speaks... I submitted drawing, pictures and design notes to
Jim Russell at AeroMarine Research to determine what the performance
characteristics of my boat would be like (most significantly
swapping to twin outboards).
The information and understanding that Jim and AeroMarine were able to
convey to me was extremely valuable. The final point - use Jim Russell's
services and buy his software if you are doing any work on tunnel hulls!!!
The alternative of "trial and error" is expensive, time consuming, and
possibly dangerous. - [David
(AxisMoto), Phoenix, AZ]
Offshore Racing Team - 2004/2005 UIM Offshore Champion, (Feb 2007)
- In 2003 we bought (TBDP) software and started to modify our existing
hull with TBDP. In 2004 we won the championship. We modify our hull
again and we won the 2005
UIM Offshore Championship without losing any race. After 3 years I
started to use the TBDP software like an advanced user. Finally 2006 is
the year of our completely new designed boat powered by TBDP. We won the
championship again!! 4 key factors of our winnings (are) Very High top
speed numbers, Excellent rough water capability and speed, Acceleration,
Higher turning speeds - All the key factors comes from TBDP software
benefits. [Murat Alemdar, Istanbul, Turkey]

"Sleepyhead" designed for NZ Superboat Class. Powered by 2 x
525 Bulldog Mercury racing engines giving it a top speed of 118mph.
Peter Turner wins the NZ
National Championship! When it came to a new boat I had already
purchased your (STBD) book and our designer (purchased) your
program...we input (data from our) last design...then changed every
thing to suit (TBDP) program. We launched it on Saturday 27th of January
took it for one quick run...raced it on the Sunday and won!

Racing - 2nd High Points (TCBA) 2006, Jan 2007 - Driver Tyler Kuhl at
Sioux City, Iowa (photo). Mini-GT Racemaster/Evinrude - Second in
Highpoints 2006 (TCPBA); Third in Highpoints 2005 (TCPBA). The TBDP
Software and STBD Book helped us understand the importance of
Hydrodynamic lift on slower Tunnel boats. It also helped us with dialing
in our motor height and reducing wetted surface drag on the hull. This
program saved us many hours of testing, I wish I had this program 20
years ago when we where running our bigger boats. I would recommend TBDP
software and STBD Book to anyone who has an interest in going fast on
water. Visit Tyler's

Breslin - Sport C World Champion
- (April 2005) - I
highly recommend the Tunnel Boat Design software. It allowed us to
build a boat from the ground up, and test it without even having to
build a prototype first. We were able to test for speed, handling,
and design before we even started the boat. After the boat was
built, it tested within 0.1 mph of the projected speed. I highly
recommend this program.
[Mike Breslin, Black Widow Customs, Sport C World Champion High
Offshore Powerboats - (January 2005)
at American Offshore
have used the AeroMarine software to design the hull for our 37 ft
Cat. It is a very good program and allowed us to evaluate many
different configurations and compare our final design configuration with
those used by other manufactures. It also allowed us to compare our 26
ft and 31 ft hull designs with the similar size hull designs used by our
competition. I highly recommend it. [Art DiNick, American Offshore]
Marles Racing Engines - (January 2005) - I use the program

Tunnel Boat Design Program predicted that our setup would achieve a
maximum velocity of 115.1 mph! (within less than 1 mph of actual top
speed). The TBDP also accurately predicted our acceleration model – a
big plus for drag racers. Impressive accuracy, to say the
least". "Taking this yet another step
further, the Tunnel Boat Design Program assessed the stability of our
STV, arriving at the conclusion that our rig would experience relative
instability throughout the 55-80 mph range...the software was remarkably
accurate: our STV did "settle in" over 80 mph!"
"It is easy to use for even complete novices...pros can dive right
in, and amateurs will find that the program can guide users through each
step. The included Help file is a gold mine of performance boat
knowledge. Each design measurement and aspect of performance is clearly
and accurately defined, along with the related background theory."
"On or off the water, AeroMarine Research’s Tunnel Boat Design
software is a performance-predicting program that is more than worth the
price. There’s just nothing like it anywhere else".

Nelson, (September 2003) - “Jimboat,
this how my (Sport C) boat turned out. It was really fast…Your
program did good work. Mark.”..."I
designed my Sport C boat with the Tunnel Boat Design Software and it
does work! ... It made the designing phase much faster and allot of fun
too! Building your own boat from someone else's plans is OK, but
building a boat that you designed yourself is much more rewarding.
I built a SST-60 boat which won the 2012 OPC National Championships and
set the 1/4 speed record for the class. I used the TBDP for both boats. [Mark

Our Formula One
team bought the TBDP software to find a plaguing problem, in one
of our race hulls, affecting top speed. To our amazement, after
months of trial and failure to right the problem, your TBDP
software went right to it and gave us the answer. Then just for
fun we fed in all the information about our other race hulls and
the out come was unbelievable. The software's potential speed
calculation had the boats within 2 MPH of there actual top speed
readings on radar. I am quite impressed. Thank you
