This boat is my answer to the proposed NAMBA
Offshore class. I really like this class because it required each boat it look
realistic to that of a real offshore boat. Which just proves what people like.
My Boat has been voted #1 as peoples choice at
a local model boat regatta.
Against very well constructed mahogany boats
and scale ships.
This boat will also appear in the January 2000
edition of Marine Modeling International,
published by Traplet UK.

What is in the Kit?
kit comes with the hull and deck pre joined and is made from GRP (fiberglass
reinforced plastic). Along with the hull, other details are also included,
display stand, retaining rail, servo console, pushrod connector, sealing tube,
bellows, steering pushrod, retaining clip, etc. Also included are the fine
details like side mirrors, windshield wipers, cockpit vents, bow rail, etc. The
instructions provided are very clear, show construction of the two options of
assembly, and what types to glue to use on the different materials.
method I picked is my own. Graupner said that it would be to much for the hull.
But I have now got the boat running where I think it works the best, and it does
work! What you will also need is your drive system, the instructions show either
the Z-Drive 600, or twin surface drives (counter rotating). I wanted to run
12cell, so the Z-Drive 800 is what was required for the realistic appearance.
Also a good ESC to handle what ever motor you choose to use, and radio &
batteries. As seen in the left picture, I also custom made exhaust pipes &
water cooling tube to fit.
of the kit was very easy, consisting of a minimum of three parts that needed to
be glued in. I added a couple of other options that are available for the real
B24. The exhaust pipes double as the exits for the water which is drawn up from
behind the prop to cool the motor, which works quite well at full speeds. The
bow rail I found was a bit tricky, if you want to make it look realistic.
GRP material is a bit hard to drill into for angle holes, and tends to chip. The
two glues I found work the best are CA, and a glue called Goop. It works very
well on fiberglass. The rubber seal seen in the left picture wrapping around the
opening was added because I found that water was able to get inside the boat
during normal running, and also helps keep the canopy in place. Also the Velcro
on the back sections was added because in a sudden
tight turns the canopy would slide around and
splash water inside. Finishing the two versions is quite simple, and the decals
provided go on easily. Of course you can do what ever you choose for your own
liking. My self I decided after some thinking, to replicate the first real B24
made. I used silver, & true blue Krylon paint. Along with a couple coats of
the two versions is quite simple, and the decals provided go on easily. Of
course you can do whatever you choose for your own liking. Myself I
decided after some thinking, to replicate the first real B24 made. I used
silver and true blue Krylon paint. Along with a couple coats of clear.
for this section all I can comment on is my own results of the setup I did. The
first time I can the boat, I found it was really jumpy. After trying a couple of
different props, and adjusting the drive angle I figured perhaps Graupner was
right about it being to much for the hull. But I decided to add trim tabs after
I saw that my dad's first mono hull reacted the same way. So the first run after
adding them, the top speed increased, and the boat ran perfect.
In conclusion, I think this is a very well
designed boat. The quality of the kit is excellent, and I highly recommend this
boat for all levels of modelers. Watch out offshore racers, the B24's are
