Wrecked! Jet Boat Racing Nightmare...( Part 2)
The recovery of how 12 guys got a sunken race boat back from the Salmon
River in Riggins Idaho that had sunk earlier during the racing event, It
was perched on a ledge above a 60 foot hole in the river. Highway 95
Idaho's only north to south highway was temporaily closed to allow a tow
truck to lower cables from off the bridge. It took 2 boats,1 Tow Truck, and
12 men to get the boat back onto the trailer safely. During the second leg
of the Idaho Salmon Cup #16 (Wocket) did a barrel roll in some of the worst
whitewater possible on the race course,the rapid is called TIME ZONE. This
video is a trailer of what transpired during the Rescue and You can read
the story by going to www.jetboatracing.com. This is the sequel to part 1
of Wrecked! Jet Boat Racing Nightmare.
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.
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.
SJX Jet Boats Unleashed "You gotta see this!" Vol. 1

SUPER FAST stealth attack boat for the US military and Navy
Another great idea for the us military and us navy . This fast attack
stealth boat will make a difference. GHOST is a super-cavitating surface
craft which is able to achieve 900 times less hull friction compared to a
conventional watercraft and is developed by US Citizens for the US Navy at
no cost to the US government for providing superior protection to US
service personnel. The craft was built by Juliet Marine Systems. The
secrecy orders on the project were removed on 11 August 2011
The Ghost uses a gyro-stabilized dual-pontoon supercavitating hull to run
at top speed through 10-foot seas. Called small waterplane-area twin-hull
(SWATH), it is controlled by 22 computer-controlled underwater control
surfaces. When at rest or moving slowly, the Ghost sits in the water on its
centerline module. At eight knots or faster, the high-grade marine aluminum
buoyant hulls lift the vessel and achieve full stability. Propulsion on the
prototype is provided by T53-703 turboshaft engines, with the company planning to
replace them with the General Electric T700 turboshaft. The Ghost has achieved speeds of over
30 knots, and is being tested to 50 knots. It can perform several different
missions including anti-surface warfare (ASuW), anti-submarine warfare
(ASW), and mine countermeasures (MCM): ASuW armament consists of the M197
20mm rotary cannon and launch tubes that expel Exhaust downward between the struts of the SWATH
hulls, concealing and dissipating the thermal signature of the launch for
BGM-176B Griffin missiles and Advanced Precision Kill Weapon System
rockets, with an electro-optical/infrared (EO/IR) sensor and radar; an ASW
version could be equipped with an EO/IR sensor, radar, sonobuoy launch
tubes, a dipping sonar, and four aft-firing torpedo tubes; an MCM version
could be equipped with a towing boom to lower and raise two towed
mine-hunting sonars, such as the Kline 5000 or Raytheon AN/AQS-20A. The
current Ghost costs $10 million per copy, is crewed by 3-5 sailors, and can
be partially disassembled to fit in a C-17 Globemaster III for transport if
needed. It is designed for fleet protection for navies with few blue-water
needs but require a small and affordable craft in large numbers for
near-shore maritime border patrol and defense missions; it is being offered
to international customers including Bahrain, Qatar, Israel, Saudi Arabia,
Japan, Taiwan, South Korea, and Singapore. High-level discussions have been
held with a foreign nation interested in 25 Ghosts for a potential $300
million sale. Juliet Marine is also offering a scaled-up version of the
Ghost to the U.S. Navy as part of their re-evaluation of the Littoral
Combat Ship program. Plans are to build a corvette-sized Ghost of 150 ft
(46 m) in length or more costing about $50 million per vessel, six times
cheaper than the $300 million per-ship cost of a current Freedom-class and
Independence-class littoral combat ship. One impediment to the U.S. Navy
procuring the Ghost is the desire of senior Navy leaders to have
large-hulled oceangoing vessels that can also perform inshore operations
rather than smaller craft specialized for inshore missions.
Juliet Marine Systems is a maritime technology think tank that is
developing innovative solutions for naval and commercial applications. We
seek to assure fleet force protection in response to small vessel terrorist
attacks against our Navy and coalition ships. There is a clear and present
danger of these tactics being used against the U.S. Navy throughout the
world and in our home ports. These same innovative technologies, applied to
commercial needs, will provide a significant decrease in transit time and
increase in energy efficiency, resulting in the savings of thousands of
gallons of fuel daily.
Our Navy is in a revolutionary period of change. Historic military tactics
combined with modern materials and technology present a formidable fleet
protection challenge for our Navy today. One of the greatest threats to our
Navy is low tech vessel attacks with conventional explosives, as seen on
October 12, 2000, when the USS Cole was attacked, killing 17 sailors and
wounding 39 others and in the continued success of pirates. As a maritime
systems think tank, Juliet Marine Systems provides offensive, defensive and
ISR solutions that are developed in a skunk works operation able to rapidly
invent and construct needed technologies and systems for the Navy and armed
forces. We have already developed a surface variant of a super cavitating
craft and are planning to apply our unique technology in a UUV prototype.
While the GHOST is a surface vessel, the hydrodynamics of the twin
submerged buoyant tubular foils are also a test bed for Juliet Marine's
next planned prototype, a long duration UUV. The GHOST is a revolutionary
proprietary technology vessel platform that will assure force protection
through stealth fighter/attack capabilities along with integrated situation
80 mph winner ski boat,Very Fast race boat
This is a winner ski boat that Mike Ivy at Ivy's Marine, in Flowood
Mississippi, completely rebuilt. He put a 2.5 Mercury race engine on it.
As you can see it is not only Fast but very stable.

A German-flagged container ship headed straight towards shore and
briefly ran aground in Hong Kong on Sunday afternoon (April 6, 2014).
The 192.5-meter-long Hansa Constitution was travelling along the busy
East Lamma shipping channel when it suddenly veered off course.
The Hong Kong Marine Department said the ship's main engine broke down.
People familiar with the shipping industry say the captain and Hong
Kong maritime authorities decided to the best course of action was to beach
the vessel to prevent it from colliding with other ships on the busy
The crew dropped anchor at the last minute, making loud screeching
noises, to slow Hansa Constitution as it headed straight towards the sea
wall outside the University of Hong Kong sports grounds in Pok Fu Lam.
The ship ground to a halt at around 15.22 local. It then slowly
reversed, as Marine, police and fire services rushed to the site. It was
eventually towed free. No one was injured.
The ship was travelling from Yokohama in Japan to Chiwan port in

Getting passed by a 25 Liberator at 110 mph
We were cruising about 50 mph when Wayne Duke came flying by at 110 mph in
a 25 Liberator with twin Mercury 300xs motors. Check out this video of my
25 Liberator reeling in the competition at the 2011 Toys for tots run! It
runs 113 on GPS with 34 cleavers on the rev limiters.
