4. Duties
4.1 Apart from the meeting O.O.D all other duties will be agreed on the day on completion of the Duty Roster. Any skipper who finds they are unable to “do their duty” must themselves find someone else to take their place. They can do this as many times as they wish, but if the replacement fails to show they will be held responsible.4.2 Race Officials: There must be a minimum of four race officials for any race. A Race Officer, Lap Counter, Lap Caller and a Race Observer (duties listed below). Additional Race Observers can be used if required by the Race Officer if the number of entries allow. Any Race Official can disqualify a driver/boat (see rule 16.10) for driving in a manner which causes wildlife distress and/or hits any wildlife at any time during a meeting.
4.3 Race Officer; Is responsible for over seeing a specific race and/or heat (as per Duty Roster). Must call all skippers for the race start, and will decide if there is to be any delay to the start. Will start the race with a verbal warning signal of between 5 to 10 seconds and will then start the race by sounding the appropriate start whistle/signal. Must also give warning of any dead boats or wildlife on the course (see rules 16.6 and 16.10) and record all the competitors lap score from the lap counter at the end of the race. The Race Officer will decide if a race is to be stopped early or abandon and together with the O.O.D can disqualify any competitor from a race and or the meeting. Will record all laps scored and finishing times, adding any penalties for missed buoys.
4.4 Lap Counter; Check the lap counter is set and displays the correct numbers. Records laps completed by all boats as called by the “Lap Caller”
4.5 Lap Caller Calls clearly all the boats as they pass the start/finish line and decides if any boats have jumped the start.
4.6 Race Observer: Will note any boats which miss buoys and inform the Race Officer at the end of the race. Assist in warning of any dead boats and any wildlife on or near to the race course.
5. Race Assistants (not Race Officials)
5.1 Rescue Boat (if the numbers of entries allows) Is ready at all times during a race to rescue any boats. All occupants MUST always wear a life jacket and comply with the host club rules regarding the use of the rescue boat. Must not launch during a race unless the Race Officer agrees5.2 Wildlife feeder (if the numbers of entries allows) Will feed any wildlife birds just before a race heat starts to encourage them to clear the racing course.
6. Boat Classes
6.1 All boats must be fitted with a “safety loop” colour red outside the hull, which when pulled will disconnect the battery supply to the motor. The loop must be fitted outside the hull in a position which is easily accessible to disconnect. For boats with surface drive or exposed propeller systems the safety loop must be at a safe distance away from the propeller blades. The loop itself must have a diameter of at least 20mm.6.2 Boats must carry an upright number plate, the number figure must be black with the lines at least 8mm in width on a white background at least 75mm high x 50mm wide. The number for each boat class will be the final placing the entrant achieved in that class, in the previous years SWAMBC Championship. New entrants to a class must contact the SWAMBC Competition Secretary who will allocate the next available number.
6.3 Any material may be used in the hull construction in all classes (It is strongly recommended that suitable flotation is installed into all hulls)
7. R2R (Ready to Race)
This is designed as an entry level class. Anyone who races in this class at least once for three consecutive years (from 2009) or wins this class championship in any year (from 2009) will be ineligible to enter this class again. This class is for Semi scale fast electric kit boats only. The boat kit must not cost more than £140.00 (normal RRP) and must come complete with - Hull (any material, type or design), brushed electric motor, speed controller or switch unit, drive system/propeller shaft, rudder, propeller plus all the fittings such as motor mountings, couplings, etc, must all be included. Only the radio and batteries should be needed to get the boat on the water.7.1 Batteries: 6 max. sub “C” (43mm x 23mm nom.) Ni-cad or Nickel Metal Hydride cells Not to exceed 3300mh (as specified on the batteries)
7.2 Race duration is 5 minutes. All boats will start in a grid formation (see below) racing clockwise on a triangle course using the centre buoy and bottom two buoys of the “M” course.
7.3 To race in the R2R class you will need to add a safety loop (see rule 6.1) and number plate (see rule 6.2)
7.4 No modifications or additions to the original hull design, motor mount etc are allowed. Any broken parts that need to be replaced must be identical to parts to those that came with the original kit.
7.5 There are just three exceptions to this rule:
- 7.6 The original propeller may be replaced by any non metallic propeller.
- 7.7 A speed controller unit may be replaced with a similar controller or for a servo operated switch unit.

13. Starting area (Formula 2 and 3 ONLY)
There will be a designated starting area on the water to the left side of the bottom left hand buoy. This area will be made clear by the Race Officer at the first race for each class. On instruction of the Race Officer the boats will launch and must hold position in this area. The Race Officer will then give a warning that the race will start in the next 10 seconds (this is not a mill start). Boats will then race to the bottom right hand buoy and continue anti-clockwise around the “M” course”. Any boat which is outside this area will be deemed to have jumped the start and deducted 1 lap from their race score.14. Mill Time (FM4, Hydro 1 & Mono 1)
The Race Officer will call for the boats to start their mill time. They then have 10 seconds to circle around the bottom right hand buoy in a clock-wise direction. All boats must have launched and cleared the start/finish line area within the first 5 seconds; anyone that fails to do this must join in behind the last placed boat as the race starts. Boats may approach the start line at any speed, as the Race Officer counts down the mill time. No boat may stop dead in the water or cross the start line before the start is called, any boats that do, will have 1 lap deducted from their race score.15. Course/Race times
15.1 The course layout, size and position of the buoys will be decided by the meeting OOD and SWAMBC Comp’ Sec’ or his deputy.15.2 Booking in time from 9.30am, first race will start at 10.15am, providing the duty roster is completed and the meeting OOD is prepared. A skippers briefing is not requirement for every meeting, but the OOD may call for a skippers briefing at any time during the day for which all entries are required to attend.
15.3 The boats will be raced in order of: R2R, Formula 2, Formula 3, Formula 4, Hydro 1, Mono 1 classes.
15.4 A minimum of 45 minutes will be allowed for recharging of batteries in all classes.
16. Racing rules & Lap scoring
16.1 At least 1 race in any class must be completed at a meeting for the overall Championship points to be awarded. If 2 or more races have been completed the lowest race/lap score will be discarded from the day’s total score (ie best 3 from 4 or 2 from 3 races to count).16.2 If a boat misses a buoy it must continue to race, but will have 10 seconds penalty added to its race score. If a second buoy is missed during the same race another 10 second penalty will be added, thereafter one lap will be deducted for each and every missed buoy. (ie: 3 missed buoys would score a 1 lap, plus 20 second penalty) The Race Officer may have “Assistants” to help observe the race and note any missed buoys.
16.3 On hearing the race finish call/signal, competitors must continue to race to the start/finish line. The Lap Counter will immediately stop counting any boats. The race will continue for a maximum of 45 seconds when all boats will be timed (in seconds) as they cross the finishing line. The Race Officer, assisted by the Lap Caller and/or Lap Counter will record all finishing times and add an additional lap to all boats that cross the line within the 45 seconds. Any boat that fails to cross the finishing line within 45 seconds will be timed as 0 seconds or DNF (Did Not Finish) although their lap scores and any penalties during the race time will still be counted.
16.4 Places will be decided by the competitor who has the highest total lap score after a race discarded (see rule 23) If there is a tie for total laps scored, then the boat with the lower finishing times will be placed higher. If this score also ties, then the best discarded lap score and/or lower finishing times will decide the places. If all the lap scores and finishing times are tied then competitors are considered to be equally placed and will be awarded equal SWAMBC points.
16.5 The Race Office may have to stop a race early to clear the course of wildlife or recover a sinking boat. Depending on the circumstance the Race Officer will either ask competitors to stop their boats immediately and remove from them safely from the lake. In which case the full race may be re-run if time permits on the day. However, the Race Officer may stop timing the race and ask competitors to finish their lap and score as per rule 25. Once the lake is clear, the race will be restarted for the remaining time (including Mill Time) and the two race lap scores/finishing times will be added together.
16.6 If a boat stops on the water during a race, the skipper of that boat must give a verbal warning to the others still racing and make sure the Race Officer is aware of its position on the water. The Race Officer must repeat the warning clearly to all the other skippers of “a dead boat” giving its approximate position on the course.
16.7 Any boat which makes contact with a “dead boat” after it has been called by the Race Officer will be disqualified from the race and must withdraw immediately. This race (for the offending skipper) will score as 0 laps; however, this race may still be included as a discard from the day’s results.
16.8 If during a race a competitors boat “comes back to life” after it has been called as a “dead boat” it may continue to race. The skipper involved must give a clear verbal notice to the others still racing including the Race Officer who must also make the others aware that the dead boat has re-joined the race.
16.9 A boat can be retrieved if it’s near to the bank and then only if it is safe to do so. It can be re-launched to continue racing providing there are no approaching boats. The rescue boat must not be used to retrieve a boat in these circumstances. 16.10 The Race Officials will warn skippers of any wildlife on or near the racing course giving its approximate position. Drivers are required to take any suitable avoiding actions, such as a wider race line, slowing down so to leaving appropriate room to avoid hitting them or even causing them unnecessary distress. If this is not done any Race Official (not just the Race Officer) has the authority to require any driver to withdraw their boat immediately and they will be disqualified from that race. This race may still be included as a discard from the day’s results.
16.11 If any class has 8 or more entered on the day, the meeting OOD will split the boats into 2 heats. Should 7 or fewer boats enter or during the meeting a larger fleet is reduced due to retirements, the remaining boats will be put into one heat only providing the majority of entries agree.
16.12 A competitor may ask the Meeting OOD for the lap counting to be corrected if he/she thinks there has been a mistake during a race. The OOD may consult other competitors directly involved in the race, the Race Officer and the Lap Caller. He may adjust the lap counting score if he feels it’s necessary. His decision is final.
17. Overall Scoring
17.1 Points will be awarded depending on the finishing places at each round. The scoring for each round will be a s follows; 1st place 21 points, 2nd- 18, 3rd-16, and so on to 1 point for 18th or over places. In the event of a tie the competitor with the higher discarded race score will be placed.17.2 The Championship will be decided by the highest score from any 6 of the 7 rounds, except in the event of a tie, and then the higher discarded score wins. If these scores also tie, then a count-back system will be used on the most 1st places, then 2nd etc.
