racing Rules


GENERAL RACING RULES

1. GENERAL
These rules are General Racing Rules and will apply to all types of model boat racing. Further rules which apply to the various types of racing, i.e. Oval, Endurance, are listed separately.
Where a rule for a specific type of racing is at variance with these rules, the specific rule will apply.

2. DEFINITIONS
Monoplane is a hull that runs on one continuous, wetted surface while under full plane.

Deep Vee is a monoplane hull where the angle of the ‘V’ bottom must be 15 deg. minimum and 28 deg. maximum at transom from chine to keel.
Angle at bottom of keel line in the centre of the boat must be a ‘V’ extending forward from transom to the bow with no flat pads allowed at keel line.
Spacing of strakes from keel to chine must be equal and not vary more than 25%. e.g. strakes cannot be placed together at the keel to form a flat running pad. They must be parallel to the keel for at least two-thirds of the hull length.

Hydroplane is a hull that rides on two or more wetted surfaces while under full plane.

Tunnel bull is a hull that has its major ride surfaces spaced apart, parallel with its centre line. Such ride surfaces forming more than 80% of the hull length

3. SAFETY
There will be no running by anybody in the pit areas.
Covered footwear must be worn by all competitors and their pit crew at all times while they are in the controlled model boating area.
Smoking is prohibited to all competitors and their pit crew at all times while they are in the controlled model boating area.
The Contest Director or other appointed person must outline any site hazards to the competitors prior to the start. Items such as launching and tuning areas, racing rules and rescue boat requirements etc will be covered.

4. CLASSES
Classes shall be determined by engine swept volume measured in or parts of a cubic cm and shall be as described below.
Class - 3 Up to 3.5cc glow engine
Class – 2 3.51cc to 7.509cc glow engine
Class – 1 10.00cc to 35cc glow or petrol
1/8th Scale Hydro 10.9cc max
Sport 45 7.509cc max
Electric classes As per MMPBC class rules

5. NOISE
All Boats must comply with a maximum of 87dba at 10m, measured 1m above water level and at right angles to the direction of travel of the boat being tested. Boats will ask to be tested from time to time.
For 100 m speed events or where it is considered too dangerous to do a noise check at 10rn, noise levels shall not exceed 81dba at a distance of 20 m.
Any driver whose silencer unit becomes noisy due to damage or breakage of any kind,
shall immediately bring the boat into the pit area and shall repair it to the satisfaction of the judge before resuming the race.

6. HULLS
Any external projections, lifting foils, exhaust pipes. etc., projecting beyond the sides of the hull proper which in the opinion of the CD may be liable to cause interference or damage to other boats shall not be permitted.
All boats must be propelled by water reaction.
Only one hull per event may be entered.

7. SCRUTINEERING
Scrutineering may be carried out before each boat is run each day by a suitable person (s) appointed by the Contest Director.
The items to be checked are
1. Radio Frequency
2. Radio range (must extend 9m with the Tx aerial retracted).
3. Radio boxes should be free of condensation.
4. Rudder and turn fins should be kick up type where possible.
5. General overall mechanical condition, e.g., rudder post slop, linkage slop, throttle
linkages, engine and radio box mounting etc.
6. Failsafe operation to be checked if fitted.

Any problems will be reported to the Contest Director who may carry out other types of checks and if not satisfied, the boat can be put off the water until a suitable repair is made.
A failed 9m radio test will require an aerial up test of l00m (paced) to verify control over the model

8. RADIO
Radio control units must be such that a driver has control over speed and direction of the boat. The channel separation shall be such that there is no interference between channels.
Competitors using split frequencies maybe required to change crystals if a frequency clash occurs, this will be at the Contest Directors discretion.

When entering any event at any regatta sanctioned by the NZMPBA or SUHA, an alternative frequency MUST accompany the preferred frequency. A maximum of 15 minutes will be allowed for a competitor to change crystals.
It is highly recommended that a throttle failsafe be fitted to all boats. If fitted the failsafe must close the throttle fully when loss of signal occurs.

9. STARTING PROCEDURE
The Contest Director shall be the sole judge of the starting procedures and cut off times for launching of boats, and indicate which boats have broken the start.

10. PENALTIES

Hitting an announced dead boat Disqualification from heat
Hitting rescue boat Disqualification from event
Hitting course buoy $5.00 penalty
Not slowing down around dead boat Loss of points from that heat
No pitman while running $5.00 penalty
Continuation of running no pitman Loss of points for that race day

11. PROTESTS
Protests may be registered during a race and up to fifteen minutes after the conclusion of the race. A fee of five dollars must be deposited to the Club Captain or Secretary at the time of registration of the protest, this fee being refunded if the protest is upheld.
Protests against warnings or disqualifications issued during a race will not be entertained. The decisions of judges will be final and binding and no correspondence will be entered into at any time.
Protests will be heard by a Committee comprising of the Club Captain, Contest Director and two Senior Members present. Person who protested must be excluded from the Committee.
The Committee will decide and order a re-run of the race or award appropriate points as seen fit to remedy the situation.

12. RESCUE
Rescues will not take place during oval racing unless there is a danger of loss of boat or equipment through sinking. In this case the race will be stopped and re-run. Only boats running at the time of the stoppage can restart.
Rescues will take place during endurance racing, in which case the rescue boat has the right of way at all times. The rescue boat must take the shortest route possible across the racing lanes of the course and must not cross the pit lane.
In all cases the rescued boat will be returned to a designated area and pulled out of the water.
No person may enter the water during a race.
The Rescue Boat Must Be Stopped (Taken Out Of Gear) While Retrieving A Boat.

13. DRIVER ASSISTANCE
Each competitor must have one qualified pit person to assist at all times while his boat is on the water (including practice).
Only the driver may operate the transmitter while the boat is on the water during a race. In the event of an emergency the pit person may operate the transmitter to bring the boat back to the pit, but any such lap so completed will not score.
No driver will leave the drivers stand at any time during a race or abandon his transmitter while his boat is still running on the water.
