We can safely confirm that there will be enough demand to justify continuing and this copy will start the officiel subscription edition. Next issue will naturally feature the National events which will take place over the peak sailing period of the year, but we have also got a 10R design, kit review, several fitting sketches and some historic photos to fit into future editions. Please let us know your views on the content and style (preferably print able!) and we will try to respond. cover pic Issue Number 1 featured Oliver Lee’s 1.5m prototype sailing at Burnham-on Crouch, and Issue number 2 hes two R.M’s, a Chris Dicks’ Gaucho and German Klug, pictured at Ash by Tim Prior. subs For those who heve not already sent their money, subscriptions will run from June to larch which enables us to calculate our basic income once a year and plan ahead. 1980 subscription is £3.00 post paid U.K. £5.00 post paid abroad.

At Leicester eight boats appeared and found force 4 winds from the South, as true as possible on this water. In this windstrength reduced sail aree was clearly required but unfortunately Dave Hollom had left most of the 2nd. suits at the Dinghy Show stand the previous day. As a result two boats had a distinct advantage all day and came out winners. At Cleveland the host club asked 12 Mickey Finn owners to make their boats and radio gear available for all competitors to race and invitations sent to all Northern District clubs. It was thought that the idea of not having to prepare one’s own boat and to load it into the car with all its attendant paraphernalia and to the exclusion of other passengers might have its attractions. After a week of rain and gales, Sunday arrived bright and sunny with a moderate N.Westerly wind dying to very light by the end of the day’s racing. It was decided to race only 8 of the 12 boats available, each boat having a team of 2 helmsmen to race alternate races. A long course was set, having 5 beats, 4 reaches and 2 runs. A penalty of one 360 degrees turn for an infringement proved to be most acceptable and all incidents were resolved on the water. The duo of Barry Jackson (Ashton) and Martin Young (Killingworth) won the event with 143 points, and the best individual scores of helmsmen from each side of the border were used to decide the winner of the “Roses Match”; Barry Jackson (Lancastrian) 4; points, beating Dave Hollom (Naturalised Tyke) 72 points. Entry Fees of £16 were donated to the “Friends of Lionheart”. 1.5 METRE. The first official race held for this class was, not surprisingly, well attended with twelve entries. The Northerly wind meant that the course was in the lee of the bank where competitors launch their boats and although the wind was gusting up to force 4, the water was relatively smooth. 0.0.D. Arthur Ott, specified a course which gave a short fetch start, followed by a long downwind leg, a reach, a long fetch and a short fetch to finish. Starting and finishing in the lee of the bank caused problems — all competitors hed elected to use their lowest suits of sails and hence the yachts were very underpowered except when well out from the bank. The 0.0.D. had arranged for match racing to be employed, having two pairs on the go at a time, separated by a minute or so. Winning margins varied from 4 a boat’s length to as much as a leg of the course and it wes usually the boat which made the leeward buoy at the end of the run first that proved the winner. By the end of the day it was found boats had not sailed equal numbers of races and it was impossible to determine a winner using the scores to date (use of a vane—type schedule would have been the answer here!) and so the top six likely contenders took part in one six boat, sudden death, finish over two lengths of the course. Chris Eagle attained a clear lead over the remainder and hung on to win by a boat’s length from Dennis Graham. Norman Hatfield finished 3rd. after eventually breaking the cover of Oliver Lee, 4th, by virtue of boat speed, having tried various other methods e.g. denying an overlap call made about 20yards before a mark etc., chairman’s column The Association has received the honour of an invitation to send four representatives to 2 Royal Garden Party at Buckingham Palace in July. We understand that quotas are allotted on 2 rota basis to all organisations of which Prince Philip is Patron and it is our turn this year, when we will be represented by our President and Chairman, accompanied by their wives. We expect that there will be further invitations in future years, when other Officers of the Association will heave the opportunity to attend. Council meetings are normally held in January, May and September, with the A.G.!. at the end of November or beginning of December. So bearing in mind the deadline for Newsletter copy, readers can expect information from these meetings as follows:- March issue —- A.G.M. and January Council meeting.

On the Saturdey, which gave a Dave and Andrew Hollon, Eric Nuttall and John Cleave took part in pool demonstrations with “Mickey Finns”, which were an added attraction for the public when sailed by various personalities from the dinghy world. On the Sunday, Norman Hatfield, Oliver Lee and Norman Curtis provided “RYs” for the demonstration sessions. Business on the static display was brisk throughout the weekend and there were the usual numerous enquiries about Club locations, availability of boat kits, sails end fittings. We did, however, experience the seme problem of under—manning as with the Boat Show and M.E. Exhibition and, unless more club members are willing to volunteer to help at these Exhibitions, our future participation will be in jeopardy. This would mean the loss of fine opportunities for recruitment and the spread of interest in our sport. So may we make an urgent appeal for more assistance with the next round of Exhibitions.

The Association has donated £25. to the Trust Fund for this very worthwhile project. The lastest news is that the Trust now has a good chance of acquiring a site in Poole, which could be opened next year at a cost of under £250,000. The site has the attraction of being on the tourist map and also has the benefit of an on-site caretaker, thereby reducing running costs. We shell, of course, be offered space to mount a display depicting examples of model yachts of all classes, past and present. It is hoped that some well-known old models will be donated to the Nuseum for posterity. I.M.Y.R.U. News.

We hope to have fuller reports on these in due course, but the Dowling boat sounds particularly interesting in being multi-chine shape. CLAPHAM: Unfortunately the 24 hour race proposed by this club had to be cancelled because of a lack of entries. We are also told that although Chris. and Mark Dicks are sailing “Mickey Finns” there is no firm date set for an open race for the class. Vane sailing has almost ceased at the Long Pond whilst concentration is on tuning the R.M. boats that are going to Ottawa. EASTBOURNE: An appeal from Norman Sylvester who is also district committee secretary for clubs in the district, to let him know if they will welcome visitors to club races. With major open events becoming oversubscribed he feels that some newcomers may prefer to travel to other clubs on less formal events and wants to know if clubs will welcome then. GUILDFORD: Vane racing continues at this club but is now conducted at Stokes Park Guildford and Roseberry Park, Epsom where the water is more accessible than Elstead Moat. Our spy tells us that on a visit during the recent bank holiday he met four R.M. and several other radio boats, which is not bad considering the major event down the road at the New Forest on the same day. NEW FOREST: Strong reaction to the Newsletter from secretary, comments in his usual forceful style. Tim Fuller, who Very strong radio Marblehead club (with the Wilkinson Sword open event on June 22nd). R10R are also sailed. WOODLEY: Members recently mounted a display at a new venue where developers are utilizing grevel pit workings and encouraging sailboards, dinghy and model yacht sailing. further afield DENMARK: More than 50 R.M. class boats sail regularly with both German and Swedish fleets. We hear that an R.M. skipper has purchased spinnakers from a British sailmeker for immediate use! Jens Brandt (well known A Class skipper) is building a trio of new boats designed by Kai Ipsen, all appear at Gosport. for himself and friends. It will be interesting if they ITALY: “Bloodaxe” has been renamed “Cariatis”, Italian for stone, after its light weather performance had been compared with indigenous designs. Apparently shortage of modelling items we take for granted (eg. G.R.P. pigments, mast tube etc.,) are a problem, which is odd in a country noted for its high quality model makers and designers for cars, furniture and other consumer goods.

Reports of the Neviga/M.Y.A. Fleetwood week appear in a recent French language magazine.

They seemed to enjoy themselves however, and general impressions were favourable, race review It is not going to be possible to detail all events with a full result sheet because this would be of little general interest so we intend combining all the reports we receive into a more general review, detail only national and international championships. and 36R. The M & S district ran a vane race for this class at Clapham and 9 boats sailed. A glance at the results shows a master P. Stollery in third place (perhaps he had a good mate) and all the boats were of different designs. Winner, Alex Austin, sailed a round bilge conventional design, the Stollery boat was a “Square One” with revolving ring end fourth boat was diagonal planked in veneer and of maximum displacement with a very full bow section. RIOR. Midland District Championship, held at Lincoln, attracted 11 boats and winner was Alan Pollitt of Ashton. Slightly different idee to cut dom on time wasting, was the system of selecting 6 boats at random to start and then “one on and one off” until each boat had raced six times. Each boat got 12 races in the day which was the result of minimal handling. 10R VANE. M&S district team event combined with the Silver Ship Trophy was sailed at Eastbourne and had 10 boats in five teams. his own design rounded deck Des Daly sailed “Hiccup” to a one point win from Manuel Goncalves sailing a beautifully finished Crecker which was also feetured on the M.Y.A. stand at the Model Engineer Exhibition.

Now a traditional early season event, this year marred, we hear, by a “discussion” on the rules at the end of the day. Chris. Dicks again top, followed by a collection of Trappers, Seahorses, Challengers and Moonrakers. Incidentally this club has few active members and would welcome newcomers (contact Dave Brown, Basingstoke 770145). Apart from the Mickey Finn reports I have not received news of any Northern events, or for that matter, any races other than the above. No doubt the next issue will be fuller with the peak of the season about to start. Can we please have as much information on boats/design/construction as possible as we have had a number of comments about the lack of these details in other magazines. MI nats Fleetwood put on another excellent show, 0.0.D. Norman Jares taking firm control from the beginning, measuring all boets before the start and insisting on sail numbers etc., being visible. The wind blew straight (well almost!!) down the lake from the clubhouse for three days, moderating from force 5 on the Saturday requiring 3rd/4th suits on working rigs, to second suits on the Sunday and Monday. With bright sunshine ell day long it could hardly have been better, with the one problem that the bridge at the clubhouse end blanketed the starts of the runs and led to a few sad faces as the opposition stole awey on their own private breeze. 12 Bloodexes sailed (out of 26 entered) and three Sula designs by Bill Sykes were trying to emulate the original which won last year for Harold Dovey. Two designs more commonly seen with radio were Ashantis (Dave Hollon design) and a Chris Dicks’ original Frisky of which only three have ever been moulded. Keith Armour’s boet was double diayonel plenked in veneer by John Lund and weighs around 15 lbs. Des Daly had two of his own design boats sailing (Hamster and Hibiscus) but used a Bloodaxe, whilst Walter Jones’ boat was a development of I”-4-Sis with a pronounced fine entry and canoe stern, weighing 14 lbs. and carrying quite a high aspect rig. The winner, Dave Latham, was sailing a Fred Shepherd design constructed by Jim }ajor, moulded in one with a traditional flat deck, a flat run aft, slight flare on the bows end light weight. Combined with superb trims on the runs t is enabled him to take 90% of possible points to achieve a clear win. Boats: Skipper: Club: Design: Points: Place: Puddy K. Roberts Bloodaxe 4th. W.H.

With a newly built yacht, whether produced as a one-off or from a kit, it will be ncessary to tune the sailing trim in order to get the best possible performance. Even if yours is an example of a well tried and tested prototype the chances are that the small differences in rudder end keel profile and section, lead ballast, mast stiffness, sail cut etc., will compound together to produce a yacht with very different handling characteristics. Optimum mast position has been found to vary by as much as 1″ on “A” class yachts from the same mould and built as identically as practical considerations allow. Similar differences can be expected on “M” class yachts even when the builder has religiously followed the plens. If the yacht is a new design the mast position will have been arrived at by some form of more or less sophisticated guesswork, mathematical or otherwise, almost invariably based on past experience and comparison with other successful arrangements. Clubman hes met one full size yacht designer who determined his design’s mast position by comparison with the profile drawings of similar yachts in a yachting magazine’s advertisements. The process of tuning 2 yacht is principally geared towards obtaining the best possible speed made good to windward as this is of prime importance if the object is to win races. Yacht speed on a windward course is particularly sensitive to sail trin. The angle at which the wind strikes the sails may be as little as 4o° for windward sailing and should the trim of your sails be even 1 or 2° from the optimum, boat speed may be lowered to an uncompetitive level. On a reach, or a run the angle at which the wind strikes the sails may be from 20° and small departures from the optimum are much less critical. to 90° Happily a correctly tuned yacht, when sailing to windward, is usually in a form of stable equilibrium. If the wind heads even without corrective helm the yacht will usually heel less and pay off until it settles on its new course. If the wind frees, then the yacht will heel more, round up and eventually settle on its new course. Hence a correctly tuned yacht will sail itself to windward and will only deviate from the optimum trim and course when one or 2ll of, wind speed, wind direction and rudder angle changes. This state of equilibrium rarely exists for off-wind courses, but generally the sail trim is not so critical and it is of less relative importance, The flow diagram on the next pege illustrates the process of tuning a yacht to sail windward and is equally applicable to a vane or redio controlled yacht. Wost skippers of vane yachts will be familiar with the process of tuning for windwerd sailing with the rudder locked in a central position. This, however, is something few skippers of radio yachts appear to do, (except probably Nr. Quick) and is almost certainly as responsible for mediocre or variable performance as poor tactical ability. application of the tuning procedure may, at least, Careful eliminete some of the more basic falts of a yacht’s trim and will enable !’r.

Although Powerboaters and Yachtsmen may seem at times poles apart it is a fact that in both the M.Y.A. and the M.P.B.A. there are a number, a great number, of people who are interested in all forms of model boating and it is to our mutual advantage that such interests should be encouraged and that the two organisations should support one another. Nay I, on behalf of the M.P.B.A. and of course Naviga, wish you every success and if at any time there is some wey in which I can help you in your efforts please be free to call on me. Yours sincerely, Jim King, V.President. M.P.B.A. V. President Naviga. I have reed issue No.1 and would like to comment on Vic Smeed’s article. I egree with much of his argument and would like to suggest that an idea I was advocating some months ago in “Model Boats” “Log Book” would solve the problems. That is for li.Y.A. to recognise a “Free Formula” Class, where racing could be very loosely grouped in terms of s2il area, and hold a meeting in each M.Y.A. as area each year, publicising it as much as possible, a semi-educational thing. This would give satisfaction to local authorities who give grants under Sports Council Rules. If it attracts a lot of attention from parents and kids it can also give a hefty boost to club canteen funds, if clubs are as organised in that respect as Leeds & Bradford Model Racing Yacht Club (my club). My main interest is in experimental development of sailing boats and last Saturdey I tried out the result of a suggestion I made in my Model Boats article, of an extended Marblehead hull. It is a better sailer. With a “Clipper” bow and a fine tapered stern, with a considerable sheer on the deck, it is a very handsome little craft and the performance is very satisfying. Wore ebout this later when it is finished and tuned. (It will measure to the 10 Rater rule). David Boothroyd.

The incident being witnessed Both helmsmen, being incapable of finding a suitable right-of-way rule to substantiate a protest, decided against this action. A protest committee, hearing a protest lodged to comply with Rule Bilis were asked to find that the contact was minor and unavoidable. Questions:- 1) Can a protest committee dismiss a portest, without penalty to either yacht, when it is satisfied that the contact was minor and unavoidable? 2) If it is necessary for one of the yachts to be penalised, is the protest committee required to establish which yacht was at fault? 3) Can a protest committee recom.end that a race involving only two yechts, be re-sailed without penalty to either yacht? R.Y.A. Racing Rules Committee’s Answers:- Question 1) Yes, but only if the sole ground for the protest is that there has been contact between the yachts and neither has retired, exonerated herself by accepting an alternative penelty, or lodged a protest. Question 2) Yes. Question 3) Yes, but only if it rules that the finishing position of one or both of the yachts has been materially prejudiced within the provisions of rule 12, (Yacht Materially Prejudiced) or rule 68 (Protests) 10 raters Earlier in the year, Brian Barber, of the Leeds and Bredford Club started this association to improve awareness of both vane and In the last few years of vane racing 10R’s became that they became too quick for their crews and in out of thirty boats suffered severe damage during radio 10R boats. so fast on spinnaker runs one day at Hove ebout ten a National Championship. Now it seems that due to a clash of dates, the weekend of 18th/19th. October will see major events on the same day at Fleetwood, Birminghan and Hove with vane boats at two places end radio at Hove. At least it means that intending competitors have plenty of warning and spectators will, with luck, be able to see these boats at their best on seaside lakes in a good breeze. Other open events involving this class are on June 8th at Leicester and the 12th. October the Cheddar Cheese combines RA and R10R at Axbridge Resevoir organised by the Woodspring Club. More details from Brian, at, 243, Gibson Lane, Kippax, Near Leeds. odds & ends The American Model Yachting Association’s quarterly newsletter (distributed to each of the A.M.Y.A’s members) carries details of a radio Marblehead successfully employing a spinnaker. The canoe sterned “Epic” design fitted with the spinneker has a reputation for excellent light weather performance although its all up displacement of 16.5 lbs. seems high by British standards. However, this no doubt eased the sacrifice of 1 lb. of ballast to be replaced by two extra servos and one extra winch. One servo opens and shuts 2 sliding hatch cover forward of the jib pivot position through which the spinnaker is hoisted and retracted. The boom is rigged on the mast with the inboard end some 16″ plus up the mast. With the spinnaker down the boom pivots downwards clear of the jib. Fore end aft trim of the boom and spinnaker ( and choice of side) has to be decided before each race, the winch merely serving to hoist and lower the sail. Skipper and boat enjoyed ideal conditions for the first day’s racing. In light winds the boat was in leading position after 14 races. Finishing position after the next day’s racing was 3rd after increased wind strengths prevented the use of the spinnaker. Such a promising display can be expected to encourage wider experimentation with spinnakers in the U.S. probably with a considerable increase in excitement in lighter conditions. No mumblings about banning the use of a spinnaker are reported so far……. One motion to be put before the membership of the A.M.Y.A. A.G.M. is the adoption of the M.Y.A. class secretary, Chuck Black, at the 1980 (I.M.Y.R.U.) “!” Class rules. The who proposed the motion is seconded by a list of well known names including the President of the A.M.Y.A. and of the I.M.Y.R.U., teo designers and two sailmakers, and is to be congratulated for his action. Although the present A.M.Y.A. rules arebasically the same as ours, they are by no means as rigid. Successful adoption of the I.M.Y.R.U. rules will go a long way towards unifying madel yachting worldwide. on the agenda is a motion to adopt the U.S.R.Y.A. Also (R.Y.A.) rules regarding touching 2 mark. EUROPE/NAVIGA. the I.M.Y.R.U. Late last year it was understood that NAVIGA was to adopt “M” and “10R” class rules. Their “NY” class rules called for “fair even curve” roaches and their “10R” rules were based on the pre-1968 (pre Warlord)”10R” rules with various other restrictions on batton lengths. In fact Maurice Franck confirmed in December that I.M.Y.R.U. rules would take effect from January ist. 1980. onwards. “NM” and “10R” Now, rumours suggest that this is not the case and that the old versions of the rules still apply. It will be interesting to see how international competition in M.Y.A./ Naviga events develop, especially regarding the validity of rating certificates. Presumably I.M.Y.R.U. Marbleheads would have a sail area advantage over Naviga Marbleheads and perhaps vice-versa for “10 Raters” MI team 19/20 April. Witton Lakes. 1 Hove: Pp. Barker D. Daly 2 Bournville: H. Dovey M.
