HE Braine gear, described in detail in the December issue of YACHTING, for the International Model A Class yachts, requires special fittings that make this type of gear sensitive and positive. After fitting quadrant to the rudder post and arranging the running sheet as shown in the diagram, the lead is run through an eye on the main boom to the bowser running parallel to the main boom. This bowser consists of a stout line of cotton, linen or hemp, and two slides. One slide is used to keep the line taut and the other is used to make fast the other end of the running sheet certain distance from shore without assistance. The single guy is the most popular, as the double and triple guys divide the tension. One end of the guy is hooked to the outer end of the boom. The other end, which has a short bowser for adjusting tension, is hooked to an eye placed about amidships on weather rail. This phase of model yacht sailing is most interesting. It requires considerable practice to know the amount of tension required to make the yacht “guy” when necessary. The Liverpool Boy is a guy made of rubber about four to six inches long, with a hook on one end, fastened to leeward chain-plates; the other end, with a bowser for adjustment, is passed through an eye on the rail —_DYPES OF GOWSERS 2 SLY5 YLSEO WITH BRAIME STEERING GERA. to an eye on the jib pole, placed about three inches eas? =—8 inboard from jib stay. The object of this guy, used with the beating guy only, is to hold the jib to weather after tacking. Joun Brack. Explanation of Yachting Monthly Cup Rules ‘THe Yachting Monthly Cup Rules published in the October issue of YACHTING are based on a full sized yacht: 6 metres= 19.68 feet. For this reason the rule is rather perplexing if one is not familiar with reducing full sized yachts to models. er The rule states that all models must not exceed 6 metres (19.68 ft.) on a scale 2 inches=1 foot. For a scale of 2 inches=1 foot, a model will be !/eth the size, or 6 metres (19.68 feet) <"*/,= 39.36” rating. For scaling down the other dimensions of the for- mula the following table will explain how it is done. 100— “LWL in inches= 1” = 1 ft. 100— “LWL. in inches= 2” = 1 ft. 2 MAX. pisp.= Wh 4 5=1"=1 ft. eta 2"=1 ft.

The slides, of which there are several types (the most popular are shown in sketch), are made of stout wire, aluminum, brass, bone, or wood. Their function is to make quick adjustments and to have the slide stay fixed by og the line jam in the slide when there is a strain on the sheet. It is suggested that two bowsers be fitted on the main boom — one for the running sheet and one for the beating sheet. The beating sheet is the same as that always used, and hasa hook, generally placed about one inch abaft the quadrant, to snap on the traveler. When reaching or running, the beating sheet is unhooked and wrapped around the end of the boom so as not to foul gear on deck. Both beating and running sheets may be used at the same time for close hauled work, when a slight helm is needed. The amount of helm is limited by the beating sheet. For jib steering another pair of sheets is used. The ends are hooked in quadrant and led through pulleys set in the deck just abaft the jib traveler and then made fast to a hook. There should be two sets of bowsers on the jib pole — one for beating and one for jib steering. When not in use the jib steering sheet is unhooked from the bowser on jib. Jib steering is used for giving helm when close hauled, for reaching or for forcing the yacht back on her course after she has jibed with spinnaker set. No other steering gear can accomplish this latter trick.
