Nedwidek, N.A. q AST month, we completed the hull proper of this speedy Marble- head Class sailing yacht. In this ticle we will make the keel, and her, ready for the water. Since last issue appeared, a number of arrig the be- ginners have written in to ask what the numbers, “50-800” mean. These figures refer to the size of the yacht. The first figure refers to the fact that it is 50” in overall length, while “500” indicates the number of square inches of sail area. This class of yacht was introduced a few years ago, and beCause it represented such a sound, workable size, it has taken the country by storm. It is today the most popular class. Big enough to give a real thrill in sailing and building, it is, nevertheless, not too large to transport. This is also known as the Marblehead class, after the Massachusetts town where it was originated. No matter what type of hull con- struction you used, the keel is made on the bread-and-butter pattern. If solid lifts were cut out, glued to- gether, and shaped, there would be a strong possibility that warpage might destroy the shape of the keel after the yacht had been in use. This is overcome by making each keel lift in two halves, carefully planed and glued together. The halves are cut from 34” stock, and the section lines on the sheer plan are used for the outline. Drill the bolt holes for fas¢- weight of the fittings, and a 1% pound weight at station 4 to take the place of the rigging. When placed in the water with these loads, the hull should float to its designed waterline, as indicated in last month’s drawing. If she is too heavy, shave some metal off the keel. If too light, you can add weight in the form of strips of lead screwed inside the hull just over the keel. If this amounts -to much, it will be better to make a new, larger, keel make a lead casting for you. Put short dowels in the pattern to give the location of the keel-bolt holes. When you finish off the casting with a coarse file, use brass bolts to hold it in place, and set white lead around the bolts. To mount the rudder, drill a 4” hole in the backbone and king plank of the hull, and set the rudder port tube in with white lead. The rudder post is of 5/32” brass rod in two pieces as shown. ‘Turn down one end of the lower piece of 3/32” diameter for the heel bearing. If you do not have a lathe for doing this job properly, you can drill a hole in the end of this piece, and solder a short piece of rod into the heel bearing, to fit this hole, instead of the arrangement shown in the drawing. The heel bearing is filed from solid brass, pattern, and have a new lead keel cast, as it is far better to have the weight down here than up nearer the waterline. Next we start with the mast. This is hollow, to combine the greatest possible strength with light weight. At first thought it might seem very difficult to make a hollow mast, but if care and proper material are used, the job should not be too difficult. The process is explained clearly in the rigging plan which is reproduced on the opposite page. The boom, jib club, and spinnaker pole are not hollow. The metal fittings can be homemade, if you prefer, but the increased popularity of model yachting has made it possible for them to be manufactured in reasonably large quantities, with a consequent decrease in prices. Unless you have ideas of your own on the design and placement of fittings, it hardly pays to make them yourself. permanently in place until the rud- Contrary to common impression, sails cannot be made, with any degree of success, from old bed sheets. ter still, bring the part you have sawed off to a foundry, and have them and drilled for the fastening bolts as well as the pivot. Do not fasten this der is on. Now we are ready for rigging, but before we do so it is necessary to launch our hull and make a flotation test. Place a one-pound weight on the deck at station 5 to represent the There are several kinds of excellent sail cloth, woven especially for model yachts, now available, and you could not do better than to use one.

Make cardboard templates from the cross sections of the hull, and use them to shape the keel, applying them as shown in the small sketch. Now two pieces have to be cut out of the keel you have just made. One is for the rudder, which is made as illustrated in drawing 6K, and mounted as illustrated in 7K.

On May 28th the day started By C. O. BROOK with F PROOF of the growth of model yachting is needed, let me furnish that proof in actual figures. These figures do not include unregistered clubs or models, but only those actually making up the two National Associations, Great Britain and the United States. The M.Y.A. (British) composed of the following, since it was organized in 1911: Scottish Clubs, 10; Northern England, 23; Midland, 8; Eastern, 6; Metropolitan and Southern, 20: Southwestern (Wales, Cornwall, etc.), 6; Ireland, 2; New South Wales, 1; Africa, 1; giving a total of 72 clubs. The M.Y.R.A.A. (U.S.) has 52 clubs in Eastern, Mid-West, and West Coast Divisions. It was organized 1924. While the British show a greater number of little or no wind, and going was slow, even with only nine entries, but by noon the breeze picked up and slipped into the Northeast held at five knots for the rest of the day—when one half of the second round had been completed. Sunday opened with a smart breeze throughout the morning and held to the ful in the extreme, holding off the heavy downpour of rain until we were putting our yachts away for the day. Monday was a repetition of Sunday, but wita the wind down to ten knots. Well, we went there to sail, and I doubt if any skipper can criticize either the amount of sailing or the manner in which the races were sailed or handled. The result follows: Lochman (Club?) ……….. Willis, Mill Pond M.Y.C. …. 116 L111 west of north where it moved late Saturday. By noon it was piping at a great rate, reaching a maximum of some twentyfive knots by 4 P.M.

With only four pair to sail in each board, and the keen breezes, it was a steady trek up and down the pond for the entire three days for skippers, mates, and judges. The weatherman was thought- Wm.

Invitation races models registered than we do in America, it is because they have six classes of models, Ten Rater, Six-Meter, M class, A Class, 36” Restricted, and 30” Restricted, all of which must be registered to com- pete in club and inter-club events. Even so, we Americans have approximately 60% as many registered models as has England. Now—if club members really wish to make the sport grow even more rapidly, let them register their models. It is only fair to the sport and to yourself, be- cause the finances from clubs to the M.Y.R.A.A. are used to advance the sport nationally, and therefore internationally—and this is not solicited advertising by the M.Y.R.A.A. but an undeniable fact. Another fact worth mulling over is that in Great Britain, “Individual Mem- bers’ are carried who have a vote equal to an entire club, which America grants to no one.

Through this “mag” I received a letter from G. F. Shentield, 122 Sth St., Lewistown, Idaho, who wants data on rigging a model and is anxious to start a Club. It will be the first in that State as far as I can learn. Makers of sails, fittings, plans, etc. might contact “G.F,” and get him started—(you, © Medford). — of too, Farley, I have been the recipient of a number letters with friendly cause I said the “X”’ Shelf.” a As result, Farley says they have “put in your “A’ boats with ‘em, and we’ll do that. The Hartford M.Y.C. certainly were initiated into skiff sailing at their InterClub race with the Deeper Hudson M-Y.C. With a near gale from the south-southeast, the trip down the lake on a dead run, the close reach to the second buoy and the beat home gave the skippers a tough time.

We find it hard to imagine a more congenial group anywhere. Every: one enjoyed every moment of their stay if my own experience speaks for the crowd, and I’m certain it does.

One thing we noted about our guests was that their yachts were all finely built and exceptionally neat. The two trophies, one donated by Vic Hanner and the other by Charles Heisler of the Deeper Hudson M.Y.C., were for the guests, and their gratitude was something to think about. We never expect to meet a more friendly group of skippers anywhere. Everything was taken as part of the day’s fun. The results were: Vic Hanner 200, Paul Heisler 200 (both D-H men); Al Adams, Hartford, 175; Dix Belgrave, D-H, 175; Doc Allen, D-H, 100; H. Graffunder, Sr., 75; H. Graffunder, Jr., 75 (both D-H); B.

All‘in all it was a blustery event aud we know our guests were not intimidated against skiff sailing because of it. They wonder where Cecil got that control. This scribe attributes his sailing not to mountain sheep and made adjustments like a veteran. You’re a lucky Skipper, Cecil—that work should be worth a set of furs to any man. (O.K., Mrs. D.?) The results follow with a (*) showing those who sailed only one day: C. Drake, Atlantic, 258; Ben Chapman, Lynn, 167; Island, 134; H. Higginson, Boston, 131; A. Holmes, Boston, 131; R.

We received a nice letter from Ted Jacobs, 2027 Webster Ave., New York City, Secretary of the Empire M.Y.C., inviting interested folks to join their club. Ted is enthusiastic to say the least, and we know their club is going far and strong with such sincerity of purpose as Ted puts forth. New Yorkers interested should contact him and get into a real sport. They entered seven boats in the Nassau M.Y.C. Invitation race on May 28th. Saying they are all “green” at the game, they gave a fine account of themselves.
