The float chamber is of lurge capacity, which overcomes the common fault of engine starvation. The petrol passes through to the variable main jet, whichis of the submerged type, and thence through the diffuser jet, which is also needle controlled, thus simplifying tuning up. This carburettor also gives you perfect slow running and instant acceleration. | First-class din. for Decks, and any thickness up to 24ins. wide. Verney Road, Rotherhithe New Road, 6d., post free.

No. 7. THE ~ a M.Y.A. are Lagoon Times, which is the private journal of the Hove and Brighton Model Yacht Club, in its August issue gives an epitome of the Sailing Rules of the Model Yachting Association for the guidance ot its members. Referring to Rule 10, it quotes: “Handling yachts: Whenever a yacht comes to shore she must either (a) be Tacked, or (b) Retrimmed—For (a) Windward Boards yachts shall be turned fairly about by the skipper taking a firm stand, and (1) turning the yacht off by placing the pole against the lee bow, and (2) he may also steady her round with the pole against the lee side of the counter as she sails out. In any case, her headsail must fairly and definitely fill on the off-shore tack before she leaves her skipper’s control. Failure to do this shall entail disqualification for the board.” ‘This rule seems clearly The writer adds: expressed, but it was noticed that it was not always obeyed at this year’s Eastbourne Silver Cutter Race. Several boats nearly fetched the winning line on the long tacks to windward and instead of being turned definitely away with jib full on the off-shore tack, were edged along shore, after retrim on the same (on-shore) tack without swinging over jib or guying; this gave them, in the light wind, a great advantage over those of their competitors who strictly obeyed the rule and turned off-shore on the guy which did not always act in the calm. The officer of the day did not at once definitely uphold the rule, and several disputes occurred. If 3 points are being awarded for a weather board our view is SAILING RULES. that the rule should invariably apply and a yacht be turned (tacked) off-shore, usually of course on the guy, and if the wind has veered so that the course has become almost or quite a reach, the turn off-shore on the opposite tack should still apply if 3 points for a windward board are still being awarded. The Editor of THE MODEL YACHTSMAN should pronounce upon this subject.” In answer to this. the rule gives the skipper two definite options: he may elect to tack, in which case he must turn the boat definitely round and fill his jib, or he may elect to retrim, in which case he can go off as he likes. The competitors who thought that they could pinch their boats a little closer to the wind and keep along the shore were quite entitled to do so, so long as they retrimmed fairly each time that the boat came back. It is a very difficult matter to frame rules that will definitely cover every situation, but the spirit of this rule is very obvious. When by retrimming a yacht can fairly sail off the lee-shore a retrim is not only legal, but perfectly fair. When she cannot fairly sail off by closer hauling the sheets, obviously she must be tacked. As regards scoring, it is the officer of the day’s province to decide whether this is 2 and 2 or 3 and 2. On many days the officer of the day might fix the scoring at 3 and 2, and the majority of competitors have to make several legs, whilst a really closewinded yacht sailed through in one leg. 132 The THE MODEL Model ENGINEER WE must confess that we were disappointed in this Exhibition as in spite of the fact that there were a number of brilliant exhibits in the Competition Section, generally speaking the quality of work did not quite reach the exceptionally high standard that we have been taught to expect, and it also October 1931 Yachtsman. EXHIBITION. A. Fleming (Southsea), Ltd. Amongst these was a charming model of the Clipper Ship, “ Loch Mordart,”’ a boxwood model of a two-decker battleship that was very beautiful and two nice specimens of bone prisoner-of-war ships. The latter were the **Centaur”’ and the ‘ Pacificator,” both of which than in previous years, especially as regards marine had been beautifully restored (and here we hazard a guess) probably by Mr. Beauforth, whose work is models with which we are solely concerned. almost unmistakable. In the Competition Section we noticed a particularly beautiful example of miniature work in a miniature double cylinder (}” by 4”) high-speed marine engine entered by Mr. A. P. Izard. This ‘** Mermaid,” lent by Mr. Will E. L. Day. A beautiful model of H.M.S. ‘* Renown’ was also exhibited. This is the work of Mr. H. V. Davis, and gained him seemed to us that the number of exhibits was less little engine was steamed at 40 lbs. pressure for 13 hours ahead and then 13 hours astern. It was also tested up to 75 lbs. working pressure. This exhibit was awarded the Exhibition Bronze Medal, which it richly deserved. a Bronze Medal at the 1930 Exhibition. There was also a fine sailing model of the “‘ Cutty Sark * by Mr. Roland Oliver. The hull of this craft was beautifully finished. but her rigging was modified to suit working conditions. In the Sailing Ship Model section, the Ship Models Cup was taken by a very fine little waterline model of the ship “Mary Penhale *” of London (1875). We do not appear to remember having heard of this vessel, but from her model she was a very pretty craft. The builder of this model was Mr. J. D. Attwood, who must be congratulated on a fine piece of work. A seale model of a Merchant Ship of the fifteenth century by Mr. C. Newton was noticeable for meticulous accuracy of detail. There was also a nice model, rather of the decorative ship order, of the “‘ Anne Royal” (1625). A model or a 50-gun ship (1730-1740) was obviously oversparred. There was a nice model of the “Cutty Sark,” and Mr. B. Lavis was responsible for a couple of miniature scenic models. We also noticed “Jeanne,” Mr. A. W. B. Prowse’s beautiful Thames Barge Model, which was illustrated in these pages some time ago. Amongst the steamers and power craft exhibited, there was a nice model of the “* City of Canterbury,” spoiled by poor rigging, which was done in the same size cord from funnel guys to flag halliards. Mr. C. S. Chambers was responsible for an excellent model of the Barnett Motor Lifeboat, made from plans published in THE MODEL YACHTSMAN. Two interesting little models of steamers made from cardboard by Mr. M. G. Stevens, showed what can be done with this unpromising material. In the Junior Section there Model by L. W. Paine, which could have been improved by we published some time ago in There was a fine working model paddle steamer, was a Sailing Barge was quite good, but consulting the plans this magazine, On the Sample Display Stands, Captain C. H. T. Alston showed a model rowing dinghy one metre long and a model steam launch. ‘The hulls of these were excellent examples of double-skin diagonal planking. Amongst the Loan Exhib-ts was a notable little collection of historic ship models lent by Messrs. Probably the most wonderful model in the Exhibition was a miniature model speed launch. The dimensions of this boat were: L.O.A., 82 ins. Her engine was 7” x i” slide valve. She runs on solid methylated fuel, running three minutes at a filling, and she has been timed to steam 43 m.p.h. The maker of this little wonder is Mr. G. E. Southey, who must be congratulated on a remarkable feat of miniature modelling. Amongst the Club and Association stands, the ‘Model Yachting Association was conspicuous. The exhibits consisted of the A-class ‘* Hermione” (T. H. Willey), winner of the British Empire and World Championships, a new 10-rater by Mr. Osborne (M.Y.S.A., Kensington), from the designs of Mr. A. W. Littlejohn, another 10-rater from the South London Club from Mr. A. W. Littlejohn’s “Flying Spray” design, a new 10-rater by Mr. O. Steinberger, and an example of THE MODEL YACHTSMAN “Star Junior” 36-inch Sharpie, built by Mr. A. J. Child. Mr. Steinberger’s 10-rater is a most interesting boat as she entirely departs from standard 10-rater practice. Her waterline is far longer than normal boats of the class, and she has a very high narrow sail-plan. Her displacement is also greater than usual. Altogether she is a very pretty boat and a type that we have long advocated as being what is now required under the rule in view of recent developments in sail design. She has been pretty successful in the short time that has elapsed since her launch, and we anticipate a very successful career for her. The Ilford Model Power Boat Club was represented by several boats built and owned by members. Included amongst these was an interesting Hydroplane hull in frame in course of construction by Mr. T. Jones. The South London Model Power Boat Club had an excellent display of craft, including Mr. Ford’s Hydroplane which has recently done 27 m.p.h. October 1931 The Model Yachtsman. 135 H.M.S. ‘“‘KENT’’ OFF CHATHAM. In connection with Navy Week this,summer, two large models—we believe one-fifth or one sixth of full-size—were built from the lines of H.M.S. “Victory.” The photo shows 99 one of these models which was constructed in Chatham Dockyard. THE TOPIARY SHIP. In our August number we showed a picture of this group of trees clipped into the shape of a threemasted ship with fighting tops. A small prize was offered to the first “ spotter ”’ of its location. Post-cards were received the day after publication, and we have decided to divide the prize. Postal Orders have accordingly been despatched to the two winners. As the “ship” is at Cadnam on the edge of the New Forest, it was to be expected that the winners should come from the South Coast. No doubt our Northern friends will think this not quite fair, but we hope to have another similar ‘‘ contest’ which will give the Northerners a better chance. ‘(egy abnd uo fay ag) WSDLHOFA TACOW AHL 10} uavrp Ayperoedg a, (2) as) rm = & > 90 Sle T?P9N P41 > 2 le) | TTI 7 ow aaa 4 TROT ASE . \ “UBUIS}4IV FEI > [jo 7 1938 REG 1°4070@) ‘oUNDW “M “9D 4q NY wn = > Z s) a 2) = ESS 98 0 \ 9) o¢ we October 1931 135 Yachtsman. ysadS1vo0lr.]g7,uaep1y aaesunry kvj usr0uee,dJoay0SsepAv[lJ9YS up9usunearp1sqree0iyalyr4sy[ySyair}iJgnsels”p]npuoravdvdjyyevaSsOeu[lgy The Model e104] [ehoy Sy] 901 801 60!
