A. General safety regulation valid for all Classes


The following rules are valid for all classes equipped with electric motors:



All boats must be equipped with a so-called emergency circuit breaker according to drawing (Appendix B No. 1). The emergency circuit breaker must be connected in such a way that in case of emergency, the competitor, start assistant, recovery boat or any other person can interrupt the Power between motor and batteries.

If for some reason, the people in the rescue boat or any other person cannot disconnect the kill switch, that particular boat is taken out of the race and disqualified for that heat


Emergency circuit breakers may not be mounted on lids or other removable parts of the boats. The circuit breaker may be mounted on either side. The loop must be made out of red cable. With effect from the 01.01.2005 no other sort of emergency circuit breakers are permitted. At World Championships the emergency circuit breakers will be checked at the registration.

If during the registration it is noted that the emergency circuit breaker does not correspond to the regulations, an alteration is not allowed. The competitor is not allowed to compete. Each National Organisation is requested to pay attention that the circuit breaker is correctly installed.

Only approved version of the circuit breaker, as shown in Annex A nr1,2 and 3 are permitted.



All boats must be equipped with a kill switch for the Radio control equipment that is operated from the outside of the boat. If the receiver is supplied with a so-called BEC system, then the competitor has to prove this to the starting judge. Switches under sliding lids are not permitted.



The hulls of boats in the classes FSRE, Eco, Mini Eco, Eco Expert, Eco Team, Mini Eco Team, Mono/Hydro must have a well recognizable colour. (This well recognizable colour must amount at least 1/3 of the bottom of the hull). This should contribute to the clear recognition of a capsized model. Dark, for example black, deep-blue or similar colours are not permitted.



Should the recovery boat have to drive onto the course during a heat, the recovery boat always has priority of way. The recovery boat is to be passed at slow speed. Any danger for the recovery boat and its occupants is absolutely to be avoided. If the recovery boat is touched by a boat during a heat this accounts to an automatic Disqualification of the competitor. With an accidental touch a 1 lap penalty can occur (this lies in the judgement of the starting judge).

Should the recovery boat run over or against a dead boat, no penalty is given.




Only Nickel Metal Hybrid, Lipo or LiFePo batteries are permitted as a propulsion pack.

Dimensions and weight restrictions are fixed in each class rules and regulations. Turning down cells on a lathe to achieve weight relief is not permitted. The nominal voltage of a single NiMh (max. height of the cell with expansions 45 mm) cell may not exceed 1.2 v.

For Lipo the nominal voltage of a single cell cannot exceed 4,23v and for LiFePo not higher then 3,80v per cell. Overcharging of batteries is not allowed. This is the case when at the voltage check a voltage is measured higher then the maximum voltage multiplied by the number of cells used. If this is the case, the competitor has over charged the cells,

or used an inappropriate charge mode in order to obtain a higher voltage. The competitor is then disqualified. The competitor has to state the type and number of cells used to the people in charge of weighing and measuring batteries.

Pressing Lipocells or NiMh cells that have "ballooned" in any device to press them back into their original shape and size, whether it be before use, after charging or after a race in-or outside of a boat is strictly forbidden out of a safety aspect. Batteries that have "ballooned" should not be used anymore for safety reasons. On a second offense, the competitor will be disqualified.

The disposal of batteries of any kind in non approved containers on the grounds or in the wild is strictly forbidden. On a second offense the offender will be expelled from the whole event. The Organizer has to make sure proper approved containers are available for the disposal of batteries.



Juniors up to the age of 12 may only compete in the different Eco classes, Mono1 and Hydro 1. (this does not apply for the classes F1E,and F3).

For as long as a class is run for Seniors, Juniors can participate. Even if there are not enough Junior participants/represented countrys. In the event not enough Junior participants are there to fill up a series in the group racing classes, they will run along side with Seniors.



Juniors up to the age of 12 may not be used as start assistants for safety reasons.



The points 4 and 7 also apply for those classes with internal combustion engines.



At World and Continental Championships the Organizers must have a Civil Liability Insurance towards Naviga. This insurance must cover personal and 3rd party insurance.



On all racing platforms as well as in the Pit area, adequate fire protection material has to be present, fire extinguisher, fire blankets and buckets of dry sand, Each competitor is responsible for the safe transport and handling of their batteries, This also applies for their residence during their stay as on the grounds. On the grounds batteries are to be charged in either Lipo bags or Lipo cases, All competitors are advised to bring their own fire blanket in case of emergency. The Organizer as well as Naviga cannot be held responsible for any injuries or damages.




Heating of Lipo batteries is allowed up to 40 degrees Celsius. Heating of batteries is only allowed in solid state heating cases.




At a World Championship or Continental Championship event, Medical Personal has to be present at all times, every race platform must have a First Aid kit available. Should these requirements as well as any other safety precaution not be met by the Organizer, the event will be interrupted by the Naviga representant, and if not corrected even stopped.



The starting judge is entitled to, if the regulations are not abided by, exclude the competitors from the competition or heat. The correct function of the emergency circuit breakers will be checked at the registration and before every heat by the starting judge.

The colour of the Hull is checked at the registration, if no registration occurs, the starting judge inspects the hull before every heat.



A protest against the General safety regulation is not possible.



Every competitor agrees to have his boat recovered after it sank. At any event, the Organizers have to make sure a diver can salvage a sank boat. Diving for a lost boat is to be done during the lunch break or at the end of that day's races. The cost for such a recovery (i.e. the cost of a diver) is at the expense of the competitor.

As long as the diver is busy there is to be absolutely NO driving boats anywhere on the lake.

Please note!!

In the classes Eco Expert, Mini-Eco, Mono / Hydro, a recovery of dead in the water boats takes place only after a heat, except if a boat looks like it is going to sink. If a boat is recovered outside the area of the landing stage during a heat, it may not be used in this heat any more.



B.          General Guidelines


Requirements for start area


For each participant in heatracing, a 1,5m space should be available. In the classes F1 and F3 this space should be at least 3m. The width of the platform should be at least 1 meter. In Eco,Hydro, Mono, Eco Team and FSRE each racer takes position according to his race number. Positioning is done from left to right. If more than 1 heat is run in a class, the positioning will be inverted at each heat, in other words in Heat 1 the starting position number 1 is on the left and in the second heat the starting position 1 will be on the right.

On every Race Platform a first aid kit, a fire extinguisher, fire blanket and bucket of dry sand has to be present. It is up to the Platform Judge to verify the presence of these items.

There is to be no racing until these items are accounted for.

The access to the racing platform, in particular the path leading up to it should be safe and without any obstructions. The surface of the platform has to be so that tripping or sliding is impossible, even in wet conditions. The platform should also be separated from spectators in such a way the competitors are not hindered by any spectators.

The racing platform has to be solid and not shift or move out of place. The surface of the platform cannot be higher than 250mm above the surface of the water. Floating platforms have to be fixed in such a way, they cannot move in any direction.

The Organizer has to provide 2 boats for recovery of dead models (1 on each side of the Startline). At a World or Continental Championship these boats have to be equiped with a motor (electric). The rescue boats have to be protected (preferably with foam) adequately. At all times the rescue boat has to be manned by at least 2 adults, knowledgeable persons appointed by the Organizer. In the event of difficult recovery, like for instance in the F1 class, the start helper can accompany the rescue boat in order to safely retrieve the dead boat. The rescue boats have to be equipped with life jackets.

Recovery boats that can easily be damaged ( Zodiac type, inflatable boats) are not permitted.

Retrieving of dead boats is under the supervision of the Starting Judge, in such a way that retrieving is done in the shortest of time without hindering or damaging other boats, in a way that everyone is treated the same. The rescue boat will proceed in a direct line towards the dead boat(s) and always has the right of way. Passing boats have to slow down and if needed move out of the way. Should any boat cause a threat to the rescue boat, the Platform Judge can sanction the participant by deducting a lap and in case of repeat a red card. In the event of an avoidable collision with the rescue boat, the Platform Judge must sanction with a red card (see safety regulations for this). For minor touching, or when this was unavoidable (for instance the rescue boat touches an idle boat) there is to be no penalty.

Dead boats are to be retrieved in order of their position on the race course. A boat that seems to be sinking is to be rescued first.


The following items must be present at the Race Platform:

1 digital weighing scale

1 digital volt meter

1 frequency scanner ( for supervision of radio frequencies)

1 computer for lap counting

Paper forms for manual counting (see annex C4)

3 digital stopwatches

1 software for lapcounting


Personel for the race platform


On a race platform in the classes Mono / Hydro, FSRE, Eco, Eco Team, F1 and F3 the following personnel had to be present:

1 Platform Judge (2 for Eco-team, in which case 1 of them is the head judge)

2 or 3 judges or experienced people to guard missed buoys

3 timekeepers in the classes F1 and F3

1 knowledgeable person to operate the lap counting computer



C.          Guidelines for participants


Age groups

Specified in General Rules


Participation to Worlds or European Championships:


Only persons affiliated to a Governing Body, known and recognized by Naviga and are aware of the Rules can participate at Worlds or European Championships. Their membership to their Governing Body should be at least from the year of participation and should still be active. All models used by the participant should comply with the rulebook.

With the validation of the Rules for Championships 2015, it is now possible for participants from countrys that joined Naviga on probation basis, to participate at Continental or World Championships.This is allowed only for 1 event, after that only by becomming a full member of Naviga



D.    General Technical Specs


Types of propulsion


Boats in the M section can be powered by electric or ic motors according to the specs of the class.


Fuel and refueling of models


Models in the class F1-V, equiped with glow plug motors, can use any fuel desired. The participant can have a refill botlle on the platform for refueling. It is not allowed to top up the bottle during ones time window.

The nitro amount in the fuel is limited to 25%. The Organizer has to verify when fuel is supplied to competitors, if this percentage is respected.



Loudness, loudness measurements and rules for measuring noise


IC motors must be equiped with a muffler which according to the General Rules, dampens the noise to the set level of 80 db/A. (for classes F1V and F3V)

The equipment used to measure the sound level had to be within a tolerance of +/-2,0 db/A and have to be according to IAC standards. The equipment should be provided by the Organizers. A certificate of accuracy by a recognized Authority has to be present.  This certificate has to be dated within a 1 year period of validity. Every measurement has to be done in such a way no doubt can excist over the accuracy of the measurement. Only personnel familiar with procedure, equipment can be appointed to make the measurements.

Procedure and equipment to be used can be found in Annex D6.



Race Order for Finals


In the folowing classes finals should be ran at International Events as well as in European and World Championships:

Eco, Mini Eco, Mono / Hydro, Mini Mono, Mini Hydro FSRE, Eco -Team, Mini Eco Team.

When the Finals are made up (look at Class Rules for this), starting order for the finals is decided. The person with the top qualifier result gets to choose his spot on the race platform for the final first. Next the second best chooses his spot and so on till all spots are asigned for.

In case no finals are held at least 3 heats per class should be run, it is advised however to run 4 heats per class of which the best 2 results then add up to make the final score.

If because of weather conditions or other unforseen events finals cannot be held, or not enough heats can be run to make up the addition of results, the best 2 results will make up the final score. If only 2 heats can be run, the best result will then count as final result.

This condition occurs when a race cannot be properly held without risking damage to both models and participants. (eg. Thunder storm, strong winds, heavy rainfall or snow and so on).  Team leaders (who have participants in the respective heats or finals),  the Head Judge, the Naviga representative as well as the Section Leader take a vote whether the event should take place or not. Should the vote be a tie, the Section Leader has the deciding vote.



Proper use of remote control equipment


At official Naviga events only remote controls with a maximum bandwith of 20kHz are to be used.

Radio systems working on 2.4GHz are also allowed.

The simultanious use of at least 8 sets has to be guaranteed. For safe use these radio controls should be working without interfering other equipment in a 20 mHz window. Fequencies in between the official channels are not allowed. Permission to use radio controls is governed by each individual country affiliated to Naviga. Also the frequency bands that can or cannot be used are to be defined by each individual countries' laws.

The Organizing Country has to anounce the frequency bands that can be used along with the invitation to the event. Also has to be stated if non-allowed frequency bands can be used for the duration of the event. Should such an exemption be granted, any cost this might bring is for the Organizers.

The Organizers cannot be held responsible for any trouble this might bring during the event, providing all the necessary information was provided with the invitation form.

For all radios and receivers it must be possible to change frequeny

or crystals swiftly.

All competitors in the classes FSRE, Mono/Hydro, and Eco must have 4 different frequencies available for their radio control. In the classes F1 and F3 at least 2 different frequencies must be there. (The frequencyto be used will be announced at the Registration).

If at the radio check some sort of interference by another competitor or other influence is noticed, in a way the safe operation of a model is not guaranteed, the competitor has to be given a chance to repeat the heat or trial, if it is technically and timewise possible.

It is technicaly not possibe (at this point) to prove interference from outside when using 2.4Ghz equipment. Should someone claim interference from another radio sytem, it is up to the competitor to prove this.



Time keeping


In all classes that are run for a certain amount of time, the time is to be kept up to 1/100th of a second.

Therefore only digital stopwatches are to be used.


Keeping time can be done either manually or electronically. For electronic time measurement only equipment that measures time automatically can be used as official time keeping. Electronic devices which are to be operated manually do not qualify as official timekeeping. Manual timekeeping by 3 timekeepers has to be done simultaniously with the electronic timekeeping for in case something should go wrong with the electronic timekeeping. In the event of failure to the electronic timekeeping system, the 3 timekeepers become the official racetimers.


F1 and F 3 classes

If time is kept manually this has to be done by 3 persons, procedure for this is as follows:

If 2 out of 3 stopwatches show the same time, the 3rd different time is cancelled.

If all 3 stopwatches show a different time, the time, more then 1/10th of a second different is cancelled. The official time will be then made up by adding the 2 stopwatches time and dividing that in 2. In this case the 3rd digit after the comma is adjusted to 0 or 5 if above/below.

Should any of the 3 stopwatches fail, the procedure as mentioned above is maintained.

If 2 or all 3 stopwatches fail, the run has to be redone. The Pontoon Judge will then declare when the run can be redone, taking all aspects into consideration.

The Pontoon Judge must verify the means of timekeeping for proper functionality before the start of each racing. The obtained results can only be cleared after the Pontoon Judge has given his consent.

The 3 timekeepers should be inline with the start/finish line behind one another, preferably on the platform.  If this is not possible, as close to the platform as possible.

During the run, the Pontoon Judge is to stay on the platform and overview the run.









The race course is to be marked with buoys. Each must be clearly visible in 2 colours (red/white). These coloured stripes must be vertical to the surface of the water.

The buoys must be cylindrical and made from, e.g. cork, Styrofoam or other materials that do not damage boats. Wires or any other form of connection cannot stick out of the buoys.The buoys are to be connected at least 300 mm under the surface of the water.



The following dimensions are to be respected:


Classes F1/F3/Eco:

Minimal diameter 100 mm, reaching vertically at least 100 mm and at most 200 mm out of the water. In the F3 class the distance between the buoys that make up the gates can be within a +/-5% range (measured from middle of buoy to the other buoy). The triangular course has to be anchored in place.( Steel cable or cable in a material that does not stretch)

Classes Mono/Hydro and FSRE:

Minimal diameter 200 mm, reaching vertically at least 200mm and at most 300mm out of

the water. The course has to be anchored in place.(Steel cable or cable in a material that

does not stretch.



Allowed models, how to be used and general state for racing


A competitor is allowed 2 models for each class he enters in. Both models have to be registered and marked. In case of repairs items from both models can be used as well a material such as propshaft, rudder, motor, speedcontroller. An extra hull or extra middle part or extra sponsons of a hydro cannot be used.

It is the competitor’s choice which of the 2 models he wants to use for a series or trial.

Both models can be brought to the preparation area, only 1 model is allowed however on the race platform. Once the competitor is on the race platform, he can no longer interchange models. During the time of the series or trial no changing of model is allowed as well. The second model can only be used in the following series or trial, even if the first model is damaged during the series/trial.

Any modell can be used in more then 1 class, ad long as the model meets the class  regulations.

If a model gets damaged during a series/trial, this is no ground for having the series/trial redone., even in the event of foreign influence like debries, waterplants, parts of buoys or others.

A demand to redo a series/trial can only be done in accordance with the Pontoon Judge under 1 of the following conditions:

Failure in timekeeping or rupture of transponder cables.

A proven case of radio interference.

If any buoy gets detached from the course, not by the participant who detached the buoy. (a boat gets stuck in a  buoy and the driver detaches the  buoy by throttling up for example).

Weather conditions deteriorate so bad between series, a fair competition is no longer possible.



Permanent registration numbers and race number shields


All models for the M class must have a permanent registration number. This permanent number is provided by the National Federation of the participant. The countries initials are a vital part of this number. This number must be unchangeable and be put firmly on the model. It cannot be placed on eg. A lid, the sponsons or any other removeable part ( see annex E1).

For hydro’s the permanent number can be on the outside, bottom part of the middle section.

2 models per class, per participant are allowed. Both models must have the same permanent registration number. The second model must also have the same race number as the first model. If the participant uses another model other than these 2, this leads to immediate disqualification for that class.

The numbers and letters that make up the registration number must be black on a white background. The height of the letters and numbers is set at 20mm (see annex E1). The class in which the model is used does not have to be stated on the model.



Race numbers


In all classes where laps are counted, all models must have a race number shield.

The dimensions for this shield are 80mm by 80mm. The shield should be made out of white none transparant material. The number on this shield must be in black with a height of 70mm and a width of at least 10mm. (see anex E2).

The number shield has to be mounted on or at the back of the boat, vertically and visible from both sides with at least 1 screw or bolt.

If the number is not clearly visible or transparant to the lapcounters, no counting will be done, no counting is done in case of a lost number shield. White areas with a racenumber painted on the boat are not allowed. In case of a lost number shield, the competitor has to stop at the race platform in the next lap. After replacement of the numbershield the competitor can carry on with the race.





Personel for the race platform look under general rules

Lapcounting is to be done by computer. Manual lapcounting must be done simultaniously on a form (see anex D3) for double security. Should the computer fail during a heat, the manual result will count. The time needed to finish the last lap will be called by the Pontoon Judge or delegated person and added to the manual timing sheet.


The Pontoon Judge will give the order to start the race and the clock directly from the platform. The signal to start the race will be given by whistle or by a computer generated beep. The end of the race will also be done by a whistle signal or computer beep. All models must finish the lap they were on at the time of the end signal. Boats that are on the race platform at the time of the end signal are not allowed to be put back in the water.

The run in time for the last lap is max 60 seconds.




Lapcounting with transponders.


At Worlds and European Championships, lap counting must be done by means of a Transponder system. Boats should be built so they can accept a transponder. In the invitation to the event, the use of a transponder system must be mentioned.

Each participant brings his/her own transponder(s). Organizers can, but are not obliged to, have rental transponders (to be rented for the event). In case of destruction or loss, the cost of this rental transponder is to be payed by the person who rented it. Power had to be supplied by either the receiver or a separate battery. The placement of the transponder in

the boat is not specified, but has to be in such a fashion it cannot move from its fixed placement.

Participants are themselves responsible for not properly installed transponders and any malfunction resulting from that.

Neither the Organiser nor Naviga will take any responsibilty for lost transponders.

Manual counting is done simultaniously (see above).



Registration of participants and their models


After Registration has closed, the organizers must publish and show the different lists of classes and its participants.

Refusals to register for any class are to be explained.

All models (max 2 boats per competitor per class) must be marked. If this mark is not on the boat at any start, the boat cannot participate. If for some reason this mark has been lost, the participant has to report this to the organizers immediately. Only boats in race ready condition are to be registered. A race number and working circuit breaker should be present at registration. Batteries and propellers are not checked at registration.

There is to be no start until at least 1 hour after the lists of classes and participants have been made public.



Order of classes


The order of starting (F1/F3) is decided by the Organizers or by draw of luck. For filling in the series, the following is to be guarded:

Participants from the same country are to be divided over different series.

Frequencies are to be picked so that the next up or down channel is not used in order to avoid interference.

If 2 or more race platforms are used, the Organizers may decide which frequencies are to be used on which platform.

The Technical Committee of Naviga advises the following use of frequencie channels for the different platforms:

F1 V:  27 Mhz: channels 1 -5

40 Mhz: channels 50, 52

41 Mhz: channels 401, 403

F1 E : 27 Mhz: channels 6 –9

40 Mhz: channels 54, 56

41 Mhz: channels 405, 406

F3 :    27 Mhz: channels 10 -17

40 Mhz: channels 51, 53, 92

41 Mhz: channels 400,402, 404

Eco, FSRE, Mono/Hydro: all the other channels in these frequencies:

27 Mhz:channels 19 –32

40 Mhz:channels 57 –91

41 Mhz:channels 407 –420

The use of 2,4 Ghz is allowed in all classes.

In the invitation to the event, the Organizer must announce which frequencies are to be used for what classes. For Eco Team all frequencies are allowed. At registration each driver of a team has to register 4 frequencies.

If a participant does participate in several different classes, and these are held at the same time at different race platforms, the participant has the right to ask the Platform Judge to alter his start time or start order ( for classes F1 and F3).



E. Procedure for racing


Roll call for competitors


The time for competitors to show up at the race platform is 2 minutes. The platform Judge is to call out for the competitor 3 times by name within this time to present himself at the race platform. When a competitor is called out for, the next one in line is to be summoned to start preparing his boat.

Should a competitor not be present with his boat, when his time is due, he loses the right to start in that run.

Should a competitor not be there, the preparation time for the next competitor in line is then 3 minutes. (class F1 and F3). In heat racing the heat will start without the missing competitor.

Changes in time tables can occur during an event. All competitors are themselves responsible for keeping track of any changes in the schedule, whether they are announced by word of mouth or in printing. Major changes in the time table are to be announced by

the Main Judge. When major changes do occur, ample time for charging batteries is to be foreseen. All competitors must have their boats ready for use 15 min before their time is due.


Time for preparation

All boats are to be presented at the race platform ready foruse (meaning taped up, or with

all possibleparts, nuts and bolts in place). Time for weighing, voltage check or time to

fuel up are not included in the set time window of the competitor. (also observe the part

of switches under lids in the Safety Rules)


At CC or WC the organizer has to foresee a sheltered preparation area. After being summoned the battery voltage is checked, batteries weighed, and when stated in the

Rules boats weighed as well. All this is to be done by properly trained people. After this

the boats can be taped up. Next the Pontoon Judge will asign the position on the platform

the participant must stand. After the race, the same area is to be used for further checks

like battery voltage and weight according to the specific class rules.




Announcing the start of a trial


To avoid any misunderstanding, the competitor has to announce clearly to the referee's

 on the platform he is about to start his trial by a clear signal (raising an arm, calling out or other ways). This signal can also be given by the competitor’s helper. (F1/F3). In heat racing the competitor is asked by the Pontoon Judge if he is ready. Should he so state, a delay is no longer possible.

In the F1/ F3 classes, the competitor has to allow the timekeepers to read and declare the realized time before making another attempt.



Cancelling a race or trial


Cancelling a complete event can only be decided by the Main Judge or Naviga 's Representant.

Cancelling a race or trial at any race platform is to be decided by the Platform Judge.

If during a race or trial a buoy gets destroyed, the following procedure is to be followed:

F1, F3: the trial is stopped, so is the time left. The boat is to be retrieved to the race platform. During this time no repairs, recharging or refueling are allowed. After succesful replacement of the buoy the remainder time is started once more.

All Mono/Hydro, Eco classes:

If a buoy or the transponder wire gets destroyed during a race, the race is stopped and restarted after batteries have been recharged. Boats that are retrieved after the race was stopped are not to participate in the restart. Charging time has to be observed in this event.

FSRE/ All Eco-team classes:

If a buoy or the transponder wire gets destroyed during a race, the race is stopped by the Platform Judge by means of a whistle signal. All boats are to return to the race platform.

Scored laps as well as time remaining are to be held. Repairs or recharging are not allowed at this point. After the succesfull repair of the racecourse or transponder wire the race is restarted by heading to the right hand bottom buoy .



Results and announcing results


The preliminary results of any race platform are to be made public within 2 hours. Printed lists are to be posted at a location known to all.

Not before 1 hour later then the posting of any result, this result becomes official. In that 1 hour time window an Official Protest can be made against this result. After the 1 hour time period, no Protests can be accepted.

Posting results in the evening, after races have ended is not allowed when it is not certain all competitors or Teamleaders have seen these results. The same goes for changes in the timetable.






Technical control of models


Before any race start in any class, the Platform Judge can verify the technical state of any model.

In classes with set number of cells or cell weight restriction, these are checked and verified before and after the race.

Before the race voltage is measured.

The measurement is done by means of 1 or 2 easy accessible external contacts. These measuring points have to be connected directly to the + and minusof the battery. In cases where only 1 extra measuring contact point is used, the competitor has to make sure the second measuring point (over the kill switch) does not pass through the speedcontroller.

In or at this extra contact point nothing is to be placed in between the batterie and contacts like resistance(s) diode(s) or any device that will lower voltage or influence the correctness of measurement. If at measuring it is detected some form of manipulation of voltage has been installed, an immediate disqualification is the penalty.

At World or Continental Championships or official International Naviga events the battery voltage is to be measured directly on the battery before and/or after the race.


The weight of the battery is checked before the race.

Adequate time should be provided for the competitors to properly close and tape up their boats.

After the race voltage is checked again to verify the minimal voltage has not been surpassed. If the voltage is too high (before the race) too low (after the race) the weight of the battery not according to class Rules, the participant is disqualified for that heat.

All these procedures are mandatory, should any competitior leave the race area without having everything checked, he is disqualified for that heat. For weighing and measuring voltage, the equipment used by the Organizers, are the official ones. Before the event, trials on weighing and voltage can be done to test. For that purpose the equipment will be available at Registration.

At World Championships as well as new records to be validated, the 3 best placed models are to be checked for conformity to the rules and regulations. The following items are checked:

In the F1V classes: if the cylindrical capacity of the engine is within the limit of the class the boat started in.  

If noise emmission is within the Rules.

In the class F1E if the total weight of the battery does not exceed the max weight allowed.  Voltage is checked for under voltage.

In the classes Eco, Mini Eco team Eco team, the number of used cells and voltage is according to class Rules, also the undervoltage after the race.If the minimum weight is met for mini Eco and Eco boats.

In the FSR-E class the number and weight of used batteries , and the voltage checked after the race for undervoltage.

Ic motors are to be measured when cold. A Tolerance of + 1% is acceptable.

Determing the stroke of an engine is done through the glow plug fitting with a calliper. The engine is not to be opened till after that;

Determing the bore of an engine is also done with a caliper, in the area between the top of the exhaust port and top dead point; 2 measurements are to be made (90 degrees opposite to one another) from these 2 measurements, the average is calculated.

For all measurement equipment setting standards are to be deposited.

Determing the engine capacity from the measurements is done either by computer or by data sheet. (Anex D8)

Should a speed, elapsed time or number of points is obtained that is believed to be a new record, the boat involved cannot leave the race platform untill scruteneering of the model has taken place.

Each competitor is obliged to present his boat for scruteneering and to assist to it. The preliminary things need to be done before hand are his to do. Should the competitor refuse to do so, automatic disqualification is declared. Should the results of the scruteneering not meet the set standards for the class, this also leads to a disqualification.

In this case the next in line results move up 1 place and will be then also be under scruteneering.


Records can be set in the following classes: F3 / F1


In several classes weighing of boats/ batteries and voltage measurements are done. There is to be no second measuring of weight or voltage if the set values are not met. Altering the weight of boat/battery on the scales is allowed for as long as the boat/battery remains on the scales. If the boat/battery is removed from the scales the weighing is ended.

Should the weight or voltage not meet the Regulations, the boat cannot participate in this heat/trial. Class Regulations are to be observed for this.



F.  Penalties


All the following penalties are to be declared to the competitor immediately. There is no Protest to this judgement.

If the noise level of 80db/A is surpassed in the classes F1V or F3V, the boat is disqualified for that trial or not allowed to start. This lies in the discretion of the Platform Judge.

The Battery weight is not according to class Rules (overweight) Battery Voltage either too high or too low according to class Rules.

If race number shields become unreadable or missing during a race, the boat should be taken out of the water. If this is not done, the Platform Judge may disqualify the competitor after warning him first. It is allowed for the competitor to replace the number shield by another one.

If a boat gets stuck in a buoy and the driver tries to escape from the buoy by using his motor, hereby removing the buoy from its fixed position, he is not allowed to take the restart.

If a competitor uses a frequency not assigned to him, he cannot start in that heat. Should this happen again, or should he use a non authorized frequency afterwards he will be expelled from the meeting.

If any competitor runs over a non moving boat, a yellow card with a 1 lap deduction penalty is given to the driver of that boat who hit the non moving boat, when avoiding it was possible. If the same driver hits this non moving boat a second time, a red card is

given. This means disqualification for that heat. If the non moving boat is declared a '' dead boat” by the Platform Judge any running into it automatically leads to a red card.

Should a boat pop out of the water or suddenly spin out so a collision is unavoidable, no penalty will be called.

If a competitor leaves the race platform during a race, his radio control must stay in place.

If the radio is also off the platform, this leads to disqualification for that heat.

If in certain classes, a buoy is passed on the wrong side, one is allowed to turn back and round the buoy in the correct manner. However if any other competitor is hindered or touched in doing so, a 1 lap penalty is given. Another similar incident leads to disqualification for that heat.

A slower boat can be passed on either side. The slower boat should then hold it’s course and in no way hinder the overtaking boat. Any obstruction will lead to a 1 lap penalty. If a slower boat repeats this, he will be disqualified for that heat. Any form of “Team” racing, hindering other competitors boats or even damaging them; will be sanctioned with a Red card. A faster boat overtaking a slower boat can also not cause any obstruction to the slower boat, if a collision occurs caused by the faster boat, a Yellow card will be given.

Should this lead to the early retirement of the slower boat, a Red card will be given. An obvious purposely missing of the top  buoy or any other buoy in the Eco classes, in order to obstruct or hinder another boat which is rounding the buoys in regular fashion will lead to an immediate disqualification for that heat and if repeated to a disqualification and expulsion from the event.

Unsportsmanlike conduct, hindering another competitor, causing danger to spectators or hitting the race platform, causing damage to the lapcounting equipment (transponder isle or wires) can be sanctioned by the Platform Judge at his own judgment,

a) First offense, official warning (yellow card)

b) At a second time or in case of reckless behaviour, a red card will be given (disqualification). The competitor is to take his boat out of the water immediately.


Fair play is to be respected at all times. Should a competitor behave un-sportsmanlike towards other competitors or Judges, he will be disqualified immediately from the event by the Main Judge; (on advice from the Platform Judge). Any physical violence towards other people leads to an immediate expelling from the grounds. This also counts for start helpers. Further penalty will be decided afterwards by the Naviga Praesidium.

Yellow card: 1 lap deduction

Red card : Disqualification for the heat







G. Class Regulations


Regulations for the class Eco /MiniEco




Freely built model racing boats with electric underwater propeller propulsion (Hydro/Mono drive units and surface propeller propulsion that extend beyond the length of the Hull are not permitted) with a minimum weight of 1 kg., Mini Eco minimum weight 450 gr and maximum hull length 430 mm.

Extra items such as pieces of styrofoam or balloons etc. are not allowed if they are not a permanent fixed part of the boat (in example cockpit or flood chamber).


Special construction specifications, regulations and checks in the class FSR-ECO .

The size and art of the starting number plate can be found in the general rules and is valid for all classes.

Competition objective


On one of the in appendix C1 suitable triangular course and to achieve the highest

possible number of laps in the given time is to be driven. A minimum of 3 and a

maximum of 6 models take part in each heat. Due to the lack of time the number of

models per heat can be raised, after approval from the landing stage leader/referee and  the

section leader (or main referee) to 7. However, this should not be the norm.



Special construction specifications, regulations and checks in the class FSR-ECO


The size and art of the starting number plate can be found in the general rules and is valid

for all classes


Only one set of batteries may be used per heat, batteries are defined per Annex 1.

The accumulator/propulsion pack must be easy accessible in case it needs to be checked. If a separate accumulator is used for the receiver then a noticeable switch is to be used to break the circuit.

The used electric motor has no restrictions.

The Drive unit must be able to be switched on and off by the radio control unit, or be fitted with a speed controller.

The model is to be weighed off the water in a ready for launch condition. The total weight including the receiver and Drive unit accumulators plus their respective cables, connections and mounts, may not be less than 1000 gms in the classes FSR ECO.

Not less than 450 gms and maximal length of 430mm for Mini Eco (incl. starting number plate).


For battery weight and battery voltage see class rules.


Competition rules


The competition is carried out on a triangular course corresponding to the NAVIGA rules, with the exception of the turn. The race direction is anti clockwise. The start line runs in a straight line to the uppermost buoy. Once the models are in the water, the race begins with an acoustic signal sounded by the landing stage leader. At this time the boat must lie with its stern to the landing stage.

If the racenumber is at the back of the boat, this becomes the stern of the boat and has to touch the landing stage.

If a model has a late start and the first of the models that started on time has reached the bottom left, then the late starter must start towards the bottom right buoy. In no way should he then hinder the oncoming models.

There are 3 or 4 heats in a Race. The results of the 2 best heats are added. The 6 competitors with the best results advance to a final heat were the final result is determined. (Otherwise, for evaluation see regulation for competitors D No. 4)



 see annex A1


During a race, boats that have broken down can be picked up by the recovery boat at the end of the heat, apart from when a boat sinks or might sink.

If a buoy is passed on the wrong side, the competitor has the right to turn his model and drive around the buoy on the right side, provided that he thereby does not hinder the other competitors. If this does not happen, the round is not counted.

Also after a heat / race the model must correspond to the construction specifications of his class. The landing stage leader/referee can check this at any time, also after a heat / race.



Regulations for the Eco-Team class and Mini Eco Team



Eco Team is a team event for boats of the Eco class,


Race Rules

At least 2 and at most 3 competitors make up an Eco team or Mini Eco team, using maximum 3 boats. For all boats used, the same built requirements are valid as in the Eco or Mini Eco class. This goes as well for allowed batteries, number of cells used as for general rules for racing. The following changes towards the Eco Rules are to be noticed.

Only 1 boat per team can be in the water. Dead boats are recovered during the race, the next boat of a team cannot start untill the dead boat is in the recovery boat. For duration of a race see annex A1. Only 3 sets of batteries per team are allowed. Charging batteries during a race is not allowed. Every team member can only bring 1 boat to the platform, and can also drive only his own boat. Swapping batteries within the team is allowed.

The start is given as in the Eco class. All further boats starting from the platform head to the right bottom buoy. Hitting the rescue boat leads to a general disqualification of the whole team. Mixed teams (participants from different countries) are not allowed at

European or World Championships.  Maximum 6 teams form a series. At registration all participants from the team should provide 4 frequencies. In the Eco Team Junior class 1 senior person is allowed per team to give aid and advice. This senior person can however not act as start helper. He can only interfere in the cause of events after the ok from the Platform Judge, when the team is in danger. There is no protest possible towards the Platform Judges decision.



Regulations for the FSRE class



In the FSR E class only single hulled boats with submerged drive and electric motors are allowed. Different types of hulls or drive systems are not allowed. So called Mono or Hydro boats or similar are notallowed.

Using 2 motors or up to 2 propshafts by using a gearbox for example are allowed.

Runtime is 15 minutes. The course to be used is the M course as described in Annex C5. It is made up from a modified Mono/Hydro Oval. A heat consists of maximum 8 boats.

The start is towards the middle buoy ( to be passed on the righthand side, next towards the left hand top buoy) after the signal is given.

If a transponder system with an “island” is used, this island is to be passed on the right hand side.

All boats should be in the water with their stern against the platform before the start is given, held in place by the start helper. On the bottom straight (parallel to the raceplatform) there are 2 buoys (example, the 2 Eco triangle s). These buoys cannot be passed on the inside (cutting into the inner part of the M coarse). Going into the inner part of the M course a first time leads to a yellow card, a second time will lead to a red card.

Only self righting boats are to be used. Boats stopped dead in the water will be recovered by the rescue boat. Only batteries as stated in Annex A1 are to be used.

Splitting up the total number of batteries into separate battery packs is only allowed when using NiMh or LiFePo batteries. Charging batteries during a race is not allowed.

Changing of batteries is only allowed with NiMh batteries, making sure the total cellcount or possibly the cellweight is not exceeded.

There is no minimum or maximum weight for boats used.

When a buoy is missed, it is allowed to turn back to round the buoy correctly,however without hindering any other competitor. If no attempt is made to turn back and round the buoy correctly, that lap is not counted.

The top 6 qualifiers will then race for their final result in a Final heat. (If this is not the case see guidelines for participants D nr. 4) In all 3 or 4 heats are run. the 2 best results are then added to make the final result.



Regulations for the Mono, Mini Mono/ Hydro and Mini Hydro classes


Boat requirements


Boats to be used in the Mono, Mini Mono/Hydro; Mini Hydro classes are boats that resemble real boats. This semi scale appearance can be achieved by including things such as driver, canopies, engines or exhaust pipes. In case of a kit boat by using the parts provided by the manufacturer such as lids and covers. Pure performance models are not allowed. Extra items to make a boat to self-right such as pieces of foam or balloons are not permitted as long as they are not fixed part of the boat (canopy or flood chamber for example).

Mini Mono or Mini Hydro boats have a length restriction of 450 mm  and a minimum weight of 450 gr. The length is the hull length (sponsons included in the case of Mini Hydro) measured from the transom to the nose, rudders and number plate not included

All boats must be propelled by 1 or more semi-submerged propellers and 1 or more motors. There is no restriction on motor(s) used.

All boats must have a racenumber that is clearly readable from both sides. The requirements for the race number are described in the general rules. A second is allowed if in doing so, the visibility from both sides is guaranteed.


Batteries and battery weight

,see Annex A1M



There are the following classes:

Mini Mono: single hull boats (observe length , weight and battery rules)

Mono 1: single hull boats

Mono 2: single hull boats

Mini Hydro multi hull boats (3 point boats, catamarans, observe length, weight and battery rules)

Hydro 1: multi hull boats (3 point boats, catamarans)

Hydro 2: multi hull boats (3 point boats, catamarans)



see Annex A1


Rules for racing

Before the start boats in the Mini Mono or Mini Hydro class are to be weighed and measured.


Race course and number of participants

Boats go round a coarse, made up by 6 buoys, clockwise. Measurements for the course are to be found in the adjoining drawing (Annex C4). The distance from the bottom base line to the platform is 15 m. The distance from the left lower buoy or right lower buoy to the banking, is to be minimum 15 m. On the start/ finish line an extra buoy must be placed, slightly inside the race coarse. Start and finish line must be 5 m left to starting place number 1.

Competitors are to be divided into groups of max 6 people; if possible all groups should be made up with equal numbers.

In the coarse of the event, under manned groups are to be filled up.

3-4 heats per group are to be run. The 2 best results are added up. The 6 competitors with the best result make up a Final to the decide the overall winner. More info in Rules for Racing D nr 4.


The start procedure


After the command “boats in the water“ is given an accoustic signal will sound.   At

this point all boats must drive up to the 3 righthand side buoys, staying well outside of them, (according to drawing seen in annex C4) up to the startline placed 5 metres from

the lefthand side of the Platform. If any boat hasn't crossed the bottom baseline within

5 seconds from rhe signal, a late start is not allowed then. Slowing down

or stopping completely is also not permitted. The start is declared by race control as follows:

10,5,4,3,2,1 start. Only after this command the actual racetime starts. An early start

(crossing the startline before the command start is given, slowing down or stopping all

together) will be punished with a 1 lap deduction. The Platform Judge must declare an early start to the competitor after completion of the first lap.


Fairness is the most important rule


Overtaking can be done on any part of the course. Boats driving on the “ideal line“

can only be passed on the outside. The ideal line is defined as the fastest line between

any 2 points or buoys that make up the race coarse.


If a boat goes outside the ideal line, it can be passed on the inside.This also applies in both turns.

In overtaking, no competitor can hinder another boat by changing lanes or cutting across

the ideal line towards a buoy.


Dead boats are to be passed at great distance. If a dead boat is hit by any competitor, the

Platform Judge will pass penalty according to the part „Rules for Racing


If a buoy is passed on the inside, a 5 second penalty is given to that competitor. If a second buoy is missed 1 lap will be deducted from the final score. Any further missed buoys will be penalized by another lap deducted for each missed.  Turning around trying to avoid missing a buoy is not allowed. Boats stopped dead in the water will be recovered only after the race has ended. Only in cases where the boat is sinking, or looks like it will sink, the Platform Judge will summon an immediate recovery. It is adviced to the Organizer of the event to have the Platform about 1m to 1,2m higher up and away from the water.

Even after the race, all boats must meet the class regulations. The Platform Judge can check on these even after the race has finished.


Race order in the seperate classes are to be run as follows:

Mini Mono, Mono1-2 then Mini Hydro,Hydro 1-2

Juniors will always run first.


Regulations for the classes F1V and F1E


F1V class

 In the F1V class radio controlled boats with ic motors are used. There are the following sub classes in the F1V Class:

1. F1-V3,5: Freely built boat models with ic motor of max 3,5 cc, submerged propeller driven, driving a speed coarse as described in Annex C2

2. F1-V 15: Freely built boat models with ic motor of over 3,6 cc and max 15 cc, submerged propeller driven, driving a speed coarse as described in Annex C2

In all classes 1 or more motors can be used. The total engine capacity cannot exceed the maximum engine capacity allowed for the class. The Main Judge has at all times the right to have the total engine capacity checked.


F1E class

In the F1E class freely built boats with electric motors are to be used using a submerged drive. There is no weight limit (neither minimum nor maximum weight) and the battery voltage is limited to max 43V. The maximum weight in Lipo is 1400 gr. The goal is to drive around the Naviga triangle in 2 directions, according to annex C2

Number of cells, weight, type of batteries and voltage are to be as in Annex A1.

Prior to the start the voltage is checked, this voltage should be not higher as set in Annex A1. This measurement is done over the kill switch. The wiring and accessibility of batteries in the boat should be such that a clear check of the used batteries is possible.


General rules for starting and ending a run

During his run the competitor and his helper have to stay within a designated area.

The competitor as well as his helper can move around freely in this area. Only 1 helper is allowed per competitor.

A radio check is done before the start of each run. The Platform Judge will check to see if the assigned frequency is used by the competitor. Should this not be the case, the Platform Judge may refuse the competitor from making his run.

Recovery of dead boat within the set time frame is allowed.

After finishing a run, the competitor is to take out his boat from the water immediatelly and his radio to be switched off.

If a model gets out of control during a run, 1 minute is allowed to restart, if not the run will be considered as completed. If the competitor or his boat be hindered in any way (example radio interference caused by another competitor) he can claim a rerun after the end of his run. Only 1 rerun can be claimed.

When a competitor is forced to end his run due to these circumstances, and the Platform Judge allows a rerun, then the whole run is redone. Any times achieved in the missed run are then not valid.


Race procedure

Racing in the F1V and F1E classes are done in 3 runs, which are to be held over separate days at European and World Championships. A 5 minute preparation time is given to each competitor before his actual run.

Within the 5 minutes each competitor has, starting as he steps on the platform, he can make as many attempts as he wishes. After the end of a run the Platform Judge will summon the next competitor to the platform as soon as possible. The competitor or his helper have to clearly show the start of the run by raising hand. Within his runtime, repairs to the boat are allowed with the exeption of motor changes or recharging or changing batteries. In the F1V class, refuelling is allowed only from a fuel bottle that was on the platform at the moment the run started. The time does not stop for refueling. Racetime starts at the signal given by the Platform Judge. Changes or repairs to a boat during a run cannot be such that  the boat does not meet the class specifications.

Recovery of a dead boat during a run is allowed, the race time is not stopped during recovery.

Once a boat crosses the start line, the run is valid.

Every boat has to run the coarse twice in opposite directions. The start and finish line are the line from the top to the turn buoy and the paltform.

The start of a run will be from left to right. Touching buoys is not considered a fault.

All buoys have to be passed by the outside. Going inside the line between 2 buoys is not considered a fault as long as no corner buoy is missed in such.

If a buoy is missed, the competitor has the right to turn back and round the buoy in the correct way, even if he crossed both lines between the buoys.He can then continue his run.

If any buoy is not passed in the correct way, the trial is not valid.


Validating a run

The result will be measured by the time keepers in seconds and 1/100 th of seconds. The best of all trials will be the official result.

In the event of equal times, the next best result of the competitor will decide on classification. Should after 2 joined results there still be an equal result between 2 competitors, the 3rd time will then decide the classification. Should 2 competitors still be equal after that, the competitor with the lower sound emmision (F1V) will be

declared winner, in F1E the further results will decide on classification.


Announcing results

After all series the result are to be put out containing the following:

- type or race

- class

- classification

- Name, surname and Nationality of the competitor

- results of noise emmision measurement

- runs made including time accomplished

- best run made

- Name, Nationality and Referee number of the Judges

- Signature of the Main Judge and Platform Judge



Regulations for the class F3V and F3E


Freely built boats equiped with electric or internal combustion motors are to be used for the F3E and F3V class. In F3E/V only a boat propeller is to be used.

The race course is triangular, made up by 8 gates. (side length 30m see Annex C3). The course is to be driven in a set order. Points are awarded according to the time elapsed.




Race procedure

Racing in F3V and F3E is done in 3 seperate heats, and for Worlds or European Championships, spread over 3 days. Each competitor has, included the time to prepare, a 5 minute time window to do his trial.

In these 5 minutes, starting by stepping onto the race platform, as many attempts as wanted can be made. The Platform Judge will declare the course open after each trial as soon as possible, however allowing the timekeepers to reset their stopwatches.

The competitor or his helper must clearly state the start of their run. During the racetime repairs or modifications to the boat are allowed. Changing motor, refueling, changing or recharging of batteries however is not allowed. Retrieving of dead boat is allowed during a run.

If a boat has crossed the start line at the end of his trial, the run is valid and counted for.

Racing is done on a triangular course as shown in Annex C4. The maximum time per trial is set at 150 seconds. Timing of a trial starts as the 1st gate is passed with the bow of the boat, and ends as the last gate is passed with the bow.

All 8 gates on the figure course are to be passed twice, in the correct order and in the shortest time possible. Extra points are given for a faultless run, points are deducted for buoys touched according to the list (as seen in Annex D4).

Each gate is only to be attempted once.

A gate is considered passed when the boat has passed the baseline between the 2 buoys making up that gate.

A buoy is considered touched, when it visibly moves, if both buoys of a gate are touched, this is considered as 1 fault.

A gate is considered missed, when the boat crosses the base line on which both buoys making up that gate, is passed outside the 2 buoys.In this case maximum points for that gate are deducted.

All gates not passed in the correct order are considered as missed

For batteries in the F3E, weight, number of cells, see Annex A1.

Validating a run in F3V or F3E

The result of a run is made up in points according to the list (Annex D5) by comparing the time in seconds and 1/100 th of seconds to the list.

The best of all trials is taken as final result. In case of equal points, the next best result of all trials is then taken. Should there still be a draw the next best result(s) will be counted till there is no more equality in points.

From the set maximum time of 150 seconds 2/100th of a point is subtracted per each full 1/100thof a second. 5 seconds make 1 point thus.


After the series a List with results is shown, this list provides the following data:
