Almost since the easy access to radio control gear which brought about a revolution in the hobby, vastly increasing the potential for both control and useable water, we have listened to arguments about the correct title which should be given to this type of model. Widely understood as “Model Yachting”, there were many who felt that a change to “Radio Yachting” would help our public image, particularly with the manned boat fraternity who offer a major source of new entrants. The matter was decided for us by the decision of TYRU to insist on a change of name of our international governing body as a condition of entry into the prestigious Rules Book. Thus we understand that TYYRU-Model YRD will in future be known as TYRU-Radio YRD, and we have decided to follow suit. The next issue of this magazine will change its title, and reflect the changes in the way r/c yacht racing is percieved both in the modelling and fullsize world. Subscriptions. All new subscriptions run from issue number 44, and will include all the issues to date, 44/45/46 and the last of the year 47. The correct amount for the four issues is £10 Sterling or 20 US Dollars. Please pay in Sterling currency, or if not available in Dollar Bills. We have no facilities to change Dollar cheques which are heavily discounted by the banks to less than half their value. Cover Picture. David Coode writes in this issue about the 10 Rater class, and his active interest is shown in the cover photo of his latest boat, Airshaft, a Geof Draper design built in a simple form of balsa planking reinforced with epoxy resin and thin glass cloth. This apparently “kitchen table” approach has produced a really competitive yacht, first sen in the UK at our national championships. The boat is registered and measured in New Zealand, where David spends a lot of time when away from Guildford,Surrey, and is is showing appropriate sail markings. Round ind About. European One Metre Race Cancelled. We understand that the proposed first One Metre European championships scheduled for Cleveland next April has been cancelled. This information was given to us by MYA Vice Chairman Derek Priestley at the end of season A class race at Swanley, and is we understand due to the relative lack of potential entries from abroad. From a German contact two days later we were led to believe that entries could have been expected from Austria, Denmark, Germany and possibly Sweden, but we understand it was decided not to proceed with a relatively small entry. However the 1994 World Championship in France is very much ON, and European enthusiasts for the class can look forward to Poitiers as a chance to do battle at world level, against the strong New Zealand fleet as well. UK Marblehead Nats move. As a consequence of the above, Derek Priestley told us that the race scheduled for Birkenhead has now been reallocated to Cleveland. It will take place over the four day period, 9th/12th April, with racing to start on the FRIDAY AFTERNOON we hear. It may also be used as the UK round of the 1994 European Grand Prix Marblehead series. David Coode Yachts Nothing to do this winter? Build a boat!! Plans available include. One Metre Class.

As usual the venue of a world M class championships was used to hold as representative a General Assembly as possible, and that held in New York on September 14th 1992 had personal delegates from Argentina, Australia, Brazil, Finland, France, Germany, New Zealand, Norway, Portugal, South Africa, Sweden, United Kingdom and USA. Postal votes were also on hand from Belgium, Canada, and Japan, and others were sent from Austria, Italy, Switzerland, and Romania, but arrived too late to be counted. We have selected extracts of the most significant points discussed, as a full set of minutes has been sent to all National Authorities by the Secretary. Naviga Sailors Banned. This was the second General Assembly under the IYRU umbrella, and the minutes of the first were of course the first item on the agenda. This raised one issue of great significance to many mid-european countries, in that under an TYRU edict, anyone entering a regatta styled as a “World Championship” such as the recent one in Sopron run by Naviga, not sanctioned by [YRU-MYRD, would automatically be banned from taking part in any future [YYRU-MYRD event. Apparently this ban is “for life’, but we understand does not at present affect any events other than World Championships, although the Chairman has informed us verbally since the meeting that this may be extended at the January 93 Permanent Committee meeting. Composition of Permanent Committee. The Chairman Norman Hatfield invited anyone who felt that too many UK nationals were on the PC to comment before the new Officers were elected, and the general consensus was that there was ample representation on the Racing Rules and Technical Committee, and it was open to any National Authority to propose alternative nominations if they felt this was desirable. Permanent Committee. There were three nominations for the two nominated members, and Klaus Schroder from Germany lost out, but remains on the Racing Rules Committee. The resulting full new committee is as follows; Chairman Vice Chairman Gen Sec/Treasurer Chairman RRC Chairman TC Chairman O/P Publicity Officer Int Reg Officer Nominated Members N.D.Hatfield. T Klem. K.E.Roberts. H Ericsson. J Dejmo. D Coode. N Weall. J Cleave. A Somariva. G Vuillemin. Much of the meeting was taken up with talking about affiliation to the full size yachting authorities in members countries as demanded by the PC, and the problems in different countries, and the question of relating the fee payable to YYRU-MYRD to support its function to the number of votes the country might then have. The status quo of one vote per country was supported by a vote, in which the present six level fee structure was confirmed for 1993. PERMANENT COMMITTEE. Immediately after the general meeting, the new PC convened to discuss a number of items, including the composition of its two specialist committees. The Technical Committee is now; Chairman Jan Dejmo.[Sweden] Class Secretaries John Spencer [New Zealand] One Metre. Frank Russell [Australia] M Class. Graham Bantock [UK] 10 Rater. Bob Sterne [Canada] A Class. Rod Carr [USA] Members EC12M Standley Goodwin [USA] Gerhard Mentges [Germany] Phillippe Sol [France] Roger Stollery [UK] The Racing Rules Committee Claes Lundin of Sweden had been nominated as a possible member of this committee, but the membership was confirmed as unchanged, at least until the Jan93 PC meeting. Chairman Members’ Henry Ericsson Paul Chisholm [New Zealand] Guy Lordat [France] Klaus Schroder [Germany] J.D.Vincent[ USA] [Finland] John Cleave [UK] Dr B de Almeida [Portugal] Roger Stollery [UK] Nick Weall [UK] Regatta Calendar. Other matters discussed included the regatta Racing Calendar for the next few years, and the site for the first World One Metre Class championships was confirmed as Poitiers in France in 1994. VIDEO.

Nick Weall This was, in fact, the eighth “IMYRU” World Radio Controlled Marblehead Championship, but the first to be sanctioned by the International Yacht Racing Union – Model Yacht Racing Division. Held at Eisenhower Park, Long Island, New York under the race management of the 1992 World Sail Challenge Committee, the President of which was Dan November. Twenty three complete races were held allowing competitors to discard their worst three results, over the period starting Sunday 13th September until mid-day the following Saturday. First Impressions. The event got off to a very good start with an impressive opening ceremony. Near to the lake was a stage with a gentle slope facing it. The natural acoustics were first class enabling all of the competitors to be introduced first to the organising committee. Then each of the sixteen competing countries followed their flag bearing team captain up one side of the stage, walked across the stage and down the other side. Each team captain remained on stage until all sixteen team captains were sitting in a row. Norman Hatfield, President of the [YRU-MYRD made a short speech and after several other formalities and a splendid rendition of the American national anthem ,racing got under way. Light Winds all week. Weather conditions were excellent as regards the sun, but most unfortunate as far as the wind was concerned. During the entire week the wind strength never exceeded force three and usually was force one to two. Variable wind directions and marks laid in wind shadows demanded the very best of attention from the competing skippers as they lurched from wind shadow to wind shadow, fortunes often changing along the way dramatically. Those skippers who managed to rise to the challenge were without exception those same skippers who one would have expected to do well, what ever the conditions. They were wise enough to sail the middle of the course and to keep their yachts creeping forward no matter what. Their skills in rising to the occasion and reading the wind and its patterns upon the water, kept them to the front of the fleet. It was very interesting to note that local skills could not overcome the talents of the very best from the rest of the World, all of whom were suffering by various degrees to the changes to their normal body clock rhythms. A British Winner. It was entirely fitting that the eventual winner, five times National Champion of Britain should have finally mastered the rest of the World at a World Championships having been near to the top of several previous World Championships. Graham Bantock the well known sail maker, boat designer and general provider of yachts of high quality from his company Sails Etc of Kelvedon, Essex. Sailing his own designed Paradox which Graham had especially designed for the anticipated wind conditions in New York, he found the essential boat speed that had to some degree been eluding him through this season’s build up to the World’s. Graham had won his first UK National’s at Guildford in 1987, and as a result the following year he volunteered as the race officer for the Nationals at Gosport. The following four years he has managed to win the Nationals to make a record five wins. Despite strenuous efforts the first place in International competition has previously eluded Graham although he got second place at Berlin in 1988 in light air conditions, a joint IMYRU/Naviga RM World Championship. Graham’s Race Tactics. I was lucky enough to be able to interview Graham at the airport in New York before we started the long trek home. Graham’s memorable moments of the current championship included recollections of one or two blunders by the other top competitors that allowed him to gain one or two extra places in individual races. He realised very early in the series that the New Zealand boats of Robert Wattam and Geoff Smale were very fast and likely to prove to be the boats to beat. borrowed his girlfriend Kirsty’s boat “She Devil” and in Martin’s hands the boat had a lot of fun. Chris’s specially designed “Trucker” was not quite so successful, although in the designer’s very experienced hands he finally reached nineteenth place. Other Competitors. It was very encouraging to have sixteen countries competing in this Championships. It was obviously very expensive for most competitors to get to America and unfortunately some european countries had not been able to muster a team together. It was thus all the more encouraging to welcome back South Africa to the International scene. South Africa fielded a team of four competitors under team leader Geoff Mundy. Argentina, Australia Brazil, and Japan were other far flung nations that were well represented. Canada could not manage to find anyone prepared to make the effort which was a pity. The Team Trophy. The combined efforts of Graham Bantock, Peter Stollery and Mike Weston were sufficient to ensure that the team awardfor the highest three placed individuals from any one country competing in the World Championships went to Britain. Home Success. Jon Elmaleh managed a very creditable individual third place thus retaining America’s honour in this prestigious event. It has to be said that without Jon’s dreams and ambitions there would never have been a RM World Championships held in America. He was very well supported in the task of realising his dreams by Dan November, John and Madeline Tucker plus a whole army of very willing volunteer unpaid workers, providing all of the back up facilities required to run a top flight event. Much credit as always must be given to the long suffering protest committee chaired on this occasion by International Judge Mary Pera, who must be the best known authority on the racing rules in the World. She guided her committee with great patience and humour through the week. Their hardest task must have been after the final A fleet race. This was a very scrappy affair with plenty of incidents as the somewhat highly strung finalists engaged in the last battle of the event. The second, third and fourth positions were all hanging upon the results of last race protests. I did not envy for one second the heavy responsibilities placed upon our protest committee. The Best of the Rest. Christophe Boisnault of France could only manage sixth position with the same yacht as he won the Championship with in Fleetwood two years ago. National service in the French army has kept Christophe away from most races this year, thus his result is in fact a fine achievement. Claes Lundin from Sweden came in seventh position whilst Torvald Klem managed to maintain his usual high results with a creditable ninth. Robert Wattam has to be congratulated for his consistent sailing now over two World Championships. After second place at Fleetwood in 1990, Robert achieved the same excellent result again in New York. He looked in fact well in line on Thursday and Friday to take the Championship. Bad luck Robert, but well done all the same. Competitors from sixteen countries have now returned to their homelands, all enriched by the experience of competing against sixty-nine of the World’s top skippers and most of them looking forward to new battles in two years time in South Africa. Final Thoughts. A great big thank you to our hosts. To spend more than a year of your life organising such an event, just for the love of the sport is an enormous commitment and sixty nine competing yachtsmen and women are very much in the debt of a handful of dedicated officials who put in many weeks of work and a further army of helpers who rallied round over the week itself helping in a hundred different ways to make the event run as smooth as possible. A fair percentage of the sixty nine competitors tend to get rather highly strung and find all sorts of things to complain about in their search for the perfection that eludes them and whilst ideals ought to be pursued, the reality of International Competition is that it operates on a slightly lower plane. It provides many opportunities besides the honour and achievement of winning the event outright. The pleasure of meeting competitors from all over the World, making new friendships and renewing old ones, the exchange of opinions and ideas are all valuable facets of a World Championships. Graham recalled that there was very little opportunity for tactical sailing in the Championship, the wind strength was not very steady and the wind strength varied over the lake in a rather unpredictable way, so it was all very seat of the pants stuff, taking opportunities when they were available, you couldn’t really plan very far in advance. Even picking a place on the start line was not something to get too excited about, almost anywhere seemed to be O.K. because the wind varied so much in strength and direction etc, but in an irregular way so it wasn’t possible to pick good places. When asked if in that case Graham went for middle of the line starts Graham replied ” No, I just tried to get a start where I was not pinned down by other boats and I suppose that I succeeded most of the time.” The Winning Boat. I then asked Graham to explain what the new “Gizmo” does on his boat. Graham described it as the most useful thing that the boat has at present. The gizmo works on the rig controlled by radio control and it slackens the tension on the rigging whilst on a reach, the run and when not sheeted in very close-hauled. It seemed to be quite important, the boat had good speed whether it was blowing quite hard (A rig conditions) or when the wind went light, whereas some boats by the fact that they could not adjust their swing rigs during the race would often go quite well as the wind was light, but half way through the race if the wind picked up, then their jib would be too slack and they would not be able to point to well or if they had everything strapped for strong wind, the slot between the jib and the main was too tight for the lighter wind conditions. The Story of the Race. Graham had in fact made a brilliant start to the series sailing consistently well over the first two days. Over the same period John Cleave and Geoff Smale were also enjoying good results. Peter Stollery, Jon Elmaleh and Robert Wattam were also in the hunt. Tuesday was yet another day of light airs and delayed races coupled with an early finish and there was not much racing done on the day. Graham however if my memory serves me correctly started to slip away at this stage dropping down a fleet and allowing others to reach towards their dream of winning the Championship. Peter Stollery was sailing with great maturity and quite a lot of smart money was backing him to win. Jon Elmaleh was also very close whilst Janusz Walicki was slowly climbing back up the score board with his light weight Skapel. Janusz had managed to reduce the hull weight of his Skapel by around 500 grammes. He had encapsulated his batteries in the lead bulb and had thus prepared his very successful design for the light and fluky winds expected. As soon as the wind was force two or so the Skapel could hold its own. In the force one drifting conditions it struggled and it was only the skills of Janusz that kept his boat in the race. Wednesday was a lay day, when most competitors chose to visit New York city. The previous evening had been tremendously enjoyed by all competitors. A boat trip from Port Washington on Long Island out into the East River and down the east side of Manhatten and out to the Statue of Liberty was for most people the highlight of the week. It was a truly memorable experience and without doubt the best organised trip ever to date. Thursday again started off a little light with some slightly stronger breezes moving though in the early afternoon. Protests and some heat confusions delayed the racing somewhat. Robert Wattam, Peter Stollery and Jon Elmaleh were the favourites. John Cleave was slipping gracefully and slowly down the pecking order towards his final tenth position. As usual he had some cracking races and in fact in one race where due to some problem or another he started almost a clear lap behind, he practically overtook the entire fleet by the end of the race. British Boat Designs. The Stollery designed boat “Roar Edge” that John Cleave, Peter and Roger Stollery were all sailing in fact took the most A fleet first positions. Seven in all. This design in my opinion is the best British design at present , showing the widest range of performance ability from the very light to the force six wind strengths or so. Graham’s Paradox may in time prove to be its equal or superior, and Graham’s sailing experience is without doubt the best in our country so he may well have developed the Paradox to perform better than the Roar Edge over a wide range of winds, but it is yet to be seen. They are both, without doubt, great designs. Chris Dicks must have been very pleased to see his design “Slick” sail to eighth place under the guidance of Mike Weston, closely followed by Martin Roberts in eleventh place.

As you will have realised, this event was not exactly a “model” of organisation. I would like to put to [YRU-MYRD several points to avoid the next World Championships becoming a ‘lottery’ rather than a real race. What exactly are the criteria which TYYRU-MYRD demand when appointing to an organisation the next event? These, are obviously insufficient or not controlled properly, because the americans certainly did not meet the sort of standards required. Under the pretext of circulating the main events into different continents, an understandable motive, it is important that TYRUMYRD guarantee the sort of minimum standards which will ensure the event being respected. Have for example, South Africa or Australia the sort of facilities required? Will the lake be a sort of “duckpond”? What quality will the observers be, mute or blind? Will the Jury be fair and impartial? I will require some guarantees before I go to another such event. The Basic Standards required for a world championships are; 1.A course in clear air and open water. Berlin in 88 had the wind coming through trees of 25m height, Hertogenbosch in 87 had the windward mark placed in front of the cafe, fine for viewing but not for sailing, and Orbitello had so much seaweed you could make a good salad from the surface of the water!! And the USA had the layout of two courses, both in such a way that they each had little if any wind on half of them. 2.A ban on two or more courses, all races should be on the same basic course in any round. 3.Course marks of a minimum 30cm round, marked clearly with red and white diagonal stripes. 4.A race results list available within twenty minutes of the finish of each round. 5.Public display of all protest claims and their outcome. 6.The Jury is international, why not the observers and the Race Committee? Try to disqualify an American in the USA, or a British skipper in Great Britain! Bonne Chance!! 7. The organisation should be obliged to send a topographic map of the proposed site, complete with all trees, buildings and other obstacles to clear wind shown in full, before any future site is authorised by [YRU-MYRD. Christophe Boisnault. writing in RC Marine magazine report. 10 On Average the boats were lighter carrying less lead than at Fleetwood, A lot of boats had 7lb of lead and more sail flattening devices. Many were specials for NY average waterling beam would be around 6″ with someas narrow as 5″, bow flare and high bows were evident because of the narrower boats. The American boats with 7lb of lead had to go to B rigs when the wind got past 5 knots!!! Swing rigs were everywhere, except for the South Amreicans who admitted to me they were five years behind the times and were still useing RM1000 esigns with conventional rigs. Skalepl boats suffered badly in the conditions, the fact that Janusz Walicki got 5th is an indication of how good a skipper he is!! The boat and skipper combination that impressed me was Jon Elmaleh. he only boat I saw do penalty turns and still catch up. His local knowledge helped him in the early races. The [pits] venue in a hole tha same length and. width as our [NZ] lake with 60ft trees surrounding 3/4 of the lake. The 1/4 without trees has a steep grass bank and buildings. The wind fluctuated from 0-10knots in each race with 180deg shifts. Gaps between trees let squirts of air through at times. The “hole” place was worse than our pond on a westerly day with 10km over head. They also had a green slime, an algae type bloom which stuck to your boat. The Americans had a bucket of detergent and water to wipe down after each race. The only thing it didn’t have was weed. I di not fancy Bantock’ chances of catching some disease when they threw him in after the event. “YUK”. Robert Wattam writing in Radio Waves. ~ ‘ pARcouRS Rose PARCODRS VERT ARBRES (20 METRES yt), SDE Haut 11 The german team travelled with big expectations to the land of unlimited options, heading for a little pond in the proximity of New York. After our arrival at the race compound we becamea little pensive. What we saw was a tiny lake surrounded by many high trees and a lot of bushes in close proximity to the water. We had to realise also that there was a big building [in fact a theatre stage formed like a shell] near the start area. Though we had been prepared to face a little wind conditions we were not prepared to find a site that probably would be ideal for engine driven models. Today, back home and having sorted out my thoughts about this event I can state that I am very disappointed. My disappointment concerns first of all the organisation of this championships. I admit that the american organisers tried their very best, but there was an obvious lack of experience. To begin with, the choice of site already caused doubts, and the handling of single races was frustrating. The existing scoreboard was not used to the benefit of the competitors. The ACTUAL results, promotions and relegations and the finishing order were not shown at any time. So it happened twice at least that there were no explanations why the last finishers of ‘A” fleet were not relegated but started again in the following “A” fleet. Should this be blamed as computer error or was it the result of a jury decision not announced to the competitors? There were also plenty of claims about the performance of the Observers, as contacts were seldom penalised. Nevertheless there were lots of Protests. More than 70 requests for redress were filed, in one case for a not proven radio interference. According to british publications these kind of requests had been influencing the order of the first three places. As the regatta schedule was often blocked by protest hearings for a long time, the competitors gathered round for discussions, feeling bored of the reluctant handling and had to ask themselves whether their efforts concerning time and a lot of money of each individual were in a reasonable relation to IYRU-MYRD recognised world championships. Remember 1987 Gothenburg Sweden with its huge flop, as the first day no one of the organisers showed up. The second day of the event was wasted with building up a launch facility. At Orbetello/Italy the daily chaos became routine, and also there were preotest hearings of unbearable length. In contrary to this, the first world championships organized in cooperation of both IMYRU and Naviga at Berlin, Germany was an exception. To provide the best possibilities for start in free water long pontoons were anchored and a well performing computer crew transmitted the results almost in “real time”, [as they did at Fleetwood 86 and 90] for presentation at the race board. Of course there were also protests, but the bigger number of those protests had been decided without causing any delay, by the Jury Chairman Hans Kukula, already at the water. I think it would be worth taking into consideration, that the competent IYRU representatives should visit a “Wolfgangsee raceweek”. Over there they would get an impression how such a big event with 70 participants is handled in an extraordinary performance by three persons of the Kukula family only. Maybe it would help already if some greyhaired men would enjoy their pensions while living in retirement. Janusz Walicki.

John Lewis’ own boat, Tempest, sailed by Mike Harris at the recent Swanley RA 12 New Australian 10 Rater design. There has not been much new in the way of design in this class for some time, but in Western Australia over the last two years a new design, codenamed R10-2, has been developed by a small team headed by Alan Robinson. Intended to show how the application of modern bigboat design and construction techniques can be applied with the best results in model size, the basic lines were developed on a fully featured yacht CAD system. This allowed access to relevant data for; Stability and sail carrying power. Overall resistance. Velocity prediction. Graphic Imaging. Shape generation by machine. This process largely eliminates prototype as form parameters are adjusted to optimise performance long before construction commences. Final form. The hull shape incorporates topside flare for a large reserve of stability. Buoyancy and rocker are well aft to delay separation. The hull wetted surface is minimised for this beam and displacement. Good hull balance allows overdriving without loss of control. Construction. Low weight, high test materials are used throughout the hull and appendages to fully maximise the boats potential and maintain a high power to weight ratio. Material used include kevlar/epoxy/carbon fibre hull layup, epoxy/carbon fibre fin and rudder, kevlar/carbon fibre/nomex sandwich deck. Performance. The R10-2 design has satisfied original parameters and predictions in its on the water performance to date. The design has performed to expectations through a wide range of conditions and continues to improve through minor tweaking and optimising of sail design. More Info?

The Ten Rater class will see a further world championships, the seventh of the series, at a venue in South Australia. The organisers have realised that it will be necessary to convince many potential competitors that this will be a good place for a family holiday, and thus justify the cost of travel, and have sent out a dossier of information on the region. Lake Bonney has been the site of many gliding, power and ski boat world championships, a number of “people” type yachting events, and many years ago Sir Donald Campbell used the lake as a site for some of his waterspeed record attempts. Barmera itself is on the south end of a backwater lake formed by the Murray river, and this is Lake Bonney. It is at least 10km long and 6km wide so its will be an openwater type wave formation, and presumably good wind conditions. Whilst this may establish its credentials as a good venue for radio yacht racing, family members may be more interested in the fact that Lake Bonney is situated in one of Australia’s major tourist destinations, an area called Riverland where the Murray river runs though many towns and makes the area a centre for wine, grape, citrus and stone fruit crops growing. Visitors can of course tour the vineyards and sample the local products!!! Its not just foreign visitors who grow to like the spot, and last year’s State Title M class saw many families visit, and enjoy the scenery, craft shops and the country towns of the region.

In addition to a number of Six Metre class designs he has also done a range of A class ones, some for individual skippers who wish to keep them for themselves. On the other hand there are a selection which can be obtained direct from John Lewis for a modest sum, and these include: Catswhisker. A 1987 Design for which David Trippe has the prototype, of dimensions; LWL; 50.5″ Disp; 37.51b LOA; 76.5″ SA; 1540 Sq In. Price; £15 post free. Catswhisker Mk2. As above but with a prognathous fin, now allowed under the revised class rules. Price; £15 post free. Juno. A brand new, and as yet unproven yacht, for which the prototype is now being built; and the first of the new CAD based Lewis designs. LWL; 48″ Disp; 30lbs LOA; 63.35″ Price; SA; 1470 sq in. £20 post free. If you want a bespoke design using your preferred LWL/SA etc, you will have to pay around £75, and of course they have to take their place in the queue, so the above design offer a quick way to get an excellent design for home building. All enquiries to; John Lewis, the Barn, 4 Monument Lane, Rednal, Birmingham, B45 9QQ. New Bantock “A” Class Design. Graham Bantock has sent out a circular in October 92 asking for response to a possible new radio A class yacht, essentially optimised for UK conditions, but with an eye to potential use at the 1993 World Champs in Denmark. The venue in Denmark is reported to have windspeeds of between 0 and 10 metres per second, and this makes it quite similar to average UK conditions. In an attempt to get a set of parameters in which a reasonable number of potential customers might find common ground he is asking for a number of bits of information, including displacement and sail area range.

Some months ago we were sent a sample of a new through deck pulley manufactured by the world renowned Pekabe company. This is a great improvement on the earlier single pulley version, and close examination shows how the change allows it to be used in either forward facing or stern facing mode. The overdeck flange has been widened to give greater watertightness, and there are alternative mouldings to give flush fitting to either flat or rounded decks. The line outlet above deck has been given the same height as a deck mounted pulley block so that a sheet line may have the least amount of friction in this situation. Both pulley blocks are fitted with ballbearings. Weight is only 4.6grams complete with mounting screws. Pekabe has a number of outlets worldwide, and you should have no trouble getting this item from them. If you do, write to Pekabe, Postfach 27, D 6301 Fernwald, Germany for the name of your nearest stockist. Mac Fit. Not so well known as some other suppliers, Bernie McNulty has gradually developed a wide range of fittings, including a number of vintage ones suitable for restoration projects, lead keel weights for popular classes, sails and timber cut to suit yacht construction. Last year Bernie produced a neat catalogue, and this laid out the items clearly, giving a lot more detail and including prices and postage costs. Bernie McNulty can be found at 1 Lakeside Court, New Brighton, Wirral, L45 1NS, telephone number 051-639-7106. Swan Model Yachts. New Marblehead designs for 1993 include an updated Slicker, modified from the original Chris Dicks’ Slick with increased rocker and bow flare, and a production version of Roar Edge, Roger Stollery’s 1992 New York special which has recieved rave notices for its performance in a variety of conditions. A new One Metre class yacht, Wafer, is also in the offing, and of course the now well known Comick remains in production, Swan Model Yachts are to be found at The Bungalow, New Barn Park, Swanley, Kent, BR8 7PW, telephone number 0322 666363. 33 Traplet Yacht Plans.
