This type of fra,me is constliuot,ed in such a imv that little Cross-grain oocurl.a, and the frames ar.e r.e-inf’orced by permanent floors which r`in transversely across the lower part of the .frames. This method is reoormended as the e8S±?83ia#±%ge::e:n:t::::da:%F%::i ribs or timbers. over or under The I.iba are bent battens fastened to tenporary^ mouldE3, and take a natur`al bevel. Ribs must, be mortised into the backbone 8o the planking will lie.fluE}h with the I.abbot. There is nothing wr.ong with this method, butt more wol.k is entailed than with the method fir’st desol.ibed here. (1\. 3) Fastening planks to frames Sawn out of plywood, or web fra,meg. This, method ls NOT recommended, as the center layer of plywood has a. lot of` end gr.aim, and the layer.a ar’e apt to bulge or split. Plywood ig also excesE]ively heavy and should be used. only on very small mod,els where three or four fr.anes are Buff.icient. 4) Fa,Eitening pla,nhs to steamed a,nd bent ribs or timbers, where the I.iba are shaped on the edges of many temporal`y moulds. It ia difficult to keep plank fastenings from entering into the moulds, and if moulds are removed and the ribs left without :Pe:£e::PB;0:::r :i:p:tb9TEg 8::t£.:i is desor.ibed in cer.ta,in text-books, but Should be avoided, as they are now out-dated.. is very litt,1e differ6noe ln weight between the two methods.

June, 194o •yl Noav oo7nb4Thed, avith MODEI, CRArTSHAN SAIL PLANS Dimensioned and Balanced for the Marblehead Class MODEL RACING YACHT HERE in Wisconsin, frequently encounter highwhere wind skippers velocities during the course of our model yacht racing season, it is almost essential that our craft be equipped with first, second, and even third suits of sails, while the hulls themselves remain of such a desigii as to be driven easily on those days when the winds are light. This situation compels many of us to make more than a casual study of our sail requirements. Naturally, every model yachter crowds the al`ea restrictions in his No. 1 suit o£ sails in order to get the most out of his boat on the “light” days. When this suit (and the wind) causes too great a heel in the hull, with a consequent slowing-up of the speed, it is time to put on the second suit, continuing to the third, if the second proves too large. There doesn’t seem to be any hard and fast rule as to how much smaller the second and third suits should be, nor would this be Practical, because of the variations in the different hull recovery powers. However, it is a fairly general practice to obtain the maximum area permissible in suit No, 1, 10 per cent less area in suit No. 2, and 20 per cent less than No. 1- in suit No. 3. If there are to be only two suits, the smaller m£#n;e:Ee::Ire:enhta]veess.been developed with regard to the Scale: %” to 1″, glven in hundredths. Suit No. 2 measurements in parenthesis. SAIL AREAS.

The relationship of all these factors has been given consideration-as well as the balancing of the two suits of sails. On a conventional Marblehead design the sail plans suggested should prove most satisfactory, although it is generally advisable to follow the sail plans accompanying any hull blue print. That every sail Plan must be balanced on the craft with which it is used is a foregone conclusion, but once a balance has been achieved no further difficulty should be experienced when comr`lete changes from first to second suits are made, as the general balance will remain apprt,..{imately equalized. The 1/8″ concave/convex curve of the mainsail luff provides for a flat upper surface and a more flowing curve in the lower section. This seems advisable in such a moderately high sail plan. The .14″ concave jib luff will furnish a fairly flat surface, but not to such a point where all jib pulling power has been lost. The forward, and lower, position of the center of effort in the No. 2 suit will do much to correct for the differences between higher winds and faster motion as against lighter winds and slower motion. The high-cut clew of the mainsail should prevent the boom dragging, which would make your steering gear inoperative, and the loose foot can be made adequately flat by tightening up on the outhaul in heavier winds. The ratios of the component parts will be found in the figures accompanying the illustration. These €`re some of the factors weighed in submitting these balanced and dimensioned sail plans. Like the experienced golfer who finds that a balanced set of golf c.lubs improves his game, so you will find that a balanced set of sails will improve your yacht’s performance. WANTED !
