Drag boat racing is very similar to its asphalt
cousin. The biggest difference is the medium.
Because water is unpredictable, drag boat racing
is an exciting, explosive sport. In Asphalt drag
racing, the vehicles start from a dead stop. In
drag boat racing, boats are given a 125 foot approach
to allow boats to achieve a stable plane. Boats
run down a straight ¼ mile course (1320
Feet). There are two lanes, each measured with
it's own timing device, to record elapsed time
as well as mile per hour. The start of the race
is set to a 40 second countdown, of which the
last 10 seconds are counted down on a visible
clock. The boats leave their positions on the
holding rope and travel 125 feet to the start
line. The object of the start is to cross the
line as close to, but not before the clock reaches
zero. The competitor to cross the finish line
first is claimed the winner, unless he had reached
the start line before zero, then he would be considered
disqualified.
Drag boat racing consists of 14 different
classes. The top six classes make up the sports
pro categories. The remaining classes are considered
bracket categories. Classes are designated by
hull type, intake setup, and fuel type. The fastest
of the hull types are called hydroplanes. The
others consist of jets, and flatbottoms. Hydroplanes
achieve their tremendous speed by developing an
air foil under the hull in it's tunnel, similar
to an airplane, which allow the boat to almost
fly. Hydros and flatbottoms both use a hybrid
steel propeller in order to transfer the power
of the motor to the water. Jet boats use a specially
designed pump that takes water in an opening in
the bottom of the boat and pushes water with an
impeller out the back through a nozzle that not
only pushes the boat but also steers it.
One of the fastest classes in drag
boat racing is the Top Alcohol Hydro. Derived
from the original Chrysler Hemi of the 60's, some
Top Alcohol Hydros are powered by an all-aluminum
hybrid V-8 engine. The "Toxic Rocket"
is powered by alcohol for fuel. The intake systems
are very sophisticated. They use a device called
a supercharger. The supercharger is like an air
compressor which forces air into the engine, in
turn produces the tremendous horsepower created
by these engines. A Top Alcohol Hydro can cover
1320 feet in 5.6 seconds at speeds around 215
MPH.
At a typical race event, each competitor
is given the opportunity to qualify a minimum
of two times in their perspective class on Friday
& Saturday. A qualifying pass is a timed run
down the course. The top qualifiers are then assigned
an opponent within their class for Sunday's eliminations.
The winner of each elimination run moves to the
next round and when only one competitor remains
he is claimed the winner.
Each competitor is given his/her
own space in the pit area (this area is where
the boats are assigned to perform repairs and
maintenance, during an event). Here spectators
can view the crews while they perform work on
the boats, as well as the see the team's transports,
buy racing apparel, and talk with drivers.
