My dear friends,<\/strong><\/span><\/p>\n

In this post I have collected all the proposals you have sent. Some of them are contradicting to each other, so read carefully, discuss with your teammates and try to come to the TC with clear ansver of yes, or no. At the committee meeting we will rather vote. There will be no time to discuss such amount of proposals on site.  <\/p>\n

One remark in advance from my side: The freeing up the connectors I would allow with the following restrictions:
\n– The connectors must make the reverse conneting impossible. Neither by means of polarity, nor by current flow. I.e. ESC and Battery side can not be overchanged.
\n– The connectors must be set the way, the limiter measures the highest voltage only of the battery pack. I.e. measuring with pin inserted into the ballancer port is not allowed.<\/p>\n

Looking forward to see you at the Worlds!<\/p>\n

Dear friends<\/p>\n

Belgian proposal<\/strong><\/p>\n

1.      Start procedure oval :<\/p>\n

The start procedure was changed from 10 sec to 6 sec as a main reason to have less accidents at the start line.
\nNow everybody starts full throttle and on an official parcours is not able to reach the starting line within the 6 sec.
\nThe result is that at the first boy, there are more crashes than before.
\nSo our proposition is to change back to the 10 sec rule.
\nIf the rules are followed and enforced when necessary, this is the best solution in our opinion.<\/p>\n

2.     <\/p>\n

We propose to use the same start procedure for mini fsre as for fsre.<\/div>\n

Hello, I send you the proposals from Bulgaria.<\/strong><\/p>\n

Proposal 1: Free the connectors rule for big limiters like in mini classes. Every competitor use connectors by their own but must provide adapter to 5.5mm and 6.0mm like in the existing rule. Reason: The 5.5 and 6.0 connectors are week, they need to be exchanged every season. Most of 6.0mm are week and get loose in just a few races, there are planty of options for more reliable connectors. Proposal 2: Free the type of Litium batteries used, LiPo, LiFePo, LiIo, LiHV, but keep the rule for minimum weight and energy limit. Proposal3: Raise the Voltage Limit in all M-classes to 43V<\/p>\n

Thank you, Best regards,
\nTodor Stoyanov<\/p>\n

Polish proposals for changes to the NAVIGA Section M Rules 2026<\/strong><\/p>\n

1.
\nWe propose that batteries be weighed before racing during technical inspection, and then
\nmarked with a seal\/sticker that must remain visible on the battery installed in the model
\nwithout removing it.
\nBattery weighing today is fundamentally different from the old \u201cweight battery\u201d regulations
\n\u2014 the battery must meet a minimum weight, not a maximum one. Therefore, there is no
\nrisk of increasing the battery weight after a race, for example due to water entering the
\nmodel.
\nRemoving batteries before every heat often creates difficult situations, including dangerous
\nones such as short circuits, which could be avoided with this solution.
\nAt the request of the judge, an additional battery weighing may be carried out after a race,
\nand it shall be mandatory for the top 3 competitors in the final.<\/p>\n

2.
\nWe request that, in the event of a model failure on the water, only the hull be considered the
\nmodel carrying the license number and racing number, similarly to the rules concerning the
\nplacement of model registration (license number), which cannot be placed on a float or
\nhatch cover.<\/p>\n

This concerns hydro classes in particular.<\/p>\n

The purpose is to establish that the model consists of one part, not three or more. If floats or
\nother parts separate from the hull during a race, under the current rules another competitor
\nmay not touch any part of the damaged model, even if it is broken into three or more pieces
\nand these pieces are located in different areas of the course.
\nThis creates many situations in which other competitors are disadvantaged because they
\nare forced to avoid multiple parts of a damaged model, and this may lead to unfair
\ndisqualification of a competitor.<\/p>\n

3.
\nWe propose removing limits on the number of battery cells in all classes.
\nWe believe that the use of limiters and a specified energy limit is already a sufficient factor
\ndistinguishing the different classes.
\nSpecifying the number of cells is a relic from the times when energy was limited by battery
\nweight.
\nThe only limitation should be a maximum voltage of 43V.<\/p>\n

4.
\nWe propose removing from the regulations the possibility of using NiMH and LiFePO
\nbatteries.
\nFor several years nobody has been using these battery types, so this rule has become
\nobsolete.<\/p>\n

5.
\nWe propose that, in parallel with the points system, results in F3 classes also be shown in
\nseconds.
\nFor each penalty point, 5 seconds are added to the result.
\nExample:
\nIf a competitor completes the course in 20 seconds with no penalty points, the result would
\nbe: 146.000 points \/ 20s
\nIf a competitor completes the course in 20 seconds and receives 2 penalty points, the result
\nwould be: 144.000 points \/ 30s
\nThe purpose of introducing parallel time scoring is to make F3 results easier to understand,
\nas the current scoring system is unclear to many competitors and reduces interest in this
\nexcellent class.<\/p>\n

6.
\nWe propose changing the buoy regulations for Eco classes.
\nCurrently, the buoys for Eco classes are regulated together with the buoys for F1 and F3
\nclasses (the regulations require them to protrude 10 cm to 20 cm above the water surface).
\nA buoy protruding only 10 cm in an Eco race does not fulfill its purpose. In addition, such a
\nsmall buoy can easily be damaged, which may lead to a race being repeated.
\nWe propose separating the Eco buoy regulations from the F1 and F3 regulations, and
\nchanging the protrusion height of Eco buoys to 20 cm to 30 cm above the water surface.<\/p>\n

7.
\nWe propose introducing the possibility of measuring times in F1 and F3 classes using a
\ndedicated timing device connected to the results presentation system, instead of using the
\ncurrent three-stopwatch timing system, provided that it is not an AMB\/MyLaps device.
\nSuch a device would require approval from the NAVIGA Section M Committee, led by the
\nSection M Leader.<\/p>\n

Proposal of Hungary<\/strong><\/p>\n

Canceling of sound measuring at IC classes<\/p>\n

The sound measuring at IC classes are out of date. The class is shrinking because the sound limits are almost undoable. The sound effect of F1E classes are much more higher because of the frequency of the noise. For the organizers its complicated to build the proper measure station because of the terrain at the lakeside, so the measuring of the noise is not validable. Many variant  physical relations effects on measuring ( humidity of the air, plantation at the lake, the material of the lakeside) . The measuring procedure and result cannot be repeatable many times, which is the base of a correct rule.<\/div>\n

Proposal of Italy<\/strong><\/p>\n

Dear Chef of the Commission Section M,<\/p>\n

I am following up on the emails previously exchanged between FIM and Naviga, and I would like to bring the following proposals to your attention:<\/p>\n

    \n
  1. Rewriting and Revising the Regulation<\/strong>: It is essential to make the text more modern and clear, especially to facilitate understanding for new individuals, not just for those who currently follow it out of inertia. The current regulation is outdated and scattered. I have already shared a draft with you that we can work on.<\/li>\n
  2. Integration on the Use of Batteries and Limiters<\/strong>: I propose the inclusion of specific guidelines regarding the use of batteries and limiters for the various categories, in order to improve the management of international and national races.<\/li>\n
  3. Regulation of the Issuance of Clearance<\/strong>: I suggest revising the procedures for issuing clearance for pilots requesting to participate with another nation. In addition to the general conditions already present in the regulation, limited and well-motivated cases should be included to facilitate this operation, avoiding approximate evaluations.<\/li>\n<\/ol>\n

    I remain available for any further clarifications and insights. We are in discussion with the one organizer here in Italy for try to organization the WC 2027.<\/p>\n

    Best regards,<\/p>\n

    Alessandro Cremona<\/p>\n

    German Naviga Section M Rule Proposals 2026<\/strong><\/p>\n

    German Naviga Section M Rule Proposals 2026<\/p>\n

    1. Energy: Reduce the limits as follows (each item to be voted on separately)
    \n1.A)
    \nMini Eco                20 Wh
    \nMini Eco Team   3x 20 Wh
    \nMini Mono             20 Wh
    \nMini Hydro            20 Wh
    \nMini FSRE             40 Wh
    \n1.B)
    \nEco                      55 Wh
    \nEco Team         3x 55 Wh
    \nMono 1                55 Wh
    \nHydro 1                55 Wh
    \nFSRE                  165 Wh
    \n1.C)
    \nMono 2               110 Wh
    \nHydro 2               110 Wh
    \nReasoning: the high amount of available energy has made boats too fast and therefore dangerous,<\/span>
    \nespecially in Mono 2 and Hydro 2. We suggest this moderate reduction of energy limits so current boats can<\/span>
    \nshall be used. Battery weights remain the same \u2013 meaning the batteries are less stressed and have a longer<\/span>
    \nlife>me. Each item to be voted separately, so at least Mono2 and Hydro 2 can be reduced in Energy for<\/span>
    \nsafety reasons.<\/span><\/p>\n

    2. Connector system free of choice or MP-Jet 3,5mm<\/p>\n

    2.A) Any connector system allowed in all classes (as already permitted in Mini): Each competitor may use
    \ntheir own connector system between battery, limiter and ESC. For measurement purposes, adapters to the
    \ncurrently required connector system must be provided.
    \nReasoning: The currently prescribed connectors are heavy, take up a lot of space, and usually become<\/span>
    \nloose\/unreliable after repeated plugging cycles. In addition, different suppliers have varying dimensions,<\/span>
    \nmeaning the connectors are not always compatible although they are marketed as 5,5 or 6,0mm.<\/span>
    \nSimilar to batteries, motors, props, etc., we would like to allow free connector choice and make the<\/span>
    \ncompetitor self-responsible to assure correct connection of battery, limiter and ESC.<\/span><\/p>\n

    2.B): if 2.A) is rejected, we propose: 3.5 mm MP Jet connectors on the battery side instead of the currently
    \nrequired 5.5 mm connectors.
    \nReasoning: These connectors fit very securely even after more than 100<\/span>
    \nplug\/unplug cycles, have lower weight and volume, and a very low internal resistance. Successfully used in<\/span>
    \nracing for over 20 years. The longer durability compensates for an allegedly higher purchase price. See:<\/span>
    \n    https:\/\/mpjet.com\/shop\/gb\/928-mp-jet-connectors<\/a><\/span><\/p>\n

    3. Race start (applies to all Mono and Hydro classes; each a separate proposal)<\/p>\n

    3.A) Individual start in driving direction: The boats start individually one after another, following the call of
    \nthe respective starting number, in driving direction (= to the left), with an interval of 1 second. The left boat starts first, the right boat last. Runtime must be measured accordingly with a one-second offset for each
    \ncompetitor. Reasoning: This system has been in use for 20 years and prevents crashes at the start. It is less
    \nstressful and safer for boats as well as drivers, judges and rescue boat crews.
    \n3.B) If proposal 3.A) is rejected, we propose: return to the 10-second starting time instead of 6 seconds. If
    \nproposal 3.A) is accepted, this proposal [3.B)] becomes obsolete.
    \nReasoning: Especially Hydro races have
    \nshown that with 6 seconds, there are just as many crashes.
    \n3.C) If proposal 3.A) is rejected, we propose: no yellow card for braking \/ reducing speed during the start
    \nprocedure, i.e. within the 6 or 10 seconds. If proposal 3.A) is accepted, this proposal [3.C)] becomes
    \nobsolete.
    \nReasoning: It is very difficult for the judge to simultaneously observe 6 boats and reliably<\/span>
    \ndetermine whether there was actually a reduction in speed.<\/span><\/p>\n

    4. Hull length<\/p>\n

    4.A) Completely abolish the maximum hull length in all Mini classes. Reasoning: The available energy
    \nnaturally regulates the size, just as in the other classes. This would help make the small boats more
    \nmanageable in stronger wind and waves through the potentially increased size.
    \n4.B) If proposal 4.A) is rejected, we propose: In Mini Mono and Mini Hydro, limit the total length to 53 cm
    \nincluding all attachments (i.e. strut, propeller, number plate, rudder maximum 8 cm). An exception applies
    \nto a rudder folded upwards during the race \u2013 this does not count. Hull length itself remains limited to 45
    \ncm.
    \nReasoning: clarification and prevention of work-arounds that make the boat artificially longer with very<\/span>
    \nlong shafts.<\/span><\/p>\n

    5. Ban unnecessarily protruding tubes on Hydro boats: maximum 4 cm beyond the outer sides of the
    \nsponsons. This applies only before the start \/ at the beginning of the race (a protruding tube after e.g. a
    \ncrash is irrelevant).
    \nReasoning: There have been cases where the sponson tube extended approximately 10<\/span>
    \ncm beyond the outside of the sponson (not because of an accident during the race). Besides acting as an<\/span>
    \naerodynamic brake, this unnecessary extension serves no purpose other than making overtaking more<\/span>
    \ndifficult or even provoking crashes or damage to other boats.<\/span><\/p>\n

    6. In the Hydro classes, the hull and the sponsons of the outriggers should each be painted at least one third in a bright, highly visible color.
    \nReasoning: Oftentimes the middle hull is painted appropriately, but for<\/span>
    \nexample black carbon sponsons are not painted at all.<\/span><\/p>\n

    7. Check-in and Check-out Procedure:<\/p>\n

    7.A) Measure the length and total weight of the boat including the battery before the race. Reasoning:
    \nlength and weight could possibly not be correctly determined after the race due to crashes or water in the
    \nboat.
    \n7.B) Measure battery weight after the race. Reasoning: this saves time and stress during check-in because
    \ncompetitors no longer need to install the batteries into the boats in the checkin area.
    \n7.C) In finals for the top three finishers, otherwise on a random basis or in case of suspicion: after the race,
    \nboats must be opened under supervision to inspect the limiters, including all limiter connections and
    \nprogramming.
    \nReasoning: The idea is to clarify the possibility and necessity of checking limiters especially in finals in order<\/span>
    \nto prevent fraud.
    \n<\/span>
    \n8. Questions (no proposals)
    \nPlease clarify based on the existing rules: During which exact period do the 2 minutes apply? Is it allowed to
    \ncheck in with a B-boat? Is it allowed to check in with 2 boats and then decide on one boat during
    \ntransponder check? If something was overlooked during registration, for example the battery voltage was
    \nnot recorded \u2013 who is responsible?<\/p>\n

    Proposal of Czech Republic<\/strong><\/p>\n

    Good morning Csaba,<\/p>\n

    1. On the triangel change the diameter of the bouys to 20 cm, the same bouys as on the oval. The existing bouys (diameter 10cm) in some case make it impossible to clearly determine whether the model has rounded the bouy on the correcte side.<\/div>\n
    2. FSRe changes the race time to 10 minutes and 2x3S batteries like the Mono2 and Hydro2<\/div>\n
    3. In case of equal results in the final heat, the results from the qualifiying will be used to determine the order<\/div>\n

    Thai Proposal<\/strong><\/div>\n
     <\/div>\n
    Dear National Section Leaders, my dear friends,
    \nDuring last seasons when we ran FSR-E classes we found two different start procedures. Yes, it is right:
    \nFSR-E belongs to M-section with a start procedure to start to the middle buoy.
    \nMini FSR-E belonged to E section first and was taken over from M-section later. For this reason, the start
    \nprocedure is to the downside, right buoy.
    \nTwo different procedures for similar classes make no sense. So here is the first proposal:
    \n– Equalize the start procedure for both classes to start to the downside, right buoy. The first lap
    \ncounts.
    \nThailand has a second proposal about start procedures for FSR-E and Mini FSR-E. As FSR racing is taking
    \nplace sometimes on lakes with a high pier wall it is difficult to place the boats in water before start. (and
    \nthere is something more) In our opinion throwing the boats into the water after start signal is a better
    \nsolution, and here is proposal two:
    \n– After radio check the boats remain on the stand fully armed. Nobody is allowed to touch the
    \nboat any more and keep a 1 meter distance. After the start signal the boat will be thrown in the
    \nwater and steer to the downside right buoy. (Proposal 1). Reason is (beside the high pier walls)
    \nto avoid jams or bottlenecks on the first buoy.
    \nI hope this letter will be understand as a base for fruitful discussions as it is meant to be.<\/div>\n
     <\/div>\n
    Thanks and best luck for the upcoming races. See you soon<\/div>\n

    Proposal of Ukraine<\/strong><\/p>\n<\/div>\n

    Mini fsr-E was first demonstrated and held as a demo class in Slovakia in 2023 and aroused considerable interest among athletes of section M. Due to the division of the world championship into ovals and triangles, the number of classes has decreased and the number of participants in each individual class has increased significantly. A new class of mini models, based on 2 mini class batteries of 21W each, giving a total of 42W. It so happened that batteries in the form of 2s2p, 3s2p, and 4s1p are allowed, (or at least 280 grams and 42w) but the possibility of using 6s1p is not specified… Because two 3S batteries connected in series give exactly 6S. In the 6S configuration, the current drops twice, (compared to 3S), which gives greater efficiency and the ability to use smaller regulators, thinner conductors, etc.
    \nThere are many good and affordable regulators that support 6S.I propose to addet for allowing the use of batteries no larger than 6S, weighing at least 280 grams and with a power limit of 42W.It be logical, with current lipo packs for mini classes.Evgeniy Gromov

    1. Free connections on Energy Limiters in the boat, until the following conditions are met:<\/div>\n
    \n

    – The voltage MUST be measured on the battery power poles, not on the balancer port.
    \n– The limiter can not be accidentally connected with reverse polarity.
    \n– The limiter can not be connected the way, the battery and ESC side changed over.
    \n– The racer must provide adapters to make standard connections described in Annexes. <\/p>\n

    2. Free the battery cell numbers in group categories (Eco, Mono, Hydro,FSRE) up to 6 cells maximum, keeping the minimum battery weight of the Energy limit class. HV and other LiPo cells accepted. <\/p>\n
