GRAHAM BANTOCK An update on thts neglected class, in the year of thetr world champtonship, with some designs from vartous countries. When I wrote a page in the September 1985 edition of M.Y.N. on the apparent decline in the state of the 10 Rater fleets worldwide, I naturally got an immediate response from the class enthusiasts. I have now been able to collect together a number of different designs in photo and plan form, which allow the reader to compare the significantly varied approach that exists in different countries. To those who wrote immediately my column appeared I can only apologise for the delay in publication, but I believe the focus of a world championship next year may bring some attention back to the class, and there is time for the keen enthusiast to build a contender from one of the enclosed plans or details if they want to complete at top level. My general points have regrettably been confirmed by correspondents worldwide, report interest at a much lower level than in the M class, France had a well-supported national championship this year but something to do with the venue, small. who and the total numbers sailing this might have in most countries are Wolfgangsee regatta gave two days to 10 Rater class with only twenty boats, some of which were old and outclassed, as against 70 boats Australia has more interest but the A class is vying News from U.S.A. and Canada is sparse anthusiasm to compare with their in M class, in popularity there. in the extreme, but I don’t see any real 1 meter class and the M class.

Their lake was purpose-built for model yachting, approximately 200 yards by 5C yards. They use most of it so we needed to pass an eye-sight test first! The course was a figure of eight with the start and finish in thh middle. Skippers were selected for each race by the french ““grillhazard” method. All the names went into a hat; the first seven drawn were in the first race, the remainder in the second. Then all the names went back in the hat for another draw. In spite of this random selection we all managed to avoid changing frequencies throughout our nine races each day. There was some variation in the number of times one was drawn against a particular skipper. For me this was twelve times against one to five against another. the pleasure of third sailing ten times against Chris Dicks. One I had I even beat him into place. Saturday’s racing took place in hot sunshine with a steady S.E.wind. Alex Karl had trouble getting his new Scimitar to go. Roy Burgess did much better with Alex’s old Scimitar. water.

Four different hulls in the four top places seems to show there’ e edg the e hav y tel ini def s rig ngSwi . them n wee bet ose cho to h not muc to down-wind, but I fancy the un-stayed Laser-style rig to be just superior in windward. Nevertheless the margins are small. The most critical thing this class is to have exactly the right canvas for the wind conditions. To From time to time there are proposals to change the class in some way. to limit the sail area or the height of rigs or the number of rigs, or even the move towards the 36/600 class. Whilst it is sensible to keep an eye on cost of equipping a yacht, I believe that most of these proposals would be will s rig h wit ts men eri exp the of All s. clas que uni a e hav We al. ent rim det at succeed or fail on their intrinsic value and not on their ability to cheand a measurement rule.

The Technical Committee has promised to produce a draft rule for consideration and ratification at the IMYRU permanent committee meeting on 10/llth January 1987. A few supplementary questions will be circulated in the interim to clarify some points, especially on “grandfather” clauses. Contrary to views expressed elsewhere, Naviga have indicated their intention to adopt the same rule so that there will be one rule worldwide for international and regional events from early 1987. altered for domestic, Second point to remember is that no boat will have to be club or local events until the respective National Authority confirms acceptance and instructs its own members.

HULL Model yachts have several advantages over their full-sized counterparts:- a) They are much cheaper to build, b) For this reason a person can induloe his development ideas, and c) One keeps one’s rear-end dry. However, like full-sized yachting, to achieve success it is necessary to follow sound boat-buildino procedures and pay careful attention to all stages of construction. Certain rules apply:a) Light is Right. The jess weight one can achieve in the hull the more can be added to the ballast, giving a stiffer boat, b) Strength is important: wind is not scaled down to suit the model. c) Watertightness is next to godliness, which is the only other resort should your radio gear get so much as hint of moisture on a it. 99,9 of all cases of “interterence” or ‘malfunction® are the resuit of dampness and/or corrosion of the pluas and wiring. d) After some considerable experience one may possibly vary the desioner’s ideas to suit one’s self: in the meantime stick to the balance and dimensions exactly. e) Be very sure at al] times that integrity of centrelines, verticality and symmetry are maintained, f) Use slow-setting epoxy glue in preference to the quick-set variety, especially for the basic structure. HOBBYPOXY is very good, 0.K. Here we go. THE STAND No drawings have been made for the stand: design it yourself. It usually consists of two ’X’ trestles joined together about 450 apart with a couple of upholsterer’s webbing straps across the top. Make it high enough to leave the keel clear of the ground, and wide enough to support the boat well. Use hardwood, brass screws and tacks and glue in assembly, If you can, halve the joints together. It is worth doing a good job: the stand will then last the lifetime of the boat. THE HULL You have bought a G.R.P. hull. It looks something like F1IG.1 on DRG.NO.1 at the top left hand corner. START HERE. INWALES Use 3xémm spruce strips 1200 long. Glue a strip to one side of the hull internally, and hold in place whiie glueing as shown in FIG.2. If the hull curves in (tumbie-hone) or out (flare) allow one edge of the strip to protrude above the other so as to allow for later sanding of the finished imwale flat and flush with the hull. (FIG.2b) Proceed with the opposite side. Do not attempt to laminate one inwale completely before doing the other since you will lose symmetry in the hull. After all is dry, proceed with the next lamination in the same fashion. Place a similar laminated bearer across the inside of the transon. 20 :TETe TLProe Cert os WS NeW es i0ftomgalMGidahomectoOeLsAED)AROPMETR148GRYe168CPDUPGETERa)Sed(.6 saeGnrdigma yeniMONtyW e ak |odB‘truiyfags}daivpSRylro1ouiUlgV”nSSdO}H)IfYufbs‘ea,rvmMpYDaBu)Potye)1“s“sgaO1ng9Y0yp0p/4| oy me n STAM whe ; ¢ U=)cilyoresGWEAon3eS)safsppibhyypvooalte—Py yx ) w weirs ShiymieAnser 2m | Vi i | 1 | pfuo0sFiad opSiwvsapt u}nos3ait)y etete ar owe { hpyifaucgesn,f appBeuilk J Ha|eyt] | – T v DECK BEANS Use 3xi2nm spruce. Cut 7 beams carefully to length noting that the width of the hull must be maintained as shown on FI6.3. Notch them under the inwales and glue them in place. Note that those beams marked ‘A’ must be kept down by the thickness of the ply deck pieces to go on later (see “2mm PLY DECK PIECES” below). Fiberglass gussets at the deck-junction will add to overall strength. EXTRA_LANINATIONS ON TNUALE Add two additional laminations each side between the main deck beams as shown in SECTION 3a. These will provide anchorage for the stays later, so fit a strong gusset of fibreglass cloth and resin below and bond to hull sides (SECT.3a). LONGITUDINAL PLY PLANKS AND BOW BLOCK Make and fit the longitudinal ply planks out of dam x SOmm wide marine ply. Pin, glue and glass in place (FIG 3b). Renenber that the forward of the two planks will have to take considerable UPWARD strain from the jib/forestay. Nake and fit the bow block. MAKE SURE THAT THESE ARE EXACTLY OVER THE CENTRELINE AND TRUE FORE AND AFT. LONGITUDINAL KEEL BRACES Make these from two bits of éxl2mm spruce (or 2/3x12nm laminates). These will have to take SIDEWAYS strain, so apply glassfibre gussets to all corners. DOWNWARDS strain from the deck-mounted mast will be taken care of by the keel later. MAKE SURE THAT THESE ARE EXACTLY OVER THE CENTRELINE AND TRUE FORE AND AFT. They will be used to locate the keel later. AFT LONGITUDINAL DECK BEARERS Make and fit these next from 3×12 soruce. Strain on these is not huge, but ousset them all the same. MAKE SURE THAT THESE ARE EXACTLY OVER THE CENTRELINE AND TRUE FORE AND AFT. nn PLY DECK PIECES These can be cut out now to fit, but DO NOT GLUE IN YET. You can also use Imm or 1/16″ ply in which case the deckbeams must be adjusted to suit. You may find that it will be convenient to make your hatch at this stage, so that you can use it for marking the hole in the centre deck-piece. HATCH Everyone has his own ideas. The main features of a successful hatch are: a) It must be WATERTIGHT. b) It must be easily removeable. c) You must be able to get a hand into it. The WILLOW fridge-dish shown is easily obtainable from the 0.K., Checkers Etc. and fulfills all of the above requirements. It has “SEAL’N’SAVE FLAVOUR” embossed into the top. Never mind. It seals and saves your precious electronics! Cut off the rim as sham in FI6.4, turn it upside-down and fill the ‘U’-shaped surround with amix of glass tissue and EPOXY resin (F1G.4a). Use the rim to mark and cut the hole in the midships deck piece, and put the whole thing aside for later use. DO NOT GLUE IN YET. MAINSHEET EYE AND RUDDER TUBE You are now going to make your first fittings. Get hold of a suitable rod-tip fishing-eye (get the best vanadiunchrome Kind) about the size shown in FIG.5. Buy (from a hobby-shop) a 300mm length of hard brass tube with an internal diameter which is a tight fit over the fishing-eye. Pin and epoxy (or silver-solder) the eye into the tube as shown, cut to length and chamfer, You can paint the brass part, or you can have the whole thing re-chromed (if silver-soldered). Epoxy éam ply blocks to the underside of the longitudinal deck piece and the bottom of the boat, 39 ne et… -3- and drill them at a suitable angle so that the mainsheet eye assembly when inserted is at an angle with horizontal (F16.5a). Glue in the deck-piece but DO NOT GLUE EYE ASSEMBLY IN YET. Put it aside for now. the eye RUDDER TUBE Obtain (fron the same hobby-shop) a 300mm length of 3.9?mm (5/32″)dia. hard brass rod together with a 300mm length of tube as a sliding fit over the rod. Don’t worry, it comes like that. Put the rod aside for now. CAREFULLY mark and drill the hull ON THE CENTRELINE for the rudder tube. Insert the tube, make sure it is VERTICAL and mark and drill the approprate deck-piece. Glue on 6mm ply blocks as shown and drill them for the tube. Now glue on the deck piece, stern insert the rudder tube (with plenty of epoxy) and trim flush. Grease the shaft and insert it while the epoxy is drying so that the tube doesn’t get full of glue. The epoxy won’t stick to the grease (FIG.5a). KEEL Use MARINE ply. Most use 9mm thick (shown) but dm may do, although it might be a bit floppy. Fancy hollow keels are also used. Most of them give trouble sooner or later. Shown is a fixed keel, for simplicity. Removable keels are fine for travelling but harder to build. The part of Keel within the hull must be enclosed in a water-tight box if the keel the is to be removable. It is then secured by a stainless steel stud-bolt driven into the top of the keel and protruding through a hole in the deck, where it is secured wita nut and washer. Unless you are very careful, you could add a lot of weight. Let’s proceed with a fixed keel for now. Cut the keel to the shape shown in FIG.é6. You can taper the trailing edge slightly towards the bulb if your aesthetic sense is offended by a straight keel. Like fancy decoration, really it doesn’t help your speed. Working slowly and carefully, sand the underwater part of the keel to an airfoil section as shown in SECTION 6a. Use the exposed laminations of the ply to obtain symmetry. This airfoil section is important: flat plate keels don’t work well. Cut the slot for the bulb as shown. It should clear a Mé bolt. Cover both sides of the finished keel with one layer of glassfibre cloth, fill, sand and polish to a high finish. Put the kee! aside. LEAD BULB You are now about to become a foundry-man. Find a friend with a wood lathe and get him to turn a pattern to the approximate shape shown in FIG.7. Varnish and sand to high finish, Nake a casting box to the approximate dimensions shown in FIG.8 and not less than SOmm deep. Make this STRONGLY of scrap wood, Masonite etc. Buy some ROCKSET. You will need more than you think. You can pad it out with CLEAN plaster sand, but not more than 2:1. DO NOT USE CEMENT. It shrinks. Mix a stiffish paste of moulding out box. Grease the pattern well, and press it into the paste until ROCKSET and fill the it is exactly half submerged. Leave to dry THOROUGHLY. Remove the pattern and clean out the residual grease with petrol or meths. DRY THE MOULD AGAIN IN THE SUN, THERE 1S SEVERE DANGER OF EXPLOSION IF MOULTEN LEAD IS POURED INTO A DAMP MOULD! Steal an old aluminium pot fron your wife. Bend and bash it to the shape shown in FIG.8. Obtain about 5 Kgs (12 Ibs) of lead. Old pipes, flashings, fishing sinkers, shot and roofs of old churches are all suitable. Break or cut the lead into suitable chunks, send your wife out and melt the lead on the Kitchen stove. quite quickly. Skim off ‘dross’ Don’t worry, it does nelt with an old spoon. CAREFULLY pour the lead into the mould until the meniscus is above the surface. Allow to cool THOROUGHLY. TOUCHING HOT LEAD TO SEE IF IT IS COOL 1S SILLY AND PAINFUL! The lead should fall out of the mould when cool, since it shrinks a bit. Repeat the whole thing for the of the lead. File off menisci until over: it the wife gets hone! half leads mate together. Tape the 1/2 leads together. Drill a hole to clear a Né bolt where shown and countersink, The total little other lead should weigh about 4,7 Kgs (10,5 Ibs.). Don’t worry if it is a can be drilled out and the holes filled with epoxy putty. Put the lead aside, and clean up before 23 N FOR KEEL T_I HULL CUT SLO Carefully cut a slot in the hull for the keel as shown in FI6.9. MAKE SURE IT IS ON THE CENTRELINE AND TRUE FORE A AFT. SUSPENSION TEST FOR BALANCE Hang up the whole boat as shown in FIG.10. Use a straight-edge and spirit-level datum. Temporarily fix the keel in place strings until the establish a truly horizonti by letting the top of it protrude through the deck and running a pi through. Bolt the half-leads to each side of the keel. Drop a hanging to plumb-bob from the suspension point. Adjust boat is LEVEL. The plumb-bob will point to the CENTRE OF GRAVITY. This should be abou 527mm fron the transom. If it isn’t, adjust the position of the bulb using the slot, and repeat. Make sure level again. Fiddle about tt until all boat i is well. Mark the C of & on the deck. You should attempt to Keep this C of throughout the remainder of the construction. You will use this suspension method continuously unless you have pool. Even so, the suspension technique is probably more accurate. The lead is shown with its nose flush with the leading edge of the keel. Don’t worry if this doesn’t work out Prognathous (nose sticking out in ¢ront) and retronathous (keel sticking out ahead of lead) keels are althougn they might not look all Mark the location of the allowed, that marvellous, they are better than an unbalanced boat. keel relative to the half-leads-and file them out to fit the airfoil section. Bolt an screw them together and to the keel with STAINLESS STEEL bolts and screws. DO NOT USE BRASS. Electrolysis it an will ea in no time (FIG.11). Fill up cracks and blowholes with epoxy putty sand and paint the whole keel. GLATEX 8 give anice, durable finish, but is a bit heavy. Sprayed-on DUCO is also O.K. FIX KEEL _IN PLACE The whole Keel can now be fixed. Use pin method to hold in place while drying. Use suspension method to more check onc that everything is as it should be. Place glassfibre cloth gussets al] around keel at hull junction. Make thi: area quite strong: it supports the keel and mast. Trim off top of Keel flush with deck when dry (SECTION 3c). RUDDER Nab your previously obtained rudder-shaft, and drill it for pins as shown (FIGURE 12). These will stop the shaf from rotating without the rudder, and can be of brass, welding rod or stainless wire. Solder or epoxy them in place. Cut two rudder-cheeks from Imm ply. Cut and trim leading edge from 3xdmm spruce. Glue one cheek to shaft and leadinc edge. Glue on the other cheek. Bend cheeks around rudder shaft to form airfoil and glue trailing edges and pottm together (SECTION 12a). Allow to dry and fill with resin from the top. Sand and paint. GLUE _IN REST OF DECK Now that your keel is dry, you can trim off the bit sticking out with the pin through it, and glue the central in place. Do not glue either mainsheet eye or hatch deck rim yet, but you can place them in position to see how everything looks. It should all look like FIGURE 13. If not, go back and try to see what you have forgotten. Make the bow-bumper from an old flip-flop. It musn’t lengthen the boat more than 12,5am to comply with the Rules. Sand it to shape. This is actually quite difficult. Sand the whole deck smooth and flush to receive iron-on fabric deck. It is unwise to iron the deck on yet, as there are quite a few bits and pieces to fit inside tha boat much easier done while the deck is off. This is actually why you can’t glue in the mainsheet eye or hatch rim yet: it makes ironing-on difficult. You are now about half finished, Congratulations. Go and have a beer or three. The next thrilling installment will accompany drawing No.2. my RU> THE PERMANENT COMMITTEE President Jan Hallin, Gnistgatan 5p11l s 421 43 v Frélunda, Sweden Chairman Norman Hatfield, SSO 9XU England.

This consisted of 6 matters arising from the May meeting plus no fewer than 19 other matters requiring attention and discussion, All this had been set out in detail on 4 sides of A4, with comments by the Secretary on most of subjects for guidance of Council. As the main item requiring immediate attention was the ‘M’ Rule Questionnaire, the agenda looked like a Chairman’s nightmare! This meeting was, in fact, the last to be chaired by myself after serving 10 years as Chairman of the M.Y.A. and the last Council meeting I shall attend as a member after 40 years unbroken service, during which time I have only missed one meeting while in hospital. Surely this must be some sort of a record! Anyway, it cannot be said that I have been let off lightly at this last meeting. It meant six hours of intensive concentration under constant pressure to complete as much business as possible before members started to drift away to catch their trains. Serving the M.Y.A. for all those years has been hard work and not without its problems but, the whole, on it has been very rewarding and given me much pleasure. RADIO FREQUENCY POLICY The Radio Secretary, David Blundell, stated that the 40 MHz band had still not been legalised for use and therefore he had nothing further to report, Meanwhile, he stressed the importance of a competitor declaring all available frequencies when entering a major event and not just the minimum six required by rule. It was reported that ‘splits’ in the 27 MHz band are now almost impossible to obtain and are no longer being imported. EXHIBITIONS Advance information for your 1987 diaries:- Model Engineer Exhibition – 1st/8th January. ‘M’ Sailboat ’87 – 7th/8th March. RULE REVISION The response from clubs to the General Secretary’s request for replies to the Questionnaire was disappointing. 9 clubs and 2 individuals replied but only 7 clubs completed the questionnaires and only 3 bothered with the Addendum. However, the replies that were received were helpful in enabling Council to answer the questions and where clubs had made clear cut decisions, these were accepted without question. Otherwise, where voting was equal or nearly so, the relative questions were discussed in detail and voted upon. The Addendum was also voted upon and this, together with the main Questionnaire, has been returned to the Chairman of the IMYRU Technical Committee. It is expected that the new draft rules will be available for consideration by the IMYRU Permanent Committee in January. RM WORLD CHAMPIONSHIP A letter had been received from our Patron, H.R.H. Prince Philip, congratulating the Association upon the organisational success of the Championship. Certainly, even if most of the M.Y.A. skippers did not distinguish themselves in the racing, it was generally acknowledged that the organising committee and the host club had done a very good job and deserved to be highly commended for their efforts, as did the Regatta Secretary, Russell Potts, whose efficient handling of the preliminary stages contributed much to the overall success of the event. The Chairman of the Jury, Bryan Willis, also complimented the organisation and was impressed with the efficient race control and the excellent atmosphere. He has submitted a report which contains much useful advice and helpful criticism, which will be closely studied by the IMYRU Racing Rules Committee. Financially, well budgeted, the event was remarkably for the end result was a small credit balance after paying the IMYRU levy of £420, The Regatta Treasurer, David Rose, his very precise and careful is to be congratulated on accounting. Arising out of the discussion about the event was the selection procedure to be adopted for future World and Regional ee be restricted.Graham Bantock has given much 26 should the number of entrants thought to the question and produced proposals for a ranking system based on the same system as the M.Y.A. League. This system was approved by Council and details are given elsewhere in this issue of MYN. YACHTING MONTHLY CUP The Racing Secretary, Peter Maskell, reported that the new knockout format for this competition appeared to be well accepted by the competitors and therefore Council agreed that it should be continued for future years. IDENTIFICATION NUMBERS ON JIBS It is now generally accepted that registered numbers on mainsails are too small to be seen at a distance in radio racing. In recent years, competitors in National Championships have been allocated race numbers to display on both sides of jibs, which can more easily be seen by both race observers and competitors. This, however, is not entirely satisfactory because it has meant cutting out new sets of numbers for each event, which is an arduous task with multiple suits of sails, although some regular competitors have been able to retain the same numbers without duplication. Graham Bantock has now come up with suggestions for a standard system and details of this will be agreed and published in time for the 1987 season. “A’ CLASS WEIGHT PROVISIONS At this year’s RA Championship, all yachts were check weighed but it was found that only two out of the total entry of 13 conformed to their certificates! In the view of the 0.0.D., Graham Bantock, three yachts were probably hopelessly out of rating and he would have been justified in barring them from the event. In addition, rigorous application of the rules would have left only two competitors – a hopeless state of affairs. Graham has therefore provided a partial and possible solution to the problem of inaccurate weight by proposing rule changes which would permit a tolerance of plus or minus 0.1 kg (0.1 1b) from the weight recorded on the certificate, which would be taken to one place of decimals instead of three as at present. These proposals will require the attention of the IMYRU Technical Committee in due course. SIGNING OFF This is the last time I shall be writing this column but I shall continue to report IMYRU news as Chairman of the Permanent Committee. By the time this appears in print, I shall have retired from the chair at the A.G.M. and therefore take this opportunity to wish my successor the best of luck and a smooth passage in the future.

MIKE BEILRY ar We COMPARISON OF FLEET SCHEDULE SYSTEMS Until 1986 the two common methods used for scheduling racing in England have been the SCHEDULE system and the STOLLERY system. Both types are well known and no explanation is required here. In 1986 the GRILLHAZARD system was introduced for the first time after its use for a few years in France. In its simplest form this system produces fleets by some random selection method and ensures that over a period of time each competitor has the same probability of meeting each other competitor. Over a large number of races competitor will tend to meet each other competitor the same number of times the same way that out of 600 throws of a dice approximately 100 throws will In this sense it is much like a ‘PERFECT SCHEDULE’ regardless of the number each in much be sixes. of races. In June 1986 two British competitors experienced a fleet system used by organisers of the Molenplastrofie sailed at Spaarnwoude, Holland. This has similarities to both the GRILLHAZARD and STOLLERY systems. The DUTCH fleet system starts with equal sized fleets drawn at random (that is per the GRILLHAZARD system). For the second race the top boats of each fleet are grouped together in Fleet A, the next best boats from each fleet go into fleet B, the next best boats go into fleet C and the bottom boats go into fleet D (in a four fleet race for example). This is the same as the first selection stage of the Stollery fleet race after the seeding race, the differece being that scores for each fleet are the same i.e. 3/4 to 12 or whatever. From this point onwards the similarity ends as for the third race again the top boats from each fleet are grouped together. In this way a competitor who or near the top of the first fleet D race goes is good enough to finish at straight into fleet A AND SO ON FOR. ALL avBSEQUENT RACES €EXAMPLS Foe THESE FLEETS OF S\X Most people will be aware of a preference on the part of the TACHTS some competitors for, Schedule system over the Stollery system or vice versa.

Stollery and Dutch systems are preferred. For regattas of For this shor duration where perhaps only a relatively small number of races compared with the numbe r of competitors are possible, the Schedule and Grillhazard systems can lead to several of the strongest competitors each having relatively ‘easy’ races , perhaps meeting each of the other strongest competitors only once or even not at all. In these circumstances it is quite possible to have a large number of competitor s with the same ‘best’ score at the end of the day’s sailing. This situation then requires a means of resolution, which in practice is usually a sail off. At the end of a day’s racing where race time for each competitor has alrea dy been limited by the high number of entrants this is wasteful of time and due to the “sudden death’ nature of the method, nor particularly satisfactory either. For regattas of long duration where the number of races exceeds the number of entrants divided by half the fleet size, this bunching of competitors tends no longer to be a problem. Where regattas are of relatively short duration use of either the Dutch or preferably the Stollery system exposes the strongest competitors to their peers for the maximum amount of time. Any time spent necessarily resolving protests between roun ds may well be compensated for by avoiding having to split ties between top placed competitors at the end of the day’s racing. One other, perhaps the most significant, advantage of either of these two systems that entries can be taken virtually right up to the start gun for the first race, due to the removal of the necessity to pre-prepare schedules. This benefit could bring on average more competitors to our sport than a 10% increase in the model yachting fraternity at large could bring about – not a bad thing?

The wind was strong and from the With a very varied fleet regarding yacht design and date of construction some interesting comparisons were possible between what people were sailing in the 50’s 60’s 70’s as against the high tech yacht entered by Ron Leckie. Does any one remember for instance the “Manta”? That said, sailing was to a very high standard with no one yacht winning her heats by any great margin. was the very fine performance put up by John Mathieson of a yacht at championship level for some seven years. No Paisley who doubt John’s familiar to many of the Fleetwood Club members who may recall some time ago with considerable flair.

Anderson May Huntsman Johan ci NORWAY This year’s Norwegian Open RM Championship, held over the weekend of 16/17th August, enjoyed an international flavour, with three entries from Sweden, two from Belgium and one from England amongst the 20-boat fleet, the same total as last year. A heat system of two 10-boat fleets was again used, starting with a non-scoring seeding round, followed by 3-boat promotion and relegation thereafter. Six rounds were sailed on the Saturday in a predominantly light/moderate breeze. After a dry morning, rain set in after lunch, which made conditions rather unpleasant, so an early finish was very welcome for everyone, including Wendy Klem who had braved the elements and coped very well with a soggy score sheet. Sunday was a much more pleasant day but, although there was sufficient wind to provide close racing most of the time, it was rather shifty which meant several course changes. A further seven rounds were completed by 4 p.m. and the final result was that Torvald Klemregained the title he lost to Dick Eastwood from Hong Kong last year. His nil score, after discarding a third and sixth place, reflects not only the speed of ‘Lazy Lady’ in conditions which obviously quit her, but Torvald’s almost uncanny ability to make perfect starts nearly every time. Runner-up was Norman Hatfield with his new ‘Tornado’ design by Oliver Lee and the only boat with swing rig in the fleet. The speed of the boat down wind contributed to its generally good performance overall. The final scores in ‘A’ 1. 1. Klem N 5. M. Ténnesen (N 2. N. Hatfield 3. G, Karlsen 4. B.

The membership gives Finnish sailors full rights to participate in Scandinavian and international races. Model yachting is concentrated on the South Coast of Finland. The biggest clubs are Galltrisk Segelsdllskap and Miniveneilijat, located in the Helsinki metropolitan area. Scattered boats can be found in Hang, Borga and Tampere. The main activity is in radio-controlled Marblehead class boats. Sail numbers have reached 90, but only about ten boats are racing actively and seriously. The top boats are of the Canadian “Kisutch” design, while the Swedish Norlin 127 kit boats constitute the bulk of the fleet. The Finnish National Championship of 1986 was won by Christian Lindholm of GSS, using a self-built Kisutch with Kevlar hull, carbon fibre mast and Bantock sails. Four Finnish boats participated in the Scandinavian Championships in Kristianstad, Sweden. The top Finnish performer, Esa Anttila, did well in the strong winds with his low-rig Kisutch and finished fourth of of 26 participants. A few weeks before, Esa had finished fourth in the Naviga World Championships in Moscow. Plans for the winter include a racing rules seminar and the building of some new boats Sights are set upon participation in the to Canadian and Swedish designs. Scandiavian championships 1987 in Denmark, and possibly the Marblehead Europeans in Holland and the 10-R Worlds in Sweden. It has been agreed to arrange the 1988 Scandinavian Champs in Finland.

Providing Peter and Alex kept their heads they couldn’t be caught but the next half a dozen had everything to sail for. The Team Championship (three nominated boats per Club) was never closer than at the start of the last day with a handful of points covering the top three. One or two poorer trims were made which affected the prize order as at the end only 4 points covered the five places from third to seventh. The old sailing head on the young shoulders of Martin Roberts just kept him ahead of Bernie McNulty and Ray Baker, who had to sail off for fourth place, and the Rose/Reeves combination and Dave Potter. It was an exciting end to a very good week of sport. THE YACHTING MONTHLY CUP. Wednesday afternoon. With few outsiders daring to invade our shores with their “A” class yachts these days (Hughie Shields excepted – this was the 25th consecutive annual appearance for the Monarch of the Glenfiddich) it had been decided to try a new form of racing for this sought after trophy. Roy had elected to try a knock-out race with each pair of competitors having two beats, and a run if necessary. Everyone was delighted to be having a away with it. the jackpot for sail and there was a feeling that perhaps the top boats would not run The Open Race is won by consistency, but frequently someone can hit a day, and half a day would be enough. As we started the monsoon re-appeared and the first round was held in soaking rain. Sixteen skippers happily survived, though half of them had to endure a run as the beats were shared. No surprises yet. Still in the rain, half the second round pairs went to a run too, the racing was so close; some disappointment but still no real surprises. Then out came the sun and all the spectators and the surprises started, Lisa Reeves took Alex out and to prove that this was no fluke then knocked out Peter Maskell. Martin, Ray and Potter had all departed the hunt leaving Bernie to sail Lisa and Rose & Reeves (G) to sail the Portugese Pirate, Manuel Goncalves our remaining foreigner. The bubble burst at last and out went Lisa and so did her Dad All the competitors were still there to cheer the finalists along Dave Rose. and their way. Even with Walter Jones‘ long international racing experience helping him along Bernie could not get it quite right and so with great panache Manuel took the prize, helped along his way by Jim Weildon whose only other international experience was keeping the Computer Shed under control at the World’s RM. It had become a truly International Race after all. The Editor of Yachting Monthly, James Jermaine, had joined us at lunchtime and, notwithstanding the storm, had watched the competition all the way through and presented the Trophy to Manuel then and there. After the huge success of the event, one wonders whether there need to be any further experiments in its form.

Cole and Priestley swapped the lead several times between races 16 and 20, Priestley again falling foul of the Protest Jury. Towards the end of the day winds freshened and Dicks, Cole and Priestley continued to sail consistently, the last getting the better of conditions and never really being threatened for the lead once the wind picked up. The OOD included in the sailing instructions an amendment to IYRR 39 defining the “proper course’ as the’compass course to the next mark except in exceptional circumstances’. No incidents or protests concerning 39 occurred – but it is just possible this was a direct result! In offshore racing when out of sight of the marks of the course the compass course is naturally the only one which can realistically be construed as the proper course for the purpose of 39. Inshore racing, perhaps in a tideway, or a river, or around a bay where wind conditions vary dramatically with position there is often good reason to sail a course between marks which is not the shortest distance for other than tactical reasons. Reverting to the simple ‘offshore’ definition of ‘proper course’ for radio yachting makes sense when it is likely that the distance and duration of each leg of the course is stances (e.g.obstruction, major wind so short that, shift), During the regatta all yachts were weighed. except in exceptional circum- the compass course is the proper course.
