Y. C. and the Montclair M. Y. C., have pledged one hun- dred dollars each to help carry the financial part of the venture, and others are pending. As to the rule under which boats are to be built, a proposed rule is given elsewhere in this issue, which as a test rule appears satisfactory. It is believed progress is being made towards a fixed understand- ing and cooperation between the two associations and when con- cluded this may well brmg about a big event in each season to come. Those clubs and members who have been keeping their weather eye on the larger aspect of model yacht racing, and have noted the response and attention accorded the first International Race here last June, see in this attempt to get on a common basis a real step forward in the model yachting game. It is up to all those interested to decide whether or not the sport is to be broadened and assume the dignity this sterling pastime deserves. | ) t 2 ; ion J Site: — a / | an TT 3| / | + y * oi / Vil] A\t/ | ani CH 7 || 4 a s 3% so i: :| | 2 : “T] | ee “ss 18 g. 3° / | a} 89 a an | i –9 “I “T il Ee a e A , HL | | | \\\ \ \} \ \\ }\ + ni EER ie : ‘ we &l2 Sq 28 ea = i\ } \ \3\ \ | \ | \ | | | \ \\\ | \ V\I\ 1 ia ‘ie ii aot \\ ‘ | | eee 4~—- = f The Central Park M.

American model yachtsmen have never been strongly in favor of the theory that a model yacht should be an exact scale reproduction of its larger sister, being concerned largely h in getting the utmost speed on a given waterline length. The same desire accounts largely for the difference in design between a 6-meter yacht and a ninety-footer. To illustrate the type of yacht developed by the new conditions we have asked Mr. J. O. Bergh to design a :nodel to the Yachting Monthly Cup conditions, which design is shown in this issue. It is in’ teresting to compare this rules. The appendage of Owisquat (as shown in the lines in YAcHTING for October) is larger than that of the new boat owing to the much greater draft, and on equal rating it is possible to get more displacement and power in the new hull, which makes up in a measure for the loss in power due to the higher location of the ballast, and she will probably heel no further than the older boat under given wind pressure. The sail area is smaller than Owisquat’s and she will probably stand up to it better and we would expect her to be faster in heavy weather. On the other hand the older boat, because af her greater spread, will do better in light airs such as are usually had ments of the new boat built under this new British rule: LeOe 6505″ L.WeLe—46.0″ in waters during the racing season. our There seems to be, after all, an analogy between the models and the full size craft, for here the English Rule develops, in models, a heavy weather boat much as English designers usually provide in the big fellows. The American contention is that the model needs excessive draft because they are close to the surface in broken water, and we now have some incentive to try out the two systems. It will be interesting to see boats built to the English Rule in competition with our M. Y. R. A. Class B yachts.

A. Rules and sailed in the International Eliminations last June. The two boats are practically the same L. W. L. and displacement, and show well the results obtained under the two 31 wvD Hull measured Universal Rule (American) Sails measured International Rule (British) Model Power-Boat Classifications The model power-boat men have not had a very successful season this last year, possibly because of the overwhelming interest in the sailing yachts, due to the international race, possibly because they are pretty well scattered. The Model Yacht Racing Association has not yet formulated rules for classification or racing though there are hopes that they will reach the power boats this winter. quests Having received many re- for information on power boat classification and racing rules, we have been looking into the mat- ter and find little legislation in this line among the clubs. The Central Park Model Yacht Club has been racing power boats for some years, at first with no re- strictions except as to length, then with a weight and piston displacement class. With this experience, they began to develop ideas and last March we printed the tentative suggections of Vice Commodore Harry Johnson, who is one of the most enthusiastic model power-boat men. Mr. Johnson has carried his thoughts still further and _ has evolved what promises to be a very satisfactory set of rules for classification and racing, which we offer here for the use of the many enthusiasts who have been asking for something of this sort. Model power boats are to be rec- ognized only when filling the re- quirements of one of the following four classes: or guided by line or trolley. To avoid accidents the boats will be run one at atime. This is not spectacular but is conducive to the best results and most speed. Starts to be made from behind the line and times taken at crossing the start and finish lines. Should the model stop for any reason except that of mechanical failure it shall be entitled to a restart—three being allowed each boat. Should it turn in and touch the bank (or go wide of the course if in open water) unless turned by drift or flotsam on the course, to be disqualified. If turned by drift or flotsam, the boat will be allowed a restart. This method does away with the advantage to be gained by the owner with the greatest number of willing friends to line the course and put the model back on the course, and permits the best boat to have a chance of winning. It gives an opportunity of rating and timing every boat, so that the owner knows just what she is doing and can form opinions as to changes to be made. The tether should be compulsory for all flash steam plants which are capable of really great speed. A straightaway can, of course, be ar- ranged at some expense and as the boats are much faster over a straightaway than on a tether, this would give an advantage to mere money in the comparisons of speeds. Mr. Johnson also suggests that record of all races be turned into the M. Y. R. A. so that the best boat in her class, wherever she may be, can be designated. If any model power-boat men have ideas on this subject we will be glad to hear from them and hope that we can get this side of the game definitely settled so that the builders can go ahead, certain of having recognized racing for their craft. /div>
