Section 3

Principal rules, personal and technical rules


Principal rules

  • Competitions where these rules apply

    • CMBC rules apply to all CMBC sanctioned events. A national or non-club event held at the CMBC facility, would not necessarily be a CMBC sanctioned event, which would allow for different rules to those of CMBC, being applicable in such instances.

 

  • Entry fees, membership fees and special levies

    • CMBC race entry fee will be determined by the CMBC committee annually and published on www.cmbc.co.za

    • CMBC membership fee will be determined by the CMBC committee annually and published on www.cmbc.co.za

    • New members who affiliate during the year will pay proportional affiliation fees as determined by the committee.

 

  • Protest fees

    • The protest fee at all official CMBC events is R200.00 cash.

 

Personal rules

  • Age groups

    • At CMBC events the competitors are divided into two age groups – Juniors and Seniors. This rule will only apply if there are sufficient Junior pilots. Junior pilots will be allowed to race with senior pilots in any class but only as approved beforehand by the committee. The committee will make their decision on the basis of a Junior members experience and competence in controlling his boat in competition conditions.

    • A Junior is someone who in the year of competition is not older than 18 years. (Someone is no longer a Junior if they have their 19th birthday in the year of the event.)

  • Competitor Registration on race days

    • In order to compete in a club event, the pilot’s entry fee is payable to Race control at registration. All non-member pilots have to pay the non-member-entry/race fees as specified on the club website, in order to participate on club race-days.

    • By entering the competition, the pilot accepts these rules and indemnifies CMBC or the hosting club or association from any claims whatsoever. All pilots must sign an indemnity form before their first race.

 

  • Minimum / Maximum competitors per heat

    • Offshore: 1 boat minimum, 12 boats maximum

    • Hydro/Rigger: 1 boat minimum, 6 boats maximum

    • Gas F1: 1 boat minimum, 12 boats maximum

    • Nitro F1: 1 boat minimum, 12 boats maximum

 

  • Multiple groups per class per race day

    • If the entries exceed the maximum boats allowed per class, the pilots will be divided into 2 or more groups. The pilots in each group will be determined by a ‘lottery’ draw.

 

  • Any number of entries per class per race day, (even if just one entry is received), will be entitled to race in the maximum number of heats allowed per class!

    • Race control is currently applying a scoring rule that allows for stopping a heat at any point if a specific pilot is (by whatever circumstance) already the last pilot racing in a heat through retirements by all other boats in that heat, or because that pilot was the only entry in that class heat. Such a ‘winner’ will then be awarded 1st place points score for the day, and be credited with the historic average winning lap score for that class. This could mean that such a pilot will receive the above point score and lap score, even if he has only completed just a few laps in that heat!

 

  • Assistants and substitution of the competitor

    • It is preferred that in all classes a pilot will have an assistant. This will be to assist in launching and retrieving the boat.

    • The assistant is allowed to help the pilot in the preparation for the start, during and until the finish of the race.

    • The assistant is not allowed to control the boat at any time that the boat is on the water unless the competitor becomes incapable of doing so. The assistant may stand behind the pilot on the driver’s stand during the heat but may not interfere with, or talk to, or hinder any of the pilots.

    • Under no circumstance may any pilot (or pilot’s assistant) on the drivers stand argue with, or make any aggressive comments towards another pilot or assistant on the stand, during milling time or the duration of a heat. Pilots must reserve such behavior for discussion after the heat is completed and preferably in the presence of race control.

    • Substitution of the competitor is not allowed during the race.

 

  • Heat duration

    • Heat duration is specific to each class as specified below:

    • Stock & Modified Gas Catamaran, Stock Gas Mono, Gas F1 Inboard:

      • 5 x Heats of 5 minutes each.

    • Mod. Gas Mono:

      • 4 x Heats of 8 minutes each.

    • F1 Outboard Tunnel Nitro:

      • 5 x Heats of 5 minutes each.

    • Gas Hydroplane/Outriggers:

      • 5 x Heats of 3 minutes each.

 


Technical rules

  • Propulsion of models and fuels

    • Only internal combustion motors are allowed. Jet engines and other forms of non-standard propulsion are not allowed.

 

  • Fuel

    • Pilots can either use a methanol/nitro/oil mixture, or pump fuel/oil mixture as prescribed by the class. The percentages in the mixture, and the octane of the pump fuel is at the pilot’s discretion up to class limits as specified below.

    • All nitro engines:

      • Must be a methanol / oil mixture, with or without Nitro

    • All Gas engines:

      • Must be a petrol / oil mixture. Maximum octane allowed is 110. No nitro or N.O.S. allowed

 

  • Noise level reduction rules (Also see Section 9 for measurement procedures)

    • All internal combustion engines must be equipped with devices to reduce noise levels i.e. silencer and/or cover.

    • The maximum decibels allowed is 95 dB/A. (As measured in accordance with the procedures detailed further on in this rule book.)

    • After a boat is checked by the decibel meter for noise, the pilot must be warned and advised immediately if the boat exceeds 95 decibels, and he will also be informed that the boat will have to be re-checked at the next race meeting. He will be permitted to continue racing on this day.

    • If at the next race meeting, the boat still exceeds 95 decibels, the pilot will be instructed to immediately remove his boat from the dam, and not restart the engine again unless he has fitted new or additional silencing and wishes to have the boat re-tested. Such a re-test will be done at the discretion and timing of the senior race controller/committee members on duty at the time.

    • If that specific boat is retested on the same day, and again fails to achieve a reading within the 95 dB/A, the pilot will not be permitted to compete with that boat for the rest of the race meeting. This applies to subsequent race meetings as well, until the boat is again tested and complies with the 95 decibel maximum.

    • The noise level rules will be applicable to all boaters using the dam facilities at any time i.e. during a race, at free practice or at fun days.

    • If at any time, a silencer or tuned-pipe is lost or becomes loose resulting in a dramatic increase in the noise level of that boat, race control will be permitted to instruct that pilot to bring his boat in to the retrieval area on that lap and to stop the engine. •

 

  • Application and use of radio control equipment and frequency control

    • During official events, only digital and proportional operated radio control equipment is allowed. The radio control must be capable of working within 20 kHz, which for example, would allow 12 models in the 27 MHz band. The use of any other frequency bands may be possible.

    • The 35 MHz band is reserved for the exclusive use of model airplanes and will therefore not be allowed.

    • At the start of the season/first race meeting all boats must be registered. A frequency and a race number will be allocated to each boat for the year.

    • Radio/frequency checks will be carried out prior to the start of every first heat to prevent clashes. When someone has a problem the race will be run if the problem can’t be rectified immediately.

    • When competitors are not racing in the current heat, radios may not be switched on within 1000 meters of the competition area. (Not even in the hot pit areas) Competitors who disobey this rule will be disqualified from that day’s racing and could lose points.

 

  • Transponders and their use for lap scoring

Due to equipment failure, the transponder system is currently disabled at CMBC until further notice. Therefore all rules related to the use of transponders, are not currently applicable.

    • The use of computerized race control technology has been introduced at CMBC and requires that all boats are fitted with CMBC-specified transponders, so that the boat’s progress in terms of completed laps and timing can be recorded in real time in the race control computer system. It is the responsibility of all pilots to purchase these transponders from CMBC and any new members are encouraged to do so as soon as possible after joining. Relevant information is available from any committee member.

    • NOTE! The 7-digit transponder number must be clearly displayed anywhere on the deck of the boat with the numbers being at least 10mm high.

 

  • Buoys (Dimensions, construction and anchorage)

    • The race course will be marked by buoys, yellow, red, orange or white in colour.

    • The shape of the buoys can be cylindrical, round, square or rectangular. The buoys will be anchored so that they are at right angles to the water surface.

    • The buoys must be between 300mm and 400mm in length and diameter.

    • Buoys must be made of materials such as polystyrene, rubber, cork, compressed high density foam or any other material that will minimize damage if a boat collides with it.

 

  • Hot Pit Area (construction and materials)

    • The Hot Pit area must provide adequate space for the competitors and their models and assistants. Any obstructions which could endanger the safety of the competitors and the models must be avoided.

    • All boats may at all times only be started in the Hot Pit areas. Then launched and retrieved from the launch area.

    • Access to the launch area should be clear. Visitors, family members, and particularly children, must not be allowed at the entrance to, or in the hot-pits. Any member witnessing children or unauthorized persons in the hot pits area, have the right (and responsibility) to remove such individuals!

    • All footwear of a Slip-on/slip-in fashion, with or without straps, is banned!

    • Only tekkies, or shoes with laces, or gumboots must be worn.

    • No Rockeys/Crogs/Slip slops. Shoes must be worn at all times, no bare feet allowed. If at the committee discretion your foot wear is not appropriate you will be asked to change and no further discussions would be entertained.

    • Steps to launching area should provide for separate ‘walk down’ and ‘walk up’ lanes. Steps closest to buoy 1 is the ‘walk up’ lane and the steps closest to driver’s stand is the ‘walk down’ lane.

 

  • Safety regulations

    • All boats must have sufficient floatation (pool noodle etc) as to facilitate the boat to float above the water line when filled with water

    • All boat motors must be able to be cut with the radio equipment. (By activation of switches or levers on the radio transmitter.)

    • All competitors must wear appropriate foot gear which is of a non-slip form. Sandals or CROCS style slip on foot wear is not allowed. All footwear of a Slip-on/slip-in fashion, with or without straps, is banned!

    • Only tekkies, or shoes with laces, or gumboots must be worn.

    • No Rockeys/Crogs/Slip slops. Shoes must be worn at all times, no bare feet allowed. If at the committee discretion your foot wear is not appropriate you will be asked to change and no further discussions would be entertained.

    • All personal boat stands/mountings, in the pit areas, must be of a sturdy nature and even though engines may not be started in the pit areas, such stands should preferably have some form of propeller protection.

    • NOTE ! IN THE INTEREST OF SAFETY, THE CMBC COMMITTEE HAS DECIDED TO MAKE IT A HARD-AND-FAST RULE THAT NO BOAT ENGINES ARE PERMITTED TO BE STARTED IN THE PIT AREAS EVEN WITH THE PROP REMOVED, AND THAT ANY ENGINES MAY ONLY BE STARTED IN THE HOT PITS AREAS.

      HOWEVER, NO BOATS THAT ARE NOT IN THE CURRENT HEAT, MAY BE STARTED ANYWHERE UNTIL THE MILLING TIME FOR THAT HEAT IS COMPLETED. ENGINES MAY THEN BE STARTED IN THE HOT PITS AREA, BUT WITHOUT TX CONTROL. I.E. ONLY WITH ACTIVATION OF THE THROTTLE LEVER BY HAND.

      THE PENALTY FOR TRANGRESSING THE ABOVE RULES WILL BE AT RACE-CONTROLS DISCRESSION, BUT COULD INCLUDE THE PENALTY OF LOOSING 100 POINTS FROM HEATS TOTAL POINTS-SCORE THAT COUNT FOR THAT DAY.

 

Sport Rules

 

  • The competition area

    • The competition site, especially the racing water and the surrounding area, should be selected by the organizers to give the competitors the best possible conditions to achieve good results.

    • The organizers will ensure that adequate safety measures are in place to protect competitors, officials and spectators from possible danger.

    • The competition site, the racing water and the surrounding area must be checked prior to the race by the race officials. In the event of complaints from the competitors, the organizers must attempt to correct the fault immediately.

    • The competition site and the race water must not be contaminated by mineral oils, grease and other poisonous substances. No competitor or assistant may discharge or dump any fuel into the racing water.

    • Failure to comply with this rule by a competitor will result in disqualification from the competition. Lodging a protest will not be entertained at all.

 

  • Allowed number of boats entered per class by a pilot, entry possibilities and race condition of the models

    • A pilot can register two models per class and will only pay entry fees for the second boat if and when he uses it in a race-heat.

    • The transponder number of the second boat must also be provided to race control at the time of registration so that the transponder numbers for both boats will be linked to the pilot’s name in that class, in the computer system. This will provide for a seamless transition for the system to collate the scoring for that pilot even if he changes to the second boat after heat number two and completes racing heat 3 and 4 with the second boat.

    • Payment for racing the 2nd boat must be made before it is brought to the hot pits.

    • In the event of the second boat having a different frequency the pilot must also register this frequency at the time of race entry.

    • It is the choice of the pilot which of the two models he will use for a race/heat. The second model does not have to be of the same design or paint scheme as the first model, but must clearly qualify as being of the same class.

    • The second boat must carry the same race number as the first boat.

    • Only one model can be brought onto the hot pit area. In the event of a breakdown during a heat, the pilot will not be allowed to use the second model in that same heat. It may only be used during the next heat.

 

  • Re-run of a race

    • There is no right to a re-run if a model is damaged during a heat or if a propeller is caught by a foreign object like weeds, fishing line etc. or if radio equipment malfunctions.

    • A heat can be repeated when timing or lap counting fails, or after disruption caused by drifting buoys etc.

    • Or at the discretion of the Race Organizer.

 

  • Registration of competitors and models, scrutiny of boats

    • Race Control is entitled to request that each competitor registers their models including any spare models and their radio equipment, within the registration time prior to the race event starting.

    • The competitors must show their boats for scrutinizing, if requested to do so.

 

  • Calling time (time allowed to get ready)

    • The calling time is two minutes. Within this time, the start controller will call the class/heat type by name to take their positions on the hot pit area.

    • If the competitor does not take their position on the hot pit area with their model within the calling time, the competitor loses their right to start the race

 

  • Interruption or suspension of the competition, or cancellation of a complete raceday!

    • An interruption, delay or cancellation of the complete competition can only be decided on, and announced, by the chief judge/race controller/organiser.

    • An interruption or delay of a heat at the starting jetty can only be decided by the chief judge/race controller/organiser.

    • Cancellation of a complete race day, due to weather/forecasts, or any other potentially disruptive aspect, is permitted by the committee. Such a decision will always be made in the interest of the club membership, and their and the club’s equipment, and will be communicated to all members via the CMBC WhatsApp chat-group facility. Such decisions will be made within the best available time frame, but could include being made a day (or days), prior to the race day , or at the start of proceedings of the actual race day, or even at some point during a race day. The full prerogative for such a decision is held by the committee and will be binding irrespective of how any such disruptive aspects materialize on the actual race day.

 

CMBC protest policy

 

  • Principal rules

    • A protest can only be lodged if the competitor is convinced that their race result has been compromised by one or more of the following:

      • another competitor piloting his boat in contravention of the racing rules.

      • another competitor having a boat that does not conform to class rules.

      • a decision, act or omission made by one of the competition officials.

    • The final results, placing, the awarding of titles, medals and honorary awards can only take place after all lodged protests have been resolved.

    • The decision of the jury is final. Appeals are not accepted.

 

  • Lodging of protests

    • Each protest must be verbally reported to the chief judge immediately upon observation of the alleged infringement, either by the pilot or his assistant.

    • The protest must be lodged in writing to the chief judge within half an hour after the race in which the incident occurred.

    • The lodging of a protest does not necessarily exclude the accuser or the accused competitor from further participation in the day’s competition. However this will be subject to the committee’s judgment on the severity and type of offence.

      Some protests may require that the judgment, and/or ruling, can only be made at the end of the race day. If such a protest involves having to scrutinize equipment such as a boat or a transmitter or fuel etc., then such identified equipment may not be tampered with, or removed from the pit area, specifically if the accused pilot wants to leave the race site and wishes to take his equipment with him. This would then clearly represent a situation where the accused pilot wants to remove the possibly errant equipment before a judgment can be made by the race control / committee officials.

      If such an accused pilot ignores the above ruling, and leaves the race site with his all his equipment, prior to the judgment of the protest, he will automatically be deemed to be guilty of the relevant offence and will receive the full appropriate penalty.

    • If after a verbally lodged protest measures are taken to correct the situation, a written protest will not be necessary.

    • If the competitor is still not satisfied, he may proceed with the written protest and pay the protest fee.

    • The written protest must contain the following:

      • Grounds of the protest (respective rules, regulations, acts and where to find them)

      • Time, place, a precise description of the incident, the reason for the protest, possibly including drawings and other evidence.

      • Statements and names of witnesses who were involved in the incident and who are willing to truthfully answer questions regarding the protest.

      • Statement containing the name of the official to whom the verbal protest was lodged, the time when it was lodged, and by whom it was lodged.

    • The protest must be signed by the competitor.

    • The protest fee must be paid in cash, when the written protest is lodged, or the protest will be null and void.

 

  • Handling of protest

    • The jury has to consider an officially lodged protest for which the protest fee has been paid, and give a decision.

    • The jury will consist of the chief judge, the competitions manager and one other committee member.

    • The competitor who has lodged the protest and the person against whom the protest negotiations are conducted, have the right to attend the hearing without voting rights.

    • For the protest negotiations the jury can call further witnesses involved in the incident who must give a truthful account.

    • The decision given by the competition management on the outcome of the protest will be announced to the affected competitors. If the protest is successful, the protest fee will be returned to the competitor. If the protest fails, the protest fee will remain with the organizer.

 

  • If the protest is successful and the person against whom the protest was conducted is found guilty of breaking racing rules, the penalties will be imposed against the accused competitor
