The boat must run first in it’s primary class and then if the owner wishes can race again in the next class up. ie…AA must race in own class first and then again in the A class. (This rule does not apply to other classes). An A class boat must run in its own class first, and may run again in the B class (always primary class first in the case of a 2 heat race day). Rule 11.4 still applies.
11.7 Three types of racing are to be used for championship events: 1. Chaseboat 2. Endurance 3. Sprint
11.8 During an OMRA event all participants have a personal responsibility to ensure that Health and Safety issues are observed and that where necessary any concerns are brought to the attention of the Officer Of The Day.
12. Chase Boat event
12.1 Course to be a minimum of two miles in length.
12.2 Models to be individually timed, the maximum time limit for the run to be set by the Officer Of The Day based on conditions of the day.
12.3 Re-runs will only be permitted if the chase boat breaks down or is too slow.
12.4 On-course restarts are permitted within the time limit unless otherwise directed by the Officer Of The Day at the beginning of the event.
Note: – Run finishes when model crosses the finish line or the time limit has expired, which ever comes first
12.5 Competitors, spotters and rescue crew will wear lifejackets at all times. The chase boat motor should have a ‘dead man’s handle’ fitted wherever possible.
12.6 DNF Scoring – Boats that gain a DNF after the halfway/intermediate point as set by the OOD be given a level share of Championship points from the remaining positions, after those points have been apportioned to those boats who complete the course.
Those that DNF before the halfway point will be given a level share of Championship points from the remaining positions, after points have been apportioned to those boats who complete the course and those that complete more than half the course. Points in all cases above 0.5 and above, will be rounded up to a whole number and points split below 0.5 will be rounded down to whole number points.
[Example: 3 boats in a class complete the course and 3 have DNF’s but stop after the intermediate point. They each get a level share of 4th 5th and 6th points (a total of 19 divided by 3 = 6.3) and this is rounded down to 6 points each. The remaining DNF’s before the half point (eg. 2) will each get a level share of 7th and 8th points (a total of 7 points divided by 2 = 3.5 and rounded up to 4).
13. Endurance Race Event
13.1 Course to be approximately 300 – 400 yards around 3 to 4 marker buoys or as determined by the water available and by the Officer Of The Day. This will be raced in a clockwise direction.
13.2 Race duration is to be left up to the race organizer as long as the total race time adds up to a minimum of 30 minutes or up to a maximum of 60 minutes. Race organizers are encouraged to divide the total race time into two separate heats per class when ever possible.
13.3 A designated area next to the waters edge to be set up as the pit area at all events. This is the only area in which a boat’s engine may be started for the purpose of running in a heat ie: there will be no carrying of boats with engines running outside this area.
13.4 Races may be started with a full course mill start or where the location allows, a safe dead engine start.
– A mill start allows competitors to release their models onto the water and proceed in a clockwise direction 2 minutes before the start of the race. Models will then travel the full course during this time with the aim of approaching the start line at the end of 2 minutes. Any cutting of the course during this stage will attract a 5 lap penalty.
– A dead engine start, as the name implies, requires that all engines be stopped one minute before the start of the race. Then, at the start signal, engines are started, models launched and racing begins immediately.
13.5 A standard start will be used for the races by use of blasts from an air horn. One blast for start of mill time, two blasts for the start of the race and three blasts for the end of the race. At any time, more than three blasts indicates danger and racing must stop immediately.
13.6 A model will start to score laps from the first time it crosses the start line after the start and must complete each time a full circuit of the course to register laps. Any model jumping the start will have to do another legal lap before being counted.
13.7 Models that fail to start or have stopped may join or rejoin the race when safe to do so.
13.8 There will be rescue available during the course of the race for any model that has stopped. The rescue boat will be manned by two persons over the age of 17 years who must wear lifejackets when in the boat. The wearing of hard hats is recommended but not compulsory. The rescue boat has the right of way at all times and all boats must visibly slow from racing speed when passing the rescue boat. Failure to do so will incur penalties. There should be a ‘dead man’s’ handle fitted to outboard engines wherever possible.
13.9 Where practicable, the rescue boat is to be equipped with 2-way radio in order to communicate with ODD or deputy on shore.
13.10 When the end of the race signal is sounded, the boats will complete the lap they are on before returning to the pits in a safe manner, cutting the course will draw a penalty.
13.11 The overall winner is the person who has the highest laps in combined heats. In the case of a draw the Championship points will be given as equal in the higher position…eg Boats finish equal third…10 points will be awarded to both. If a trophy position is at stake then this will be decided by the flip of a coin or at the agreement between the drivers. If in the case of a draw in the overall Highest laps of the day, it will be given in favour of the boat in the lower class.
14. Sprint Race Event
14.1.Sprint cousre to be laid the same or similar to an endurance race or at the discretion of the OOD.
14.2 Boats to be timed individually around 5 laps of the course with start and finish being the same marker.
14.3 Competitors will be given 5 minutes to start and complete the 5 lap sprint. A maximum of 2 laps will be allowed as warm up laps.
14.4 Two stoppages (or at the OOD’s Discretion) during the timed section will be allowed. Once the boat stops the clock will stop until the model is recovered. When the boat returns to the water the clock will restart when it again passes the start marker. Only full laps will count towards the final time. eg if a boat stops 2.5 laps into it’s time the half lap will not count on re-starting, it must then travel 3 further full laps.
14.5 If a competitor decides to pit the boat during the timed section the clock will continue until the engine has stopped or is out of the water. If the engine remains running the clock with remain running.
14.6 If the set time limit is up and the boat is still on course it may complete the required laps and be given a time. If however it stops after the expired time limit it will not be allowed to re-start and be given a DNF (did not finish).
14.7 The intention of this type of racing is to be quite a relaxed affair. The discretion of the OOD/race organiser shall apply to all aspects of the race.
14.8 Championship points will be awarded for these events.
15. Driving infractions
15.1 The following rules are mandatory. Disregard of them will be judged to be an infraction and will result in a warning, lap deduction, heat or race penalties or disqualification.
15.2 All competitors are to race with due regard for safety at all times.
15.3 Deliberate obstruction, zigzagging, or overtaking in such a way that avoiding action has to be taken will draw a penalty.
15.4 The natural race lane is the lane that is nearest the course line and is considered to approximately 1 metre wide. This lane has the right of way at all times. The right of way principle also applies at all turns.
Any boat wishing to overtake to occupy the race lane must establish a minimum safe distance of three boat lengths in front of the boat passed before gaining the right to that lane. Any boat going wide forfeits its right to the race lane.
Infractions of the above rules will normally incur penalties as follows; –
Hitting the rescue boat at ANY time during the day – immediate disqualification.
Cutting the course on mill start or end of race. – 5 lap deduction.
– 1st offence a warning.
– 2nd offence 5 laps deduction.
– 3rd offence disqualification.
15.6 Any buoy missed during the race must be re-circled safely by turning inside the course; otherwise the lap will not count. The Officer Of The Day may advise drivers to miss buoys during the race on the grounds of safety; there will be no penalty for this.
15.7 If a driver is disqualified he is to be advised as soon as possible at which time he must be able to acknowledge the fact and immediately remove his model from the water. Disqualification means that the offending driver may take no further part in this class in this event and that any lap or time score achieved so far is disregarded. (The boat may still be run again by a non-offending junior or guardian).
15.8 If, in the opinion of the rescue crew or the OOD, a model is driven too close to the rescue boat or in a manner that endangers them, then the OOD shall disqualify that driver and model immediately. If the driver continues to drive in different classes in a similar manner, then that driver can be banned for the whole meeting.
15.9 If, during a heat, if a competitors boat hits a dead boat* at full throttle without noticeably throttling back or taking evasive action, a 5 lap penalty may be applied. [*This does not refer to boats which have either spun or stopped immediately in front of the boat which collides with it, but applies to boats which have been dead in the water for a period].
16. Championship Scores
16.1 Championship points will be awarded at all championship events to OMRA members only if championship legal i.e. if models conform to the Model Specification.
16.2 Points are awarded as follows:-
Countback. (reintroduced following 2016 AGM)
Count back is where the finishing order is recorded and in the event of a tied laps scores the boat with the least count back recorded is the winner. Where tied lap scores over two heats occur, the total countbacks for each racer over the two heats are evaluated. The racer with the lowest total count back score wins.
16.3 Disqualification means no points are awarded.
16.4 The number of championship rounds/scores to count towards the championship will be set at the Annual General Meeting proceeding the championship season.
16.5 The following trophies to be awarded at all championship events: –
– Fastest time/Highest laps of the day.
– Concourse d’elegance.
– 1st, 2nd, & 3rd. for each class.
