OFFICERS As previously mentioned in the December “Stop Press”, two changes in the Executive Officers took place after the positions of Vice-Chairman and General Secretary were contested by new candidates. The General Meeting obviously considered that had come for a change in these Colsell as Vice-Chairman. offices. Accordingly, the time Chris Jackson replaces Clive General Secretary Roy Gardner stepped down in favour of Russell Potts after 16 years of conscientious and valued service to the Association, for which grateful thanks are due and which will no doubt be recognised in due course Peter Maskell has taken over as Racing Secretary after the retirement of Jack Lee. MOTIONS AND AMENDMENTS (1) CONSTITUTION There have been some carrying of all important seven motions General Meetings, changes in the Constitution resulting from the amending Rule 7, which governs voting procedures at which effectively means that in future:-— (1) Representatives may be appointed by each affiliated club.

There was a full attendance and the Chairman welcomed the new members – Peter Maskell (Racing Secretary), Geoff Lambert (E. District) and David Trippe (S.W. District). RADIO FREQUENCY ALLOCATION Under matters arising from the September, 1984 Council Meeting, the Secretary reported that since giving the MYA’s approval to the draft submission of the Joint Radio Users’ Committee to the Department of Trade and Industry for additional frequencies for surface models, there has been a certain amount of dissention from the S.M.A.E. They have expressed dissatisfaction with the draft and have been in direct contact with the D.T.I., who have understandably declined to negotiate further until the J.R.U.C. and S.M.A.E. have sorted out their differences. Any future developments on this issue will be fully reported. 1985 YEARBOOK Council expressed strong dissatisfaction over the delay in the publication of the Yearbook, which the Publicity Officer assured the meeting would be ready for distribution within a few days. It was resolved not to employ the same printer again and apologies for the delay are extended to all clubs and individual members. RADIO SECRETARY Mr D. Blundell was elected Radio Secretary to succeed Russell Potts. His address is:- 96, Laneside, New Mills, Stockport, Cheshire, SK12 4LU. Tel: 0663 44187, FINANCE The Treasurer reported that 39 clubs had paid their affiliation fees to date and the resulting income shows an increase of £28 compared with 1984. The outstanding Registration Fees noted at the A.G.M. had been received. “MODEL BOATS” & “LOGBOOK” ARTICLES Council agreed that the views expressed in the December, 1984 and February, 1985 issues did not necessarily reflect the views of either the Council or the Association. Therefore the magazine has been requested to amend the heading of future articles to “Model Yachting News”, omitting the word “Association”. RM NATIONAL CHAMPIONSHIP, 1986 It was confirmed that this event would be held at Fleetwood again at Easter, 1986 and would be the means whereby the selection of MYA entries to the World Championship in the following July could be made from the results. DISTRICT CHAMPIONSHIPS Following a proposal from Chelmsford R.Y.C., it was agreed to attempt to standardise the dates of District Championships for the RM Class only in 1986. INTERNATIONAL YACHT RACING RULES & APPENDIX It was agreed that the new IMYRU RC Yacht Racing Rules Appendix will be used in conjunction with the 1985/88 International Yacht Racing Union Rules and will remain unchanged for the next four years. In future it will be necessary to purchase a copy of the IYRU Rules (to be published in March) from a yachting book supplier and then apply the Appendix for radio yachts, which will be available from the MYA Publications Secretary as soon as it has been checked and printed. Meanwhile, the current MYA Radio Racing Rules may still be used as the main changes in IYRU Rules consist of re-numbering to a more logical sequence. The Appendix will be sent out automatically to anyone requesting rules from the Publications Secretary but it may not be available before April, 1985. uw Re ) (4) 10 RATER CLASS RATING RULE (Cont. NEW AFFILIATION A newly-formed club, Platt Fields (Manchester) M.B.C., has been accepted into membership.

Will anyone owning a model with an interesting or outstanding history in any of the recognised classes and who would be prepared to part with the model either on a temporary or permanent basis, please contact Russell Potts. INDIVIDUAL MEMBERS In future, Individual Members of the Association will be issued with a long form of receipt for their subscriptions, containing details of their Insurance cover. REPRINTING OF THE MYA CONSTITUTION, COMPETITION AND VANE RACING RULES Priority will be given to re-printing the Constitution which has been considerably amended over the years. The Competition Rules, which were extensively amended at the A.G.M., will also be re-printed, together with the Vane Racing Rules to reflect the new IMYRU version. These re-prints are bound to take time but an Addendum to the Competition Rules is available from the Publications Secretary now. GENERAL SECRETARY’S MINUTES, NOTICES AND ACQUAINTS In view of the fact that the duplicator used for printing these items is no longer serviceable, it was agreed to hire a photo-copier on a “cost of paper and per copy” agreement only and the Secretary will be using his own word-processor for the original copies. BADGES, TIES, Volunteers, CAR AND BOAT STICKERS, SWEAT SHIRTS one from each District, are required to hold stocks of these items and to fulfil orders by post and carry small stocks of each item when attending open events. Please contact the General Secretary if you wish to help. Norman Hatfield, Chairman.

The future printing format for rules was agreed and the new 6 Metre Rating Rules and Certificates will be printed as The Committee endorsed the Chairman’s reply to the Australian M.Y.A. interpretation of Clause “supporting spar” rod soon as possible. and does not 13 of the ‘A’ in the new second include a jib boom. Class Rating Rules, sentence of the It was, regarding the to the effect that clause refers only to the however, the luff agreed that the wording of the rule is a little ambiguous and could be improved by the deletion of the word “any” in the text. NAVIGA The Chairman reported that, as agreed at the 1984 General Meeting, IMYRU Marblehead and 10 Rater Class Rating Rules had been sent to copies of the Naviga, together NAVIGA (Cont. ) with copies of the Union’s Constitution, Racing Rules Appendix, R.C. Yacht Racing System, Competition Rules and Rating Regulations. The Committee felt unable to accede to Naviga’s request to change the date of the 1986 RM World Championship to avoid clashing with their own Championships in Kishinev (U.S.S.R.) near the Roumanian border. WEST GERMANY The Chairman informed the Committee about the various problems relating to model yachting in West Germany, Where the Naviga~-affiliated organisation, Nauticus, has the majority membership. However, a new IMYRU affiliated club, the Vereinigung der Modellyachtsegler e.V. (VDMYS) was formed in 1983 and is affiliated to the fullsize National Authority of the Federal Republic, the Deutscher Segler—Verband, (D.S.V.). Model yachting has been placed under the wing of the Cruising Section with a newly-appointed co-ordinator, Gerhard Mentges, Kronskamp 26, 2000 Wedel. He is a young and enthusiastic model yachtsman who is keen to encourage the use of IMYRU rules and procedures in West Germany. One important advantage of joining up with the D.S.V. is that the VDMYS has received its annual entitlement of funds for administration purposes, part of which has been used to publish an excellent booklet giving information about model yachting in the D.S.V. The booklet was prepared by Horst Kronke in time for the Dusseldorf Boat Show. RM WORLD CHAMPIONSHIP, 1986 A firm decision was reached not to attempt to run concurrently a similar event for the Rl0r Class. Russell Potts will be acting as Regatta Secretary for the M.Y.A. Organisational details were discussed and the following agreed:— (1) The maximum number of entries will be between 72/80. (2) Allocations to individual member countries will be pro rata to their registered fleet returns as at 31st December, 1984. (3) (4) (5) The number of starters in each race will be limited to a maximum of 10. Entry fee to be minimum £25 with a levy of £5 to IMYRU funds. If possible, the Chairman of the Protest Committee should be an IYRU International Judge. Also, if possible, Race Judges/Observers should include members from different countries, provided they speak English. OTHER WORLD CHAMPIONSHIPS No applications have been received to host other IMYRU World Championships. Applications are invited from member countries to host a World Championship for the R10r Class in 1986/87. PERTH, 1987 Following correspondence between the Chairman and the President of the West Australian M.Y.A., Eric Fisher and the Australian ECl2m Class Secretary, Max Lewis, it was agreed to invite the Australian M.Y.A. to host an event associated with the 1987 America’s Cup Defence at Perth. The W.A.M.Y.A. has already proposed that, in view of the fact that the Americans have declined to allow the “Mini-—America’s Cup” to be competed for in Perth, a new trophy should be presented to be called the “IMYRU R.C. America’s Cup” and the Royal Perth Y.C. has confirmed that there would be no objection to using this title. The contest for the oup would be for match racing only but if, as is expected, the chosen olass is the ECl2m, it has been suggested that the event could be combined with a World Championship for the class, the award being the “Nepean Heritage Cup”. Norman Hatfield, Chairman. letters. HANDICAP SYSTEMS FOR MODEL YACHTS Jan Dejmo writes in MYN 19 about the Leading Yardstick System of handicapping between classes of yachts and its application to models. It looks as if LYS is similar in concept to the Portsmouth Yardstick used to handicap dinghies and small keel boats in the UK. As such, it depends on an adequate and representative series of results being available to enable the Yardstick to reflect the average differences in performance between classes. This is hard to achieve and, if it is achieved, the handicap is so averaged out that on any single day, under a single set of weather conditions, it does not iron out the differences between classes, and we are back with the procession that is the usual result in races with mixed fleets. In my own club, we have had experience of sailing M’s with, on the one hand 1.5 metre One Designs, and on the other with 36R. In each case the result depended entirely on the wind strength at the time, and it is hard to see how any single handicap figure would have coped on a single day, which is what the average club is concerned about when sailing among themselves. Indeed, given the wide variation of skill and experience within a club, a handicap system to iron out differences in performances within a single class is what most clubs need. This can take the crude form of starting the winner of the first race 20 seconds late in the next race, or it can be based on a data bank of previous results such as is used by the Condor (One Design) catamaran class association. This enables them to award prizes for the most as well as for the outright winner of their major events. improved performance RUSSELL POTTS Although I agree on most statements Mr. Osborne makes in his article in MYN nr.19, I disagree with his opinion that schedule racing is the best for the domestic one-day meetings. 1. This system needs preparation so that entries must be received at least 3 to 4 days before the meeting. All day reality (at least skippers check their racing-calendar on Saturday and club secretary next day.

The advantages of the schedule system in this respect are that the skippers are much more at ease. They know when they must take part in a race without having the change of being bounced up and down between two or three fleets and having to race under the constant meeting. stress of fear for degradation, which is very important for a friendly For the National Championship RM-class of last year, we made use of the mixture of both schedules as used at the World Championships at Dunkirk, and, in a way, at the European Championship in Sweden. This system gives the advantage of a peaceful selection and, after that, Besides those systems, the “real race” with the we also organize two fleet system. one-hour races. We cannot say that one system is more ideal than another but we do know that in this way, we give our members a variety of possibilities. One is in favour of one system, the next in favour of the other, but most important is that they are all content. of course I do make sure that the entrants know which system is being used before they enter. For our International “Molenplastrophy Regatta” (two days) we always use the schedule system. We usually have about 32 skippers and they sail in 8 boat races. Up till now, we managed to sail the 32 x 8 schedule twice so that each skipper races 16 times in two days.

SWING RIGS AND THE REINVENTION OF THE WHEEL Cyril Gould’s letter (MYN 19) rightly draws attention to John Pearce’s use of a swing rig in the early 1970’s and reminds us that there are few really new ideas under the sun. In my work on the history of model yachting, I have come across several examples of design and rig innovations which have been developed by individuals with some success, reported but not taken up, forgotten and later reinvented. Loose footed sails are a case in point; strongly recommended in the earliest ‘how to’ book, (J E Walton: ‘Model Sailing Yachts’ 1879), on the basis of carefully conducted trials and observations, they were not generally adopted by model yachtsmen until after 1945. Returning I have to the Swing Rig, there are two prior invention claimants that so far come across. An unnamed Yugoslav, whose design for a l-metre boat ‘Aero’ was published in the 1957 ‘Model Maker Handbook’, it shows a sophisticated fully battened main on what appears to be a revolving streamlined mast, together with an overlapping jib tacked to the fore end of a boom that is no forestay between mast and continuous deck and the sheet swinging boom. 12 with the main boom. lead There is is to forward end of the Frank Behenna, a a naval officer and model yachtsman who was he was founder member of the the Portsmouth club and of the Engineer’ Vol 29, Port of Plymouth MYC, MYRA and MYA in to about the competition. was bigger than the jib. and Plymouth on his and the (‘Model in Britain as a vehicle The rule prohibited the use of a spinnaker which a described a rig which he had experimented with ‘some years ago’ at 5-rater ‘Olga’. projection to the main boom, extending forward. opposite side, with two clips curving round the The foresail was unhooked from the bowsprit and spar at the foot of the projection of the main boom, that whatever side the 1913, Behenna reasoned that he might as well use the jib the after end of the to A stalwart of as ‘.eea brass mast In when p 380) he commented on the sail area restrictions in the French international spinnaker from 1892, 1939. 20’s. 80cm Rule which was then being taken up by keen modellers for active clips thus making it a continuation of it, the main boom swung, as a spinnaker. same was connected by the the foresail, being smaller, The boat ran quite well, was so set using a weighted tiller on deck’ It’ seems the boat report, was that this arrangement was only used on the off conventionally rigged for windward sailing. and as it is reported as an old experiment, notably more successful wind legs, and There is no further we must assume that it was not than the conventional rigs of the time. RUSSELL POTTS The yacht Revolver close hauled … under scudding sails I have seen with some curiosity the arguments of Mr. Gould, who if I remember, has produced several freelance good boats at the beginning of the RC era. I send you some papers that demonstrate that besides the very traditional balanced lug, the swing rig is quite old. Some interesting variationns are found in A.Y.R.S. papers also. But you are right to say that Stollery has developed the rig very far, and has produced a manageable rig, from the very smal model yachts (half size Bloodaxes) to the John Cleave’s no.6 Redwing, via Marbleheads, Ten Raters and a modified “Mirror” dinghy. I think that we have (yourself and myself, other people also) to say that Stollery has the genius to produce simpler and yet effictent boats: rigging bottle screws obsolete obsolete (only screw/nut at top of a pair of shrouds) backstay (alloy tube – stay on A boats), kicking strap – standing rigging – a sheet obsolete on new versions of the swing rig, and yet the boats with such devices are fast, not only in the hands of Stollery but also in many other skippers’ hands. And we have to remember the shock produced by the tube-hulls etc.) the in GRP, (freeboard-cheating perhaps) (White Rabbit, very light clockwork orange, developed by Stollery and Shepherd (another S & S). If anybody is yet contesting the name of Stollery Swing Rig and of Redwing simpler to mould and the simple plywood boats “Square One”…and their rounded chine variations, simpler, March Hare and yet efficient, it is the Red Rig), unstayed Stollery Swing Rig so better S,U.S.R.

Analysis of the results shows that those who excel at this unusual method of Radio Yacht Racing had a distinct advantage. To such an extent that the nineteen nine boat races forming the schedule section of the competition did little but split the ties present on completion of the match racing. best skipper won but what of those behind him? There can be no doubt that the The hard luck story in both the 1983 event as well as the 1984 Champions Cup just has to be that of the winner of the Schedule section. Barry Jackson won it in ’83 and David Andrews in 1984; coincidently both were in seventh place at the end Neither improved their position much by winning the second of the Match Racing. section. Can there be a way of scoring the two sections of the event which gives a more equitable result? I, and others, pondered this question following last year’s event and again this year. A number of different ways of scoring have been suggested, for example this year’s method was different to that used last year. I would like to suggest another method which, when applied to the races of 1983 and 1984, appears to produce a more evenly weighted result. Firstly, the basic premise is that expertise in one or the other of the two forms of racing should not bestow a particular advantage to a skipper. Therefore any method of scoring and computing an overall result should be easy to use and seen to be fair. Secondly, the method of scoring for Fleet or Schedule racing, 3/4 of a point for a win and points equal to places thereafter, has been used for some considerable time. Consequently it has a reasonable level of credibility and is understood and accepted by the majority of skippers. This makes it a good base upon which to build a system. Thirdly, that achieving 100%, or as near as one can get, is well accepted as being a winning ‘score’. Therefore a way should be found to convert a ‘minimum! score of points (number of races times 3/4) into 100%. Also we should compute the maximum score, worst case, and make this 0%. The numerical difference between the two will then be the central part in computing the resulting percentages. An example will perhaps serve to clarify the proposal. In the Champions Cup there were nineteen entries: more importantly, there were nine boats in each race and nine races per skipper. Thus the best score that any one could achieve was nine times 3/4 or 6.75 points: ie a win in every one of that skipper’s races. The worst possible score was nine times eleven points, achieved by being disqualified in every one of a skipper’s races. Using the regulation ‘size of fleet plus two’ points in every race to get a total of 99 points. This range A way from 99 points to 6.75 points is turned around into a range of 0% to 100%. of doing this is to use the formula:- ((maximum possible score)-(actual score))divided by(the difference between maximum and minimum) all multiplied by 100 to produce a percentage figure. Thus: nine wins = 6.75 insert (( into 99 formula )-(€ 6.75 ))/(99-6.75) = 92.75/92.75 = 1 = 100% ((max. poss)-(actual)) / (max-min) or: (¢ actual 99 score = 27.75 )-(27.75 ))/(99-6.75) = 61.25/92.75 = 0.7724 = 77.24% So much for the Fleet or Schedule racing, what about the Match racing? Last year I proposed that a system be adopted whereby the winner of a match race would be awarded 2.2 points, the ‘clean’ loser 1 point and the ‘dirty’ or penalised loser 0 points. entries, would score 1 In addition a bye, because of an odd number of point. a¢ MYA Champions Cup Scoring by M J Kemp for MYN At that time spreadsheet the scoring was juggling that I suggested did with Page on the basis the 1983 Milton Keynes Club has had of 2 some electronic Champscup scores. Since then the the opportunity to run a whole winter series of match races using a version of this points system. The variation is that rather than operate the penalty turns all or for nothing system infringements of disqualification thus effectively situation. for penalty, we allow scrubbing the zero point The result has been quite successful, accurately indicating the sailing abilities of the participants. Once again a percentage score is created by comparing a skipper’s score with the theoretical maximum. Thus we have two systems which produce a like result: in the same way that, at school, we used to add apples to apples but not to oranges. The overall result is a better balanced set of placings compared to the actuals for 1984. I have omitted the names to avoid too much embarrassment to those competing. If you want to know more you will have to work it ACTUAL 0/A 1984 out for yourself or contact me direct.
