Ever seen drifting in a race boat?? Ride along through the lens of onboard cameras.You'll see team Unpredictable do their best impression of drifting in a race boat at around 2:25. These boats are capable of over 100+ mph,Running in less than 6 inches of water at times. The race boat will drift from one side of te river completely across to the other side.
Ever seen a race boat get vertical?
This was filmed in Riggins Idaho. You'll see the boat in real time then
slowed down to about 40%. Race team #16 comes close to a crash all caused
by a 50 mph head wind. This is as close to a wreck as you can get! The boat
went past vertical when the nozzel of the pump caught the water at the last
second, putting them back into the water. They kept going and never missed
a beat! This was shot in 2006 not 2007 Sorry about the typo.
Helmet Camera: Haulin' Balls Through Hell's Gate Canyon
3 Minutes of horsepower entertainment
through a helmet camera mounted on a rollbar. Brought to you from Team
BOHHICA. You'll head through Hell's Gate Canyon located in southern oregon.
This video was shot on the upper Rouge River. You'll go through Dunn
Riffle, jump through the whitewater and hammer the throttle in the 800 horsepowered jetboat.
Introduction to Whitewater Jet Boat Racing...
Visit us on the web:
A breif explanation of the sport:
Eagle is the number one race hull but there are others racing. Kwikraft is
a New Zealand hull designed and built by Tony Ward, 19 to 21 foot tunnel.
There also is at least one Doug Riddle hull still racing and there are
several unique one-offs, the two built by River Wild are good examples. One
is a 21 foot B-class tunnel and the other is an 18 foot FX class tunnel.
Bottoms are anywhere from .160 to 3/16ths. Sometimes AR plating is used as
an extra layer of protection. Sides are generally .090, decks can be even
less than that. Saving weight is very important and the location of the
weight in the boat is even more important. Most use spoons, an add on piece
in front of the intake. Hulls are generally tunnels although v-hulls have
done well in FX class, and River Wild has built two super light "semi-wing
in ground effect" hulls that are also quite good. The FX version did
especially good in 2001. I believe the Eagle 19 foot Sport step-tech will
become a big force in FX class in the next few years.
Since these boats are raced through whitewater interspersed with rocks and
logs, they need to have fairly precise handling characteristics compared to
other types of race boats. They also need to be very predictable. Bad
habits and quirks can put you up in the rocks or worse.
The pumps are obvously highly modified, but based on Berkeley, Legend,
Aggressor or American Turbine production pumps. Stainless impellers are
almost universal. Full rock grates, although again highly modified, are
also universal. On the higher powered boats much attention is applied to
supplying the thrust bearing with lots of clean lube. Various methods are
used for this including pumps and pressure lube systems. Fabricated steel
nozzles are used almost exclusively, and various combinations of wedges.
The nozzle replaces the entire piece from the bowl back. It's probably
obvious, but maybe it needs stating, the black art of this racing is the
pumps and the hulls.
The engines are pretty straight forward. They have to make good horsepower and torque at
less than about 6500 rpm, but they have to be able to do this fully loaded
down at full throttle for up to 30 minutes. They have to be able to do this
reliably at least twice a day (sometimes more) and for two days in a row.
That's the minimum requirement to finish and you know the saying, "to
finish first, first you have to finish". Rumour has it, and it's only
rumour that I've heard, that some of the unlimited engines are over 650
Engines and pumps are set way back, most of the pump hangs out the back of
the boat. Fuel tanks sizes range from 25 to 35 gallons for an FX boat to 60
to 100 gallons for an Unlimited boat. Usually they are set up as saddle
tanks, at the very back of the hull.
Most boats have run rollbars in the past and it is now a requirement. Most
are made out of aluminum and have double or triple hoops with back braces.
Perhaps we may see a move towards chrome moly construction as the anchoring
and hoop requirements begin to make them a good tradeoff weightwise. Five
point harnesses with lever locks are also a requirement, not to mention a
good idea. Race type lifejackets from Lifeline and Security are also used
as are fire suits.
All boats carry first aid kits, fire extinguishers, two ropes, paddles,
tools, some minor spares and a red flag.
Jet Boat Racings; ~Whitewater Sunday Drive~
Raven Racing Video presents Whitewater Sunday Drive. Music by Saints of
Silence. Ever wonder what it's like to go over 90 mph in a jetboat?
watch the video and tell me what you think about Jetboat racing. While your
at it leave a rating also.
wankel turbo ski race boat
owner has opined, boat is going 105 here but has done 118! That's pretty
fast in a boat that size, especially with the chine walk it's doing.
Driving this would be like laying a 2x4 across a bowling ball and trying to
balance yourself, on ice!!! And people waterski behind these too!!!
