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
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
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
As long as the diver is
busy there is to be absolutely NO driving boats anywhere on the lake.
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.
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
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
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
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
3 timekeepers in the classes F1 and F3
1 knowledgeable person to operate the lap counting
Guidelines for participants
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
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
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
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
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
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
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
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.
In all classes that are
run for a certain amount of time, the time is to be kept up to 1/100th of a
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
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
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
The following dimensions
are to be respected:
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
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
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.
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
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
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
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
F1 V: 27 Mhz: channels 1 -5
40 Mhz: channels 50, 52
41 Mhz: channels 401, 403
F1 E : 27 Mhz: channels
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
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
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
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
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
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
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
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
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
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
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
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
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.
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
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
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
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
Should a boat pop out of
the water or suddenly spin out so a collision is unavoidable, no penalty will
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.
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

and maximal length of 430mm for Mini Eco (incl. starting number plate).
For battery weight and
battery voltage see class 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
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 /
Regulations for the Eco-Team class and Mini Eco Team
Eco Team is a team event
for boats of the Eco class,
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
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
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
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
Mini Mono: single hull
boats (observe length , weight and battery rules)
Mono 1: single hull
Mono 2: single hull
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
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
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
In overtaking, no
competitor can hinder another boat by changing lanes or cutting across
the ideal line towards a
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
Regulations for the classes F1V and F1E
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.
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
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
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.
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.
After all series the
result are to be put out containing the following:
- type or race
- Name, surname and
Nationality of the competitor
- results of noise
- runs made including
- 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.
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
A gate is considered
passed when the boat has passed the baseline between the 2 buoys making up
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
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
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
