This publication therefore brings the catalogue section right up to date, though we are aware that we can never maintain our lists in this happy state for long, as each month new designs are added to the range that cannot be catalogued until the next reprint. We prefer this to any attempt at listing “futures”, which cannot be made available until they have been published in our monthly magazines. In addition, opportunity has been taken to answer some of the multitudinous questions that are put to us weekly by enthusiastic modellers, for it is obvious that the public to which we cater varie: considerably both in its tastes and degree of knowledge of the modeller’s art. We are sure that the many articles included i this Handbook will be of great assistan to expert and beginner alike, for t subjects have been selected with gre care, and based on a careful study of t requirements of ““AEROMODELLER” an “MODEL MAKER” readers over the pas! years. Remember, the A.P.S. range has beer compiled by modellers, for modellers, anc within the limits of business economy endeavours to meet every aspect of the world of modelling. In our humblk opinion, acquisition of the new Plan: Handbook is money well spent, a state ment which we trust you will confirm after a careful perusal of its contents.

Model yacht racing in-this country is controlled by the Model Yachting Association, who recognize six official classes. Each class has special rules, but the general characteristics in order of size are as is unlimited. follows: Three of these classes are recognized internationally, the “A”, the 6 metre, and the Marblehead; the last mentioned is probably the most CLASS Built to a special formula, ‘‘A” boats are norm- ally between 6 and 7 ft. long and between 50 and 70 lb. displacement, with a mast up to 8ft. in length carrying a sail area averaging around popular class of model yacht at present in existence. Would-be yacht builders are advised to contact their local clubs before finally deciding upon the design, since few clubs race every class of model, and there is little point in producing a class boat 1,650 sq. in. RATERS for which there is no local competition. In addition to the above officially recognised classes, a further class was introduced by “Model Maker” at the beginning of 1955, and this is known as the Half-Marblehead or M.M. class. The principal characteristics of the specification are a maximum length of 25 in. and a maximum sail area of 216 sq. in. The idea behind this class is to provide a cheap and easily built boat of interest to newcomers and junior yachting enthusiasts, and it is hoped that official recognition will be granted to the class when sufficient models are being raced. At the time of printing no fixed rules for radio coutrol yachts have been decided upon, but it appears unlikely that a special class of boat will be created and that either the Marblehead or 10rater will be adopted as a standard class. roughly | 1-1,200 sq. in. 6 METRE Very popular in Scotland, these boats are the nearest approech to scale model yachts and are built to rather an involved rule. Length is normally a little over 5ft., displacement in the order of 32 or 33 lb., plus a crew weight of 21b., carrying somewhere between I! and 1,200 sq. in. of sail. MARBLEHEAD Of American origin, Marbleheads are built to the simplest specification, the main features of which are a maximum length of 50in., and a maximum sail area of 800 sq. in. Displacement is normally between 20 and 24 Ib, MODEL MAKER—the only boat magazine 87 = 10 These boats are also built to a special rule and approximate 6 ft. in length, weigh somewhere between 25 and 30[b., and carry a sail area of —_<_ “A” RESTRICTED The smallest recognized class, the basic rules being that the hull must fit into a box 36x9x II with a maximum displacement of 12 Ib.

The first and simples t of the two is the hard chine hull, where definite “corners” exist between the sides and bottom panels; in such a boat the sides and bottom panels are virtually flat for all or most of the length, although centre on the other hand, curves gently from gunwale to keel, with no suggestion of a “corner”, and calls for rather different constructional method s. HARD CHINE HULLS This type of hull is most often built on permanent frames or bulkheads ally, however, removable after “shadows” completion, are used, especially where light weight is desirable. The frames or shadows are shaped and fitted to a jig which, in power boats especial ly, be the actual keel. Longitudinal may strips are then affixed to form the inwale and chine, and sometimes additional stringers are added as stiffeners. The planking is then fitted to these strips. The planking is frequently sheets of ply, etc., which cover the whole side or half the bottom in one piece; sometimes case, double flat plate built removed from the jig (if an externa l one is used) and the shadows (if any) knocked out. Interior details and deck, etc. are then added. Most modelling materials lend themselves to this type of hull, and balsa, obeche, spruce, or birch are often used. The most frequent material specified, however, especially for skinning, is resinbonded plywood, which is easily available in all sizes from y in. thickness upward. ROUND BILGE HULLS The simplest form of construction for hulls of this type is to carve the whole unit PLANKING 90 latter or stern end, is usually a ES DIAGONAL the in as a bulkhead.

Occasio n- line. diagonal planking is frequently specified; this means that a second skin of narrow strips is laid over the first, sloping at 45° in the opposite direction, At the bow, a block or blocks may be called for, to simplify construction by obviating that varying in angle throughout.

This is an expensive and TRANSOM" means, wasteful apart VERTICAL CENTRE PLANKS BREAD ®& BUTTERING CUT TO BUTTOCK LINES SECTION DECK LINE from the difficulty of obtaining good quality material in sufficiently large sizes, and as a result “bread and butter” building is employed. In this system the “bread” is the timber and the “butter” the glue used to bond the planks together. It has the advantage of being less wasteful and of rendering hollowing much easier. The hull profile and cross-section are first divided off on the plan into slices of the thickness of the planks available, and the top line of each division is used to mark off the outline for each slice on the timber—there is after all, little point in making a low “slice” the same size as the top one when it will have to be carved down anyway. Inside the outline a second shape is drawn and this shape is also sawn out and removed, thus considerably reducing the amount of internal hollowing to be done. After glueing the planks together, the outside is carved to its finished contours, using templates traced from the drawing, before completing the internal hollowing. Ribs, bulkheads, and other interior details are added after the hull shell is completely finished. An alternative system becoming popular is “bread and buttering on the waterlines”, which entails the use of vertical planks. The most common material for bread and butter construction is obeche, which is available at most timber yards and model shops. Sugar pine, yellow pine, mahogany, and red cedar are also excellent timbers for this job, though more difficult to obtain. Planked hulls, either clincher (overlapping) or carvel (flush) built, are constructed in two ways, depending on whether permanent frames are fitted. Procedure is much the same, except that permanent frames are cut to the crosssection of the hull less the thickness of the planking, while in the other case, the or (“moulds” frames temporary “‘shadows’”) are cut to finished cross- BREAD & BUTTER CONSTRUCTION SECTION CUT TO WATERLINES TOP PLANKS 91 a o section less the SHADOWS ALTERNATIVE SHADOW FITTING thickness of the HeiY~ planking and the Sw ribs.

When set up (upside down), the keel, inwales, stem, and transom are fitted to the frames, and the ribs (if any) lightly pinned in place. Planking is carried out, usually starting with the garboard strakes (next to the keel). After completion and sanding of the planking, the jig is Some of the advanced ““MoDEL MAKER” yacht plans consist of lines only, but there is no difficulty in building a hull from the information given. The shadows can be drawn directly on to the ply from the plan, allowing for planking thickness, etc., and set up on a jig in the manner described above. is Alternatively, the planks for bread and buttering may be taken directly from the water or buttock lines shown on the drawing.
