The JAE 21G2 was designed and developed as a result of a joint venture between IMPBA Hall
of Fame member Rod Geraghty, David Hall, Ron Zaker Jr. & Martin Truex Jr.
The main difference between this hull and all the others is the use of sharp edges on the bottom
of the sponsons and tub, as opposed to curved surfaces. This helps break any surface tension
of the water and makes for a faster boat.
This design approach has been built, developed and tested a great deal.
The JAE 21 holds many speed records, and is currently the fastest boat in the world on the ¼
mile oval course (16.0 seconds/ 2 laps).
These records were broken by an expert boat racer named Kently Porter.
His picture is on the cover of this manual. KP has set some 35 records in the past, and currently
holds 19. He knows what he is doing!
We asked Kently to write a few suggestions for building and running this kit…
“The thing that I want to impress the most is to build the kit as the manual shows!
It is a good design, handles excellent (even at 84 mph) and has no bad habits. Don’t try
to second guess the designers! This hull is the absolute pinnacle of model hydro design.
The reason that there are no adjustments on this hull is that it doesn’t need any. That has
all been done for you.
If you take your time and build a straight, true hull, you will have most of what it takes to
win.
The rest is up to you. Make sure you have a reliable engine, and burn lots of fuel!
Test different props. I like the ABC H-7.
Get comfortable driving this hull. It is so fast (especially in the turns), it will scare you the
first few times on the course.
You will learn that you can drive this hull in any lane you want, and rough “race” water is
welcome!
Finally, make sure that you pay attention to the details. Everyone always asks what it
takes to make a boat really fast. It’s not one thing, it’s hundreds of tiny details, all worked
out and optimized. Try anything, if it gets better, keep going. If not, try something else.”
Well said KP!
We are reminded of what someone once asked:
What can I buy to help me win more races?
A case of fuel…
