2. All races will be run by the procedures listed in the race flier for that particular event.
3. Only the driver(s) signed on original entry prior to the close of registration will be

eliminator boat per event.
5. Any driver failing to answer roll call at Driver’s Meeting may be disqualified. Only
owners and drivers will be allowed at Driver’s Meeting.
6. All boat numbers must be legible from three hundred feet and be 10” high with a
minimum 2” brush stroke, in contrasting color on both sides of boat.

only one fires, he/she will be declared the winner after completion of a legal single.
2010 NJBA Rulebook 20
a. A legal single only occurs when a boat’s competition does not show, or
does not cross the starting line beam within 5 seconds of the green
light.
b. Any boat in competition that cannot start the engine and cross the start line
beam under the power of the engine within 5 seconds of the green light, will
be disqualified.
c. Lights will be interpreted as follows:
(1) Blinking Yellow…………Start Motor
(2) Yellow……………………Stage
(3) Green…………………….Go
(4) Red……………………….Stop
NEVER PROCEED ON A RED LIGHT!
CATEGORY
1. First or Worse – The primary objective of each category race is to have one winner
and one loser with the Race Director having full responsibility on cases involving dual
disqualifications. Should a double rule infraction occur on the same run, the driver
committing the major infraction will be eliminated. The other driver with the lesser
offense will be reinstated.
2. Red Light – A red light on a bye run or legal single run will not eliminate a boat from
competition.
3. Dual Red Lights – When both boats in competition red light, the boat that red lights
the least will be declared the winner.
4. Boats are not required to make a bye run.
5. Where a three (3) boat field does not exist, a step-up is allowed to the next higher
class or next higher cubic inch class in which the boat is legal. These boats must
also be legal for the class for which they are claiming points.
6. All category class winners may be P&G inspected.
GASOLINE
Gasoline, as defined, is a mixture of hydrocarbons. Gasoline is a good electrical
insulator, or dielectric, and its relative effectiveness as an insulator is represented by its dielectric
constant. The average D.C. for the hydrocarbons, which comprise gasoline, is 2.025. This is
defined as a reading of 0 with the NJBA fuel meter. To compensate for possible temperature
differences of gasoline, which cause slight variations of the D.C., the maximum acceptable meter
reading is +1, with 0 as the reference reading. A gasoline which has a D.C. greater than 2.3 will
cause the meter reading to be outside of this range. The addition of compounds containing
nitrogen and/or oxygen may produce a mixture of D.C. greater than 2.3. Most gasolines meet
these criteria. It is recommended that unknown gasoline be checked before use in competition.
PAIRING
1. Pairing for the first round eliminations will be based on the ET’s of the field. Boats will
be matched in a 16-boat field.
2. If there is an uneven field, in the first round, the #1 boat (quickest time) will be
awarded the bye.
3. The bye boat need not report to staging for a run if he so chooses. The boat will
receive the points for that round.
4. The balance of the race program will be run by the ladder system.
5. At the time of roll call, should a driver not answer or should he declare withdrawal
from the program, the seventeenth (17th) qualifying boat shall be inserted in the field,
and the entire category re-paired.
6. NJBA category drag classes will consist of a maximum of any 16-boat field. Bracket
classes have no limit.
2010 NJBA Rulebook 21
7. In the event that any category class does not receive a full round of qualifying, the
boats in that class will be paired by drawing. Anyone missing a round of qualifying
due to their own negligence, or mechanical failure will not be considered as causing
the class to be incomplete.
a. Upon the discretion of the Race Committee, categories in this situation may
not be limited to their usual field.
b. Qualifying points will not be awarded to the number 1 and 2 qualifiers when
boats are paired by a drawing.
8. In the event that all boats entered in bracket classes do not receive a qualifying run,
brackets with boats that did not receive a run will be paired by a drawing. Anyone

a. Qualifying points will not be awarded to the number 1 and 2 qualifiers when
boats are paired by a drawing.
9. After the completion of qualifying, there will be thirty (30) minutes to declare into a
bracket other than the one your qualifying ET places you, or on your registration form.

10. If a qualified boat declares broke or is disqualified on Saturday, the remaining
qualified boats will be re-paired.
11. If you are aware that an illegal boat has entered your class, you must inform the

program.
2. If a bye boat situation exists, the bye boat will be ranked on the basis of the ET that
established his bye run for that round.
3. The ranking for a bye boat shall be the ET recorded from the previous round.
4. At no time shall the ET of an eliminated boat be used in determining the winner or
runner-up.
5. If the first round of a category is not completed, the winner and runner-up will be the
boats with the fastest and next fastest ET in qualifying.
6. If any remaining boat in a class does not receive an ET, the winner and runner-up in
that class only will be declared by MPH.
RECORDS
1. NJBA will recognize speed and ET records for jet drive or prop drive boats running

If the clocked time of the back-up run exceeds the record leg by no more than
1%, the faster time will be considered a potential new record. In the event the
back-up run exceeds the record leg by more than 1%, the faster run may be
considered a potential record leg, and must be backed up by another run
within 1%, time permitting. If this is not accomplished, the original time will
stand as being backed up.
5. Any NJBA member claiming a new record must submit written proof to the Records
Chairperson supporting his claim at a race site. Claim to include all pertinent data, as
