With this number the good ship ““ THE MODEL So far the Correspondence that has reached the paper has been entirely confined to expressions of pleasure at the launching of our venture, and messages of good wishes for our success. These have come from as far away as Canada, Egypt, Germany and Norway amongst many other places. We have many good friends, and all we want is more and more subscribers, and then we will hope to give our readers a bigger and better Magazine than we present to-day. We have many good and novel features in view for future numbers. YACHTSMAN ” starts her maiden voyage, and we hope all model yachtsmen will speed her on her way. This Magazine is being run by model yachtsmen for model yachtsmen in the interest of the sport, and we want your help and support to make it a success. Obviously a great sport like ours requires an organ of its own, but even a modest little journal like THE MODEL YACHTSMAN costs an appreciable sum to produce. It is not sufficient to merely read the paper at your Club, and though we start with quite a nice number of annual subscribers, we want more. So if you like the Magazine, recommend it to your friends and get them to subscribe also. We trust that our Magazine may bring pleasure to all our readers, and then indeed shall we feel recompensed for our labours on their behalf. THE EDITOR. It is our intention as far as possible to exclude model yachting politics from all parts of the paper with the exception of the Correspondence Columns. Further, the paper will stand for a fair field and no favour to anybody. Our Cover Design. For the opinions published in the Correspondence Columns of the paper we take no responsibility about various topics, and no doubt our columns will be the lists for many a wordy argument, and we The charming little picture which adorns our cover is the work of Miss Feltwell, and represents Mr. Scott Freeman’s celebrated model ‘‘ Crusader.”’ Miss Feltwell was also responsible for the spirited original poster which was shown with the display of prizes at Gosport last summer. This talented young lady is the daughter of Mr. J. G. Feltwell, the hard-working and popular Hon. Secretary of the Y.M. 6-m. M.O.A.

Within reason these columns are open to all readers, and we trust that they will make suitable use of them. Naturally, if it is desired to use a nom de plume, the writer’s name and address must also be sent, but this is entirely confidential to the Editor alone.

Secretary, I.M.Y.R.A. Two fresh countries, Belgium (Antwerp M.Y.C.) and Norway (Norsk Modelseilforening), have applied for admission to the I.M.Y.R.A. In Holland, the Model Yacht Sailing Section of the Royal Dutch “I ON eg Oe teeee ee Tea Py Sa a WEES So ba ny ea > Aquatic Sports Association are considering the question of applying for admission also. In Sweden, the difficulty appears to lie in the constitution of a National Authority. Formal application has been made for the inclusion of Model Yachting in the Olympic Games. It is too late for this year, but we hope that next year we may have the pleasure of seeing our sport take its proper place in the Olympic Games Programme. The Constitution and Sailing Rules, and A-class Rating Rule are now printed, and can be obtained through the various National Authorities. The new form of A-class Rating Certificate is also available. So far only the A-class has been adopted for international racing, and as there is a rumour flying about that the B-class will be a 6-metres class on a scale of 1} inches to the foot, I have been asked to give an authoritative pronouncement as to whether there are any grounds for this. When the International Committee of the I.M.Y.R.A. was in session at Gosport last summer, the question of a smaller class was raised. Some of the national representatives were very strongly in favour of a simple rule class, and both our 10-rater and the Scharenkreuzer classes were mentioned. It was considered advisable, however, to ascertain what was happening about the I.Y.R.U. formula before attempting to come to any decision whatsoever. At present the entire position is absolutely open, and there is no real indication as to what will be favoured. I must, however, point out that the M.Y.A., representing Great Britain and the British Empire, has no more voting power than the United States or any other of the nations composing the Association, and the matter will be decided in due course by a majority vote of the national representatives. Model Yacht Racing Asscciation News. By C. The new races that are being staged this year are exciting great interest. The first of these is the Bradford Cup (A-class) on Yeadon Dam at Easter. The Cup and replica, the latter to be won outright, have very kindly been presented by Major Butler of the Bradford M.Y.C. The second prize is being provided by the M.Y.A., the third has been presented by the Y.M. 6—m. M.O.A., and the fourth by Mr. Averay Jones, the popular Commodore of the Bristol M.Y.C. Entries have been received from Scotland, Cardiff, Derby, Birmingham, three London clubs, Liverpool and the Home Club. The Officer of the Day will be Mr. Cuthbert Paine of International fame, and Capt. F. W. Lazell, Asst. O.0.D. Competitors are reminded that they must report their arrival at the Talbot Hotel, at or before 6 p.m., on April 6. The London League Regatta (10-raters), which is being held under the auspices of the M.Y.A. at Forest Gate, on June 23rd, promises to be a very well patronised event. The prizes for this race will be of the value of £3 3s. Od., £2 2s. Od., and £1 Is. Od. Mr. H. B. Tucker and Mr. A. J. Hugo, Chairman and Vice-Chairman of the M.Y.A., will act as O.0.D. and Asst. 0.0.D. They will also have the assistance of N. Force, Hon. Secretary, M.Y.A. Capt. Lazell. Our friend, the ‘‘ Cap,” has been forbidden to sail his ‘little yacht’ this year by doctor’s orders, but he will be to the fore in the official work of the season’s racing. What we lose in one way, we gain in another. Another good race should be the Eastbourne Cup for the A-class, which is to take place on the new lake at Eastbourne at Whitsun. A race is also being held for 18-footers at Belfast Waterworks Lake, which should be of great benefit to the Irish Clubs. We understand that the Ulster, the Ormeau and the Victoria are all likely to be represented. . Owing to the extended Racing Programme, the M.Y.A. has need of more Individual Members. It is also hoped that those clubs that have not yet joined the M.Y.A. will do so, and thus help on the good work now being accomplished by the Association. I shall be very glad to furnish all particulars as to joining the M.Y.A. to any clubs or individual model yachtsmen who wish to join. The Gosport Fund is now opened, and contributions sent to Mr. H. C. Whetstone, Hon. Treasurer, M.Y.A., 86, Park Road, Hendon, N.W., will be acknowledged in due course in these columns. Gosport Regatta, 1928. As there are two Scotch A-class boats sailing at Bradford Cup Races this Easter, we hope that our friends from the North will be well represented at Gosport. An interesting entry for the British Championship is a boat from the Durham M.Y.C., South Africa. these races will be the Mirror Lake at Washington. This is a fine artificially constructed lake, and is part of the Lincoln Memorial. The lake is so The foreign entries for the International Races are France, Germany, U.S.A. and Norway. We understand that Germany, France and the States will each hold Selection Races to determine their representative. In the case of the States, the venue for craft. Another German boat is from the board of Constructeur Tiller, who is probably the best known designer of model yachts in Germany. We may situated that it mirrors the monument itself. interesting entrant for the German race will be the model designed by Herr Rasmussen, the world-famous German designer of full-size racing An therefore expect some from this quarter. pretty warm competition April 1928 The Model Yachtsman. 3 The Measurement of International A-Class Models. By W. H. Bauer, © Official Measurer to M.Y.A. International Meetings, M.Y.S.A. (Round Pond), Y.M. 6-m. M.O.A., etc. In this article Mr. Bauer gives full instructions for measurement and working out Certificates for this popular class. He has also prepared a photo print of the apparatus required. This should be in the possession of every Club which caters for this class, and can be obtained from Mr. Bauer for 1/9, post free (for address see Advertisement Columns). We publish sketch of this in our May issue, page. 27. The increasing popularity of this class and its elevation to international status, coupled with the necessity of producing Rating Certificates at all first-class races, renders it imperative that all Club Measurers should be au fait with the correct methods of measurement. she is stopped by the bar.
