The conclusions reached will be considered by Council at its first meeting in February (see below). All the Officers were re-elected. A vacancy for a Trustee was filled by Peter Maskell, the other Trustee being Ken Jones. Some concern was expressed over the low state of the Association’s funds compared with the previous year – accounted for by the cost of printing publications and stationery and various purchases (£464) including sweat shirts. (£495) With funds totalling only £470, it will be necessary to curtail further capital expenditure until funds are recovered from the sale of the various items held in stock.

GENERAL MEETING Will be held at the Novotel, Armbouts-Cappel, near Dunkirk, on Friday, 23rd July, 1982, at 8.00 p.m. PRESIDENT Byron Sansom (U.S.A.) wishes to retire after four years in office, during which he has played a prominent part in resolving the situation in America. He has been a good Ambassador for the Union and spent 3 weeks in South Africa last May as a guest of the South African Government for their Festival of Sport, integral of which Model Yachting was an part. Australia has nominated Neil Bennell as his successor – an ideal choice because he travels extensively and is keen to improve the overall status of the Union.

I have removed On many boats the jib and main sheets finish at bowsies on the boon. these and continued the jib and main sheets down the boom to eyes at the pivot points of each boom, and then led them back to opposite sides of a second D. Andrews Whirlwind winch pulley. The left hand stick of the transmitter still operates up and down for sheeting both jib and main out and in as standard. The second winch is connected to the sideways motion of the left hand stick. However, the stick itself is restricted in its left and right motion (elastic bands applied inside the Futaba transmitter) and only the left/right trimmer slide is used. This provides approx I revolution of the winch pulley with the trimmer slide under the left thumb. The advantages appear to be:- 1). Beating (a) During gusts the jib can be sheeted in a little more whilst at the same time the main is eased to prevent screwing up into the wind. (») During a lull the main can be sheeted in a little more than the jib to maintain pointing ability. 2). Reaching The jib can be sheeted in a little more than the main to prevent having either a flapping jib or an over-sheeted main. 3). @acking In very strong gusts when tacking is very difficult, the main can be sheeted in more and the jib eased to more the centre of effort back and kick the bows across the wind. 4). Rounding To speed up the rounding from a beat to a reach the jib can be sheeted in 5). Ease of Operation and the main eased so that the bows are pulled round. resting on the trimmer. All these adjustments come readily to hand with the left thumb 6). Minimal Battery Drain Beaause the jib sheet and main sheet are taken to opposite sides of the trimming pulley, they virtually balance one-another out and so this second winch can be operated from the existing 5 cell battery pack (for the main winch) with no noticeable reduction in battery life.

Your Editor has had a certain amount of contact with most of the boats and sailed four of them. As a result I thought it might be of interest to review the situation that has now been reached. THE BOATS No dimensions or weights are being published, but for those of you who may never have seen a 1/10 scale 12 metre I can offer you the comparison with the slightly more common A class. Generally speaking, slightly larger than an A class in hull dimensions, heavier at between 45-75 lbs., and weighing in they have substantially more sail area of around 2000 sq.ins. The designs by the model fraternity followed the trend of their A class boats and as a result ment look unusual by full-size criteria. penalty is different to the A class, tainly ventured into this area. edges of the fin as built, The sail and as first area penalty for taking a displacesailed, Roger Stollery’s boat cer- Dave Hollom’s boat had a trim-tab on both front and rear but used only the rear tab when I saw it sailing. boat is very much on the lines of his A class designs, and Chris Dick’s boat Dick Priest’s looks rather “Revolutionary”. Unfortunately the building programme suffered a number of setbacks. The most important error was to ask a man with little model experience to plank up six hulls to some very original designs. The resultant shells were not fair (to model standards) and in several cases the weight was excessive. Add on the weight of filler and you soon begin to see the problem! The second snag was that the idea of common fittings went out the window when some of the designers saw the bits and pieces offered, and as a result the rigging and fittings ended up all quite different. Lastly, the programme slowed up to such a degree that the Dick’s boat only took to the water in late August and took no part in any of the previous trials. THE SAILING The original idea was to conduct a series of carefully controlled trials with most if not all boats present at each venue. All results to be logged and the data to be used to assess any obvious strong point of each design. This commendable idea seems to have become lost completely with pairs of boats in various areas never seeing the others, many trials taking place in unsuitable wind conditions, and very little useful information being obtained. In fairness to the Project it should be said that no one could have forseen the break-in at Birkenhead that resulted in two boats being wrecked and of course the distances involved for amateur sailors who have other job and family commitments should not be underestimated. Nevertheless the idea was surely to show that Model Yachting could offer a serious test for prototype models and as far as I can see the end result has been anything but good for the model aspects. WHERE NOW? The last major outing for these boats was at Grafham Water in late October and once again luck was against the Project. Almost continously excessive winds meant that the sailing that took place was going to be impossible to relate to full-size twelves and a certain amount of damage also occurred. I understand however that the overall situation is that the tank-test model forerunner of Lionheart and the scale model SVERIGE have out-performed all the model twelve designs. Just before you all fall about laughing I should point out that the Swedish design has almost invariably been sailed by Andrew Hollom (possibly the most talented model R/C yachtsman in the U.K.) and that both this boat and the Lionheart designs were the subject of very lengthy tank testing. By contrast the model designers had a one-off stab at a rule they had not previously used, and at least two have substantially modified the underwater lines of their boats based on their first observations. The Victory Syndicate have have stated already started the construction of a conventional that a decision will be made regarding another boat which may be money and design investigation suggest it is worth it. does not appear to have made 12 metre and laid down if Unfortunately the model project the contribution that had been hoped. IMI CLASS RULE REVISION Following on from the earlier circular from the I.M.Y.R.U. Committee, a draft new rule has been circulated to all clubs for any amendments which must be sent in before lst July, 1982 to Chris Dicks. A postal vote for all countries in I.M.Y.R.U. by 31st December, 1982, will then allow a comprehensive vote line by line with a view to introduction of the revised and final set of rules by 31st March, 1983. CONCEPT INTENTION OF RULE: The Marblehead rule is not a “development” rule as is generally meant by this term i.e. “l0-rates” or ‘A’ class. It is a restricted rule whereby development is not prohibited, but is only allowed within the parameters of the rule, thereby largely maintaining the existing form of the class. Since the Marblehead is the most internationally popular class, the aim of the rule is to prevent any major change or breakthrough in the class with development taking place slowly along normally accepted lines. BASIS OF REVISION: To maintain the M Class as it known at present i.e. 50″ long monohull yachts with bermudan rig of 800 square inches. In addition, to more closely control any additional sail area without over complication of the measurement system. INTENT 1). 2). 3). 4). OF RULES: Basic Rule A clause to attempt to prevent any side stepping of the rules. Metric units to be included. Note degree of accuracy is not identical for both systems, but 1 mm. is all that can practically be achieved in metric measurements, whilst fractions of an inch more easily convert to 2 places of decimals. Inclusion of definition of overall length omitted from existing rule, and system of measurement where doubt may exist. Also the clarification and partial definition of bumpers. 5). 6). 7 8). As existing basically, except for inclustion of definition of movable keels. Basically as existing. Basically as existing except the sails restricted to a maximum of 2, of a basically triangular shape (bermudan rig) to avoid complication of measurement procedure. As existing except that permanently bent masts and spars are now allowed since they cause problems of definition, and cannot appreciably affect the actual sail area due to the introduction of sail width measurements. In addition, clause ‘g’ effectively bans luff spars as they are not generally considerable desirable. 9). Defines where sails shall be measured. 10). Basically as existing but additional clause clarifies situation for mast with luff groove. 11). As existing. 12). As existing. 13). Introduces sail width measurements in place of roach limitations to control unmeasured area. 14). As existing. 15). As existing. 16). As existing intention. 17). Sail setting restrictions mainly from M.Y.A. Sailing Rules but which are not included in I.M.Y.R.U. RC Rules. In addition clause (f) prohibits the “swing” rig, clause (g) is as current interpretation of rules, and clause (h) clarifies any possible misinterpretation. 18). As existing but with allowance for long numbers on narrow sails. 19). Clarification of existing rules. draft new rule INTERNATIONAL MODEL YACHT RACING UNION RATING RULES FOR INTERNATIONAL ‘M’ CLASS (MARBLEHEAD 50-800 CLASS) 1.

I am working with full-size and model yachting on National these problems, level in Sweden and have therefore spent some time thinking about and I can assure you that they are not restricted to model yachting. Before considering the yachting”. actual rules To me yachting is I think we should try to establish the “essence of to sail a boat round a course faster than the competitors without touching the marks or the other boats, and as there are more than one boat on the course we have to have rules that govern the right of way when there is a risk of collision between boats. Having considered this I think we should have a look at some different levels of racing, and I would like to quote Paul Elvstrom: “Firstly, There are those who like sailing and think it would be fun to sail their boats against others in a race; secondly, there are those who enjoy trying to make their boats go fast and to take the shortest way round the course, and yet only know the most who know the rules stick to formulated and would only thoroughly when describing the The beginner should first good way to of racing rules; absolutely thoroughly and try to interpret find this very well just elementary learn how approach the rules is to to like to delete rules everyone has to know. basic rules control his boat buy either it is all about: of himself, nut them correctly the word and learn In fact Elvstrom has playing inter-boat Ny “absolutely” and rules.

As the weather was a mild 20-27°C, with light morning winds rising to 10-15 knots in the afternoons, it was obviously a good test of boats over the 8 days. race reviews Whatever happened to race reports you may ask? Well, not every idea works and unfortunately the very low return of information, particularly from the South West, Midlands and North, meant that the picture would have been very unbalanced if I had published only those race reports I received. To compound this, several of the best reports received were to my certain knowledge going to be published in Model Boats magazine and would be duplicated in M.Y.N. Apart from the risk of being sued by John Cundell for copyright, this would in my opinion be a bit of a waste of space. Last but not least, the delay in submitting reports to me, coupled with the quarterly printing of M.Y.N. meant that the reports were more like history than current affairs by the time I got to them! I shall certainly try to re-activate the column in the next issue, possibly by a more general review of the level of competition in each area, so that newcomers have some idea where sailing occurs and what classes are most popular in particular clubs. To be successful I will need brief reports quickly from all areas, essentially of district and open events, but general comments from clubs seeking to publicize their sailing will be welcome.

I mean all internal structures, buy hulls ready made. not the hull, as I usually beg, The latest boat is an Ashanti, When I say borrow or as a last ‘inside’ resort made in epoxy resin and kevlar, with a hull weight of 94 ozs., including 3/16″ laminated inwales and ply transom. With a hull of this weight it is not possible to rely on the hull for very much support for shrouds, fin etc. although epoxy/kevlar construction is very strong and flexible as has been proved by the odd port tack boat!! Basically the shrouds, work which fin, mast and jib stay form a completely separate lightweight frame is independent of the hull, in fact this structure was made up separately from the hull complete with sails, winch etc. The deck centre section is cut from a” Gaboon marine ply which is very light, only about 3 ozs; bearing in mind the strains on this section this is quite acceptable. The rest of the deck is covered with Coverite fabric to alter things inside. My base shrink film. ‘Pigeon Toed Lemon’ now has Coverite is very easy to remove a Roger Stollery swing rig so the mast had to be moved forward approximately 14″ which entailed fixing a completely new mast step. Dead easy with no deck on. The Se ply centre section could be reduced quite a lot but in this case I wanted space across the boat, behind the fin mounting tube, for three winches so the receiver and battery box had to go behind the winches. Originally the deck forward of the mast had two Silent Gliss channels fixed to the deck. These two channels give a very easy method of adjusting the radial jib fitting, also the jib sheeting fairlead could be moved easily along the track accommodating the different rigs. These channels were later removed when the Stollery swing rig was fitted. want details of this rig get Roger’s plan, The fin construction is the cores of fins. shown in it this diagram, If you is all there in great detail. Balsa and Rhoacell have both been used for Rhoacell is nice to handle, easy to sand and does not absorb water. Although the present fin is covered with epoxy/kevlar a much quicker way of making a fin is to use 1/32″ or preferably 1/64″ tufnol sheet. Fin weight in epoxy/kevlar is approximately 5 ozs. and in 1/32″ tufnol 6 ozs. for a 45 sq.in. area fin. The radio installation, makes very helpful to the 0.0.D. it very easy to replace batteries, and other competitors in the smooth running of a race.

Some concern has been expressed in the U.S.A. that the adoption by I.M.Y.R.U. might result in rule changes that void the original idea and make obsolete the existing boats, One letter to the A.M.Y.A. even suggests that they might end up sailing against the 12 metre models being developed in the U.K. ~/10 scale and Europe. Since the EC12 model is about half the displacement of the scale twelves and has about one third the sail area this would obviously not be a practical proposition but the fact that there is concern shows at least that there are those anxious to try and avoid the class being “developed” into a hard racing class. At the A.M.Y.A. annual voting the rules have been amended, to tighten several inaccuracies in the wording of the rules but leaving the boats unaltered. The draught measurement in the rule book now agrees with the actual figure on the moulding! Mixing of sails of dif- ferent suits is banned, and the deck measurements remain as previously stated. In the U.K. several hulls have now been sold and I hope that owners will let me know when they have completed construction. Perhaps there will be enough interest to convene a meeting at a central venue later this year e.g. alongside the 6m Nationals at Witton Lake, Birmingham. The size of this lake would comfortably allow a vane race to continue with a small number of similar radio boats on the water and the good humour of the 6m event would be just the type of atmosphere to encourage the less competitively minded radio men. How about it Birmingham M.Y.C? Because of an oversight, the rules published in our issue 5 did not contain measurements for the working suit jib. These are, Luff 54″ max, 52.5″ min, Foot 19″ max, 17.5″ min, Leach 50.55″max, 49.05″ min. Leach roach 1″ max, Foot roach 1″ max. Battens: maximum of 2 allowed, in leach only, to divide it into three approximately equal segments. Maximum length 2″, Headboard, clew and tack gussets to be of the same material as the sail. The displacement limit has been deleted from the A.M.Y.A. 1982 rules, leaving the L.W.L. as between 43″ max, to 42″ minimum, to decide the actual displacement. for sale ECLIPSE R1OR.
