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 cubic inches!

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.

HULL DESIGN
With the introduction of our Super Ventilated Positive Lift running surface there isn’t a V-bottom pleasure boat on the water that can keep pace with a Fountain. Competitors have tried to copy our designs, but failed because they lack the racing know-how and years of experience and dedication to R&D to make it work.

The speedometer doesn’t lie. Across the board, our boats are 10 to 20 percent faster with better handling and a smoother, safer ride than rivals. The deadrise and longitudinal angles of the running surface must be perfectly matched to the steps to create the proper angle of attack and to help aerate the bottom.

Additionally, Fountain pioneered the notched transom and pad keel, which allows elevated drive heights without sacrificing control, low-end torque or midrange pulling power. Our notched transom design also provides more trim leverage, which allows you to dial in the optimum ride at any given speed for maximum efficiency and comfort.

At Fountain, we spend painstaking hours fine-tuning the weight placement of all our boats for optimum performance. A well designed, properly balanced hull requires less horsepower to propel it through the water and, whether you’re running 35 or 95 mph, there’s less demand on the drivetrain, which is one reason why maintenance is lower in a Fountain.

Finally, a properly setup boat distributes the G-forces where they can be handled best, placing less strain on any specific area of the boat and, subsequently, the occupants inside. Ask anyone, driving a Fountain is a positively uplifting experience.

CONSTRUCTION
We use only the finest materials and begin our production process with a highly polished mold which we researched, developed and built to meet exact tolerances. All of our boats are hand laid with the finest bi-, tri-, and quad-directional fiberglass, Interplastic vinyl ester resins and high density foam core. Interplastic vinyl ester resins is stronger, less likely to delaminate, more flexible and resists blistering better than polyester resins. Foam core, which is used extensively in the aerospace industry, is light weight, doesn’t absorb water and is very strong when used sectionally in high stress areas.

Additionally, we are one of the few boat builders that takes the time to bond the deck and hull together with fiberglass as part of our six-step bonding process to create a unitized construction that is more durable and less likely to flex and break. Fountain’s lamination schedules and techniques have been fine-tuned using the experience we’ve gained from building both race and pleasure boats for over 20 years.
